- Character height of 12 mm for better readability (on models with 4 digits). 

- The present value display characters can be switched between red, green, and orange.[*2] 

## **Safety and Reliability** 

- Power supply circuit and input circuits are isolated for safety and reliability.[*3] 

- New set value limit and output counter functions have been added.[*4] 

## **Other Features** 

- Front Panel can be changed to white or light gray.[*5] 

- Models with instantaneous contact output added to the series. 

- *1. For 100 to 240 VAC Models with Screw Terminals 78 mm, Models with Sockets: 63.7 mm (case dimension). 

For the most recent information on models that have been certified for safety standards, refer to your OMRON website. 

- *2. The H5CX-A11, H5CX-L8 and H5CX-B Timers have only red characters. 

- *3. Specifications: 100 to 240 VAC 

Refer to “ **Safety Precautions** ” on **page 41** . 

- *4. The value of the output counter can only be monitored. It cannot be reset. 

- *5. Replacement Front Panels sold separately. 

## **Features** 

## **Basic Features** 

## **Ultra Short Body** 

The body depth has been greatly reduced. Helps in making thinner control panels. (Models with Screw Terminals) 

- 24-VAC / 12 to 24-VDC Models with Screw Terminals: 59 mm 100 to 240-VAC / VDC Models with Screw Terminals: 78 mm[*] Models with Sockets: 63.7 mm (case dimension) 

- The shortest body for a timer with isolated power supply and input circuits and a maximum ambient temperature of 55°C (according to OMRON investigation in June 2009).

## **Safety and Reliability** 

## **Isolated Power Supply and Input Circuits**[*1] 

Power supply circuit and input circuits are isolated for safety and reliability. 

Previous non-isolated timers had wiring restrictions and could be damaged if wired incorrectly. The New H5CX removes these worries.

## **Easier to Read** 

For better readability, the character height for the present value display is 12 mm (on models with 4 digits), the largest class in the industry. The wide viewing angle and brightness provide excellent visibility. The number of display segments has also been increased to make settings easier to understand, and the present value display can be switched between red, green and orange so that output status can be seen from a distance.

*1. New Models (H5CX-@-N) with 100 to 240-VAC specifications. 

## **Set Value Limit** 

You can set an upper limit for the set value to prevent unexpected operation of output devices caused by setting mistakes.

Worry-free operation<br>is achieved with the<br>New H5CX by<br>restricting the time<br>that can be set.<br>**----- End of picture text -----**<br>


## **Output Counter** 

An output counter counts the number of times that the output turns ON. (An alarm can be set and the value of the output counter can be monitored, Unit: 1,000 operations.) This counter is useful in managing the service life of the Timer or the load.

## **I/O Functions** 

For details, refer to the timing charts on **page 20 and page 29** . 

|**Inputs***1|**Start signal**|Normally functions to start timing.<br>In modes A-2 and A-3, disable timing. In mode S, starts and stops timing.|
|---|---|---|
||**Reset**|• Resets present value. (In elapsed time mode, the present value returns to 0; in remaining time mode,<br>the present value returns to the set value.)<br>• Count inputs are not accepted and control output turns OFF while reset input is ON.<br>• Reset indicator is lit while reset input is ON.|
||**Gate***2|Disables timing. (If a reset occurs while the gate input is ON, a reset will be performed.)|
|**Outputs**|**Control output (OUT)**|Outputs take place according to designated operating mode when timer reaches corresponding set value.|



*1. The H5CX-L8E@ does not have an input. 

- *2. The H5CX-L@ does not have a gate input.

   **3.** It is possible to horizontally mount Timers side by side. Attach the Flush Mounting Adapters so that the surfaces without hooks are on the sides of the Timers. (However, if Timers are mounted side by side, water resistance will be lost.)

## **Soft Cover Hard Cover Y92A-48F1 Y92A-48**

You can change the color of the front panel when mounting the Timer. The Timer is shipped with a black (N1.5) Front Panel.

## **Replacement Method** 

The Front Panel is attached to the Terminal with tabs in four locations. To remove the Front Panel, open the tabs and pull the Front Panel forward. 

**==> picture [48 x 42] intentionally omitted <==**

To attach the Front Panel, press Tabs it onto the Timer so that all four Grooves tabs lodge into the groves on the body of the Timer. 

## **Protecting the Timer in Environments Subject to Oil** 

The H5CX's panel surface is water-resistive (IP@6, UL Type 4X) and so even if drops of water penetrate the gaps between the keys, there will be no adverse effect on internal circuits. If, however, there is a possibility of oil being present on the operator's hands, use the Soft Cover. The Soft Cover ensures protection equivalent to IP54 against oil. Do not, however, use the H5CX in locations where it would come in direct contact with oil.

The Waterproof Packing will deteriorate, harden, and shrink depending on the application environment. To ensure maintaining the IP@6, UL Type 4X waterproof level, periodically replace the Waterproof Packing. The periodic replacement period will depend on the application environment. You must confirm the proper replacement period. Use 1 year or less as a guideline. If the Waterproof Packing is not replaced periodically, the waterproof level will not be maintained. 

It is not necessary to mount the Waterproof Packing if waterproof construction is not required.

**H5CX-A** @-N/-L@-N **Timer** 

## **Explanation of Functions** 

## **Operating Procedures for Timer Function** 

**Items marked with stars (** � **) can be set using the DIP switch.** 

## **Time Range (** timr **)** � 

Set the range to be timed in the range 0.001 s to 9,999 h. Settings of type ---- h (9,999 h) and ---- min (9,999 min) cannot be made with the DIP switch. Use the operation keys if these settings are required. 

## **Timer Mode (** timm **)** � 

Set either the elapsed time (UP) or remaining time (DOWN) mode. In UP mode, the elapsed time is displayed, and in DOWN mode, the remaining time is displayed. 

## **Output Mode (** outm **)** � 

Set the output mode. 

The possible settings are A, A-1, A-2, A-3, b, b-1, d, E, F, Z and S. Only output modes A, A-2, E, and F can be set using the DIP switch. Use the operation keys if a different setting is required. (For details on output mode operation, refer to **"Timing Charts"** on **page 20** .) 

## **Output Time (** otim **)** 

When using one-shot output, set the output time for one-shot output (0.01 to 99.99 s). One-shot output can be used only if the selected output mode is A, A-1, A-2, A-3, b, b-1 or S. 

If the output time is set to 0.00, hold is displayed, and the output is held. 

## **Input Signal Width (** iflt **)** � 

Set the minimum signal input width (20 ms or 1 ms) for signal, reset, and gate inputs. 

The same setting is used for all external inputs (signal, reset, and gate inputs). If contacts are used for the input signal, set the input signal width to 20 ms. Processing to eliminate chattering is performed for this setting. 

## **NPN/PNP Input Mode (** imod **)** 

Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. 

Set an NPN input when using a 2-wire sensor. For details on input connections, refer to " **Input Connections** " on **page 9** . 

## **Display Color (** colr **)** 

## **(Terminal block model: H5CX-A** @ **only)** 

Set the color used for the present value. 

||**Output OFF**|**Output ON**|
|---|---|---|
|red|Red (fixed)||
|grn|Green (fixed)||
|org|Orange (fixed)||
|r-g|Red|Green|
|g-r|Green|Red|
|r-o|Red|Orange|
|o-r|Orange|Red|
|g-o|Green|Orange|
|o-g|Orange|Green|



## **Key Protect Level (** kypt **)** 

Set the key protect level. 

Refer to “ **Key Protect Level** ” on **page 32** . 

## **Instantaneous/Time-limit (** otmd **)** 

Set the contact output to time-limit SPDT + instantaneous SPDT or time-limit SPDT operation. 

## **Set Value Upper Limit (** sl-h **)** 

Set the upper limit for the set value when it is set in Run Mode. The limit can be set to between 1 and 9999. This setting does not apply to the ON duty in Z mode. 

## **Output ON Count Alarm Set Value (** on-a **)** 

Set the alarm value for the output ON count. 

The limit can be set to between 0 x 1000 (0 times) and 9999 x 1000 (9,999,000 times). Only the underlined values are set. The alarm will be disabled if 0 is set. 

If the total ON count of the output exceeds the alarm set value, e3 will be displayed on the Timer to indicate that the output ON count alarm value was exceeded. Refer to “ **Self-diagnostic Function** ” on **page 32** for information on the e3 display. 

## **ON Count Alarm Set Values for Outputs 1 and 2 (OUT1 and OUT2) (** on1a **and** on2a **)** 

Set the ON count alarm values for the outputs 1 and 2. The limit can be set to between 0 x 1000 (0 times) and 9999 x 1000 (9,999,000 times). Only the underlined values are set. The alarm will be disabled if 0 is set. 

If the total ON count of instantaneous output 1 or 2 exceeds the alarm set value, e3 will be displayed on the Timer to indicate that the output ON count alarm value was exceeded. Refer to “ **Self-diagnostic Function** ” on **page 32** for information on the e3 display. 

## **Output ON Count Monitor Value (** on-c **)** 

The monitor value is only displayed. It cannot be set. The output ON count will be 1,000 times the displayed value. 

## **ON Count Monitor Values for Outputs 1 and 2 (OUT1 and OUT2) (** on1c **and** on2c **)** 

The monitor value for output 1 or 2 is only displayed. It cannot be set. The output ON count will be 1,000 times the displayed value.

## **Present Value and Set Value** 

These items are displayed when the power is turned ON. The present value is displayed in the main display and the set value is displayed in the sub-display. 

The values displayed will be determined by the settings made for the time range and the timer mode in function setting mode. 

## **Present Value and ON Duty Ratio (Output Mode = Z)** 

The present value is displayed in the main display and the ON duty ratio is displayed in the sub-display. Set the ON duty ratio used in ON/ OFF-duty-adjustable flicker mode (Z) as a percentage. 

**==> picture [170 x 19] intentionally omitted <==**

The output accuracy will vary with the time range, even if the ON duty ratio setting is the same. Therefore, if fine output time adjustment is required, it is recommended that the time range for the cycle time is set as small as possible. 

**Examples: 1.** When Time Range = - - - - s (9999 s)

## **Explanation of Functions** 

## **Operating Procedures for Twin Timer Function** 

**Items marked with stars (** � **) can be set using the DIP switch.** 

## **OFF Time Range (** oftr **)** � 

Set the time range for the OFF time in the range 0.000 s to 9,999 h. Only settings of type --.-- s (99.99 s), ---.- s (999.9 s), ---- s (9,999 s), and -- min -- s (99 min 59 s) can be made with the DIP switch. Use the operation keys if another type of setting is required. 

## **ON Time Range (** ontr **)** � 

Set the time range for the ON time in the range 0.001 s to 9,999 h. Only settings of type --.-- s (99.99 s), ---.- s (999.9 s), ---- s (9,999 s), and -- min -- s (99 min 59 s) can be made with the DIP switch. Use the operation keys if another type of setting is required. 

## **Timer Mode (** timm **)** � 

Set either the elapsed time (UP) or remaining time (DOWN) mode. In UP mode, the elapsed time is displayed, and in DOWN mode, the remaining time is displayed. 

## **ON/OFF Start Mode (** totm **)** � 

Set the output mode. 

Set either flicker OFF start or flicker ON start. (For details on output mode operation, refer to " **Timing Charts** " on **page 29** .) 

## **Input Signal Width (** iflt **)** � 

Set the minimum signal input width (20 ms or 1 ms) for signal, reset, and gate inputs. 

The same setting is used for all external inputs (signal, reset, and gate inputs). 

If contacts are used for the input signal, set the input signal width to 20 ms. 

## **NPN/PNP Input Mode (** imod **)** 

Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. Set an NPN input when using a 2-wire sensor. The same setting is used for all external inputs. 

For details on input connections, refer to " **Input Connections** " on **page 9** .

## **Self-diagnostic Function** 

The following displays will appear if an error occurs. 

|**Main display**|**Sub-display**|**Error**|**Output status**|**Correction method**|**Set value after reset**|
|---|---|---|---|---|---|
|e1|Not lit|CPU|OFF|Either press the reset key or<br>reset the power supply.|No change|
|e2|Not lit|Memory error (RAM)|OFF|Reset the power supply.|No change|
|e2|sum|Memory error EEPROM***1**|OFF|Reset Key|Factory setting|
|e3 ***2**|No change|Output ON count alarm set<br>value exceeded|No change|Reset Key|No change|



- ***1.** This includes times when the life of the EEPROM has expired. 

- ***2.** The normal display and e3 will appear alternately. 

When the Reset Key is pressed, e3 will no longer be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the Timer will continue without clearing the output ON count.)

- OUT1 (control output 1) turns ON when the present value reaches set value 1. 

- OUT2 (control output 2) turns ON when the present value reaches set value 2. 

Refer to **pages 18 and 28** for information on other functions. 

- OUT1 (forecast output) turns ON when the present value reaches the forecast value. 

- Forecast value = Set value - Forecast set value 

**Note:** The forecast set value is used to set the deviation for the set value. 

- OUT2 (control output) turns ON when the present value reaches the set value. 

- If the forecast set value ≥ set value, OUT1 (forecast output) will turn ON as soon as timing starts. 

## **Self-diagnostic Function** 

The following displays will appear if an error occurs. 

|**Main display**|**Sub-display**|**Error**|**Output status**|**Correction method**|**Set value after reset**|
|---|---|---|---|---|---|
|e1|Not lit|CPU|OFF|Either press the Reset Key or<br>reset the power supply.|No change|
|e2|Not lit|Memory error (RAM)|OFF|Reset the power supply.|No change|
|e2|sum|Memory error EEPROM*1|OFF|Reset Key.|Factory setting|
|e3 *2|No change|Output ON count alarm set<br>value exceeded|No change|Reset Key|No change|



- *1. This includes times when the life of the EEPROM has expired. 

- *2. The normal display and e3 will appear alternately. 

   - When the Reset Key is pressed, e3 will no longer be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the Timer will continue without clearing the output ON count.)

## **Safety Precautions for All H5CX Series (Common)** 

## **CAUTION** 

**Do not allow pieces of metal, wire clippings, or fine metallic shavings or fillings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction.** 

**Minor injury due to explosion may occasionally occur. Do not use the Timer where subject to flammable or explosive gas.** 

**Fire may occasionally occur. Tighten the terminal screws to the rated torque.** 

**H5CX terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 N** • **m) P2CF Socket terminals: 4.4 lb-in (0.5 N** • **m)** 

**Minor injury due to electric shock may occasionally occur. Do not touch any of the terminals while power is being supplied. Be sure to mount the terminal cover after wiring.** 

**The life expectancy of the output relay varies considerably according to its usage. Use the output relay within its rated load and electrical life expectancy. If the output relay is used beyond its life expectancy, its contacts may become fused or there may be a risk of fire. Also, be sure that the load current does not exceed the rated load current and when using a heater, be sure to use a thermal switch in the load circuit.** 

**Minor electric shock, fire, or malfunction may occasionally occur. Do not disassemble, modify, or repair the Timer or touch internal components.** 

## **Precautions for Safe Use** 

- The panel surface of the H5CX is water-resistant (conforming to NEMA4, IP66, UL Type 4X (Indoor Use Only). To protect the internal circuits from water penetration through the space between the H5CX and operating panel, waterproof packing is included. Attach the Y92F-30 Adapter with sufficient pressure with the reinforcing screws so that water does not penetrate the panel. 

0.5 to 1 mm 

It is recommended that the space between the screw head and the Adapter be 0.5 to 1 mm. 

- When mounting the Timer to a panel, tighten the two mounting screws alternately, a little at a time, so as to keep them at an equal tightness. If the panel screws are tightened unequally, water may enter the panel. 

- Store the Timer at the specified temperature. If the Time has been stored at a temperature of less than -10°C, allow the Time to stand at room temperature for at least 3 hours before use. 

- Mounting the Timer side-by-side may reduce the life expectancies of internal components. 

- Use the Timer within the specified ranges for the ambient operating temperature and humidity. 

- Do not use in the following locations: 

- Locations subject to sudden or extreme changes in temperature. 

- Locations where high humidity may result in condensation. 

- Do not use the Timer outside of the rated ranges for vibration, shock, water exposure, and oil exposure. 

- Do not use this Timer in dusty environments, in locations where corrosive gasses are present, or in locations subject to direct sunlight. 

- Install the Timer well away from any sources of static electricity, such as pipes transporting molding materials, powders, or liquids. 

- Internal elements may be destroyed if a voltage outside the rated voltage range is applied. 

- Be sure that polarity is correct when wiring the terminals. 

- Separate the Timer from sources of noise, such as devices with input signals from power lines carrying noise, and wiring for I/O signals. 

- Do not connect more than two crimp terminals to the same terminal. 

- Up to two wires of the same size and type can be inserted into a single terminals. 

- Use the specified wires for wiring. Applicable Wires: AWG 18 to AWG 22, solid or twisted, copper. 

- Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function. 

- When the Timer is operated with no-voltage input (NPN input), approximately 14 V is output from the input terminals. Use a sensor that contains a diode.

- Use a switch, relay, or other contact so that the rated power supply voltage will be reached within 0.1 seconds. If the power supply voltage is not reached quickly enough, the Timer may malfunction or outputs may be unstable. 

- Use a switch, relay, or other contact to turn the power supply OFF instantaneously. Outputs may malfunction and memory errors may occur if the power supply voltage is decreased gradually. 

- H5CX-A@-N/-L@-N: 

- When changing the set value during a timing operation, the output will turn ON if the set value is changed as follows because of the use of a constant read-in system: 

- Elapsed time (UP) mode: Present value ≥ Set value Remaining time (DOWN) mode: Elapsed time ≥ Set value (The present value is set to 0.) 

When in the remaining time mode, the amount the set value is changed is added to or subtracted from the present value. Operation with a set value of 0 will vary with the output mode. Refer to the timing charts on **page 20** . 

- H5CX-B@-N: 

When changing the set value during a timing operation, the output will turn ON if the set value is changed as follows because of the use of a constant read-in system: 

1. Forecast Value Setting 

   - When the present value ≥ the set value, OUT2 (control output) turns ON. 

   - When the present value ≥ the forecast value (forecast value = set value - forecast set value), OUT1 (forecast output) turns ON. 

2. Absolute Value Setting 

   - When the present value ≥ set value 2, OUT2 (control output 2) turns ON. 

   - When the present value ≥ the forecast value (forecast value = set value - forecast set value), OUT1 (control output 1) turns ON. 

   - When the set value is 0, the output turns ON the moment the signal is input. The reset operation turns OFF the output. 

- Do not use organic solvents (such as paint thinners or benzine), strong alkali, or strong acids. They will damage the external finish. 

- Confirm that indications are working normally, including the backlight LED, and LCD. The indicator LEDs, LCD, and resin parts may deteriorate more quickly depending on the application environment, preventing normal indications. Periodic inspection and replacement are required. 

- The waterproof packing may deteriorate, shrink, or harden depending on the application environment. Periodic inspection and replacement are required.

## **Precautions for Correct Use** 

- H5CX models with a 24-VDC/12 to 24-VDC power supply use a transformer-free power supply method in which the power supply terminals are not isolated from the signal input terminals. If a nonisolating DC power supply is used, unwanted current paths may occasionally burn or destroy internal components depending on the wiring. Always check the wiring sufficiently before use. 

- An inrush current of approx. 10 A will flow for a short time when the power supply is turned ON. If the capacity of the power supply is not sufficient, the Timer may not start. Be sure to use a power supply with sufficient capacity. 

- Maintain voltage fluctuations in the power supply within the specified operating voltage range. 

- When turning the power ON and OFF, input signal reception is possible, unstable, or impossible as shown in the diagram below. 

Power ON supply OFF 200ms 0 to 50 ms 5ms 0 to 500 ms Input Impossible Unstable Possible Unstable Impossible 

- To allow for the startup time of peripheral devices (sensors, etc.), the Timer starts timing operation between 200 to 250 ms after power is turned ON. For this reason, in operations where timing starts from power ON, the time display will actually start from 249 ms. If the set value is 249 ms or less, the time until output turns ON will be a fixed value between 200 and 250. The present value display will start from 250 ms. (Normal operation is possible for set values of 250 ms or more.) In applications where a set value of 249 ms or less is required, use start timing with signal input. 

## **Conformance to EN/IEC Standards** 

- When conforming to EMC standards, refer to the information provided in this datasheet for cable selection and other conditions. 

- This is a class A product. In residential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference. 

- H5CX-A@-N/-L@-N: 

Basic insulation is provided between the power supply and input terminals. (No insulation is provided between the power supply and input terminals for the H5CX-@D-N.) 

Basic insulation is provided between power supply and output terminals, and between input and output terminals. 

      - H5CX-B@-N: 

      - No insulation is provided between the power supply and input terminals. 

      - Basic insulation is provided between the power supply and output terminals. 

      - When double insulation or reinforced insulation is required, apply double insulation or reinforced insulation as defined in IEC 60664 that is suitable for the maximum operating voltage with clearances or solid insulation. 

      - Connect the input and output terminals to devices that do not have any exposed charged parts. 

- Inrush current generated by turning ON or OFF the power supply may deteriorate contacts on the power supply circuit. Turn ON or OFF to a device with the rated current of more than 10 A. 

- Make sure that all settings are appropriate for the application. Unexpected operation resulting in property damage or accidents may occur if the settings are not appropriate. 

- Do not leave the Timer for long periods at a high temperature with output current in the ON state. Doing so may result in the premature deterioration of internal components (e.g., electrolytic capacitors). 

- EEPROM is used as backup memory when the power is interrupted. The write life of the EEPROM is 100,000 writes. The EEPROM is written at the following times: 

   - When the power supply is turned OFF 

   - When switching from Timer/Twin Timer Selection Mode or Function Setting Mode to Run Mode 

- Dispose of the product according to local ordinances as they apply. 

- Attach the front panel when using the Timer. The tabs in the middle of each of four sides secure the front panel to the main body. To remove the panel, widen the four tabs and pull the panel toward you. To mount the panel, fit all four tabs correctly into the grooves on the main body.
