H3CR-A 100-240VAC/100-125VDC

**Solid-state Multi-functional Timers H3CR-A** 

CSM_H3CR-A_DS_E_6_2 

## **Multiple Operating Modes and Multiple Time Ranges. DIN 48 x 48-mm Multifunctional Timer with Wide AC/DC Power Supply Range for Both High and Low Voltages.** 

- A wide AC/DC power supply range greatly reduces the number of timer models kept in stock. 

- A wide range of applications with multiple operating modes, six modes for 11-pin models and four modes for 8-pin models. 

- Ecological design with reduced current consumption. 

- Easy sequence checking with instantaneous outputs for a zero set value. 

## LR 

- Length of 80 mm or less when panel-mounted with a P3GA-11 Socket (H3CR-A8E, 100 to 240 VAC, 100 to 125 VDC) 

- PNP input models available. 

- Standards: UL, CSA, NK, LR, EN 61812-1, and CE Marking.

- **Note: 1.** DC ripple rate: 20% max. (A single-phase, full-wave-rectification power supply can be used). 

   **2.** Do not use an inverter output as the power supply. Refer to _Safety Precautions for All Timers_ for details. 

   **3.** Models with 24-to-48-VAC or 12-to-48-VDC power supply have inrush current. Caution is thus required when turning ON and OFF power to the Timer with a non-contact output from a device such as a sensor. (Models with an inrush current of approximately 50 mA and a 24VDC power supply are available (the H3CR-A-302 and H3CR-A8-302).) 

   **4.** The values are for when the terminals 2 and 7 and terminals 10 and 6 are short-circuited, and include the consumption current of the input circuit. 

   **5.** Refer to _Safety Precautions for All Timers_ when using the Timer together with a 2-wire AC proximity sensor.

**H3CR-A** 

## **Safety Precautions (H3CR-A)** 

Refer to _Safety Precautions for All Timers_ . 

**Note:** The following precautions apply to all H3CR-A models. 

## ■ **Power Supplies** 

## ■ **Input/Output** 

For the power supply of an input device of the H3CR-A@/-A@S/-AP, use an isolating transformer with the primary and secondary windings mutually isolated and the secondary winding not grounded. 

**Relationship between Input and Power -** ~~—~~ **Supply Circuits (except for H3CR A8E)** The H3CR-A (except for H3CR-A8E) uses transformerless power supply. When connecting a relay or transistor as an external signal input device, pay attention to the following points to prevent shortcircuiting due to a sneak current to the transformerless power supply. If a relay or transistor is connected to two or more Timers, the input terminals of those Timers must be wired properly so that they will not differ in phase, otherwise the terminals will be short-circuited to one differ in phase, otherwise the terminals will be short-circuited to one another. 

## **Correct**

## **Incorrect** 

The H3CR-A@/-A@S/AP’s power supply terminal 2 is a common ter-S/AP’s power supply terminal 2 is a common terminal for input signals to the Timer. Do not disconnect the wires on terminal 2, otherwise the internal circuitry of the Timer will be damaged. 

It is impossible to provide two independent power switches as shown below regardless of whether or not the Timers are different in phase.

Make sure that the voltage is applied within the specified range, otherwise the internal elements of the Timer may be damaged.

**H3CR-A** 

## **Relationship between Input and Power** ~~OS~~ **Supply Circuits (H3CR-A** @ **/-A** @ **S)** 

If a relay or transistor is connected to two or more Timers, the input terminals of those Timers must be wired properly so that they will not be different in phase or the terminals will be short-circuited to one another (refer to the figures below). 

An appropriate input is applied to the input signal terminals of the H3CR-A@/-A@S when one of the input terminals is short-circuited with the common terminal (terminal 2) for the input signals. Never use terminal 10 as the common terminal for this purpose, otherwise the internal circuit of the Timer will be damaged.

Do not connect a relay or any other load between input terminals, otherwise the internal circuit of the Timer will be damaged due to the high-tension voltage applied to the input terminals. 

With the H3CR-AP, input wires must be as short as possible. If the floating capacity of wires exceeds 1,200 pF (approx. 10 m for cables with 120 pF/m), the operation will be affected. Pay particular attention when using shielded cables. 

## **Relationship between Input and Power - Supply Circuits (H3CR AP)** 

The H3CR-A@S transistor output is isolated from the internal circuitry by a photocoupler. Therefore, either NPN or PNP output is possible.

Since the input circuit and the power supply circuit are configured independently, the input circuit can be turned ON or OFF irrespective of the ON/OFF state of the power supply. 

It must be noted that a voltage equivalent to the power supply voltage is applied to the input circuit.
