## **PROGRAMMABLE | MULTI-RANGE Digital-Set | TD-7 Series Time Ranger[tm]**
The TD-781 Series offers an easy and accurate way to select a function and any time delay between 50ms and 999 hours. Programming is accomplished by using a pushbutton thumbwheel to select one of seven built-in time ranges and three pushbutton thumbwheels to digitally set the time delay required. This method provides a greater setting accuracy than is found on other units with an analog potentiometer. These units have a fi fth pushbutton thumbwheel to select one of ten built-in functions. An LED indicates timing mode and time out condition.
Single-function versions available.

## **TD-7 SERIES TIME RANGER[TM]**
## **Application Data**
## **Voltage Tolerance:**
AC Operation: +10/-15% of nominal at 50/60 Hz. DC Operation: +10/-15% of nominal.
## **Load (Burden):**
3 VA
## **Setting Accuracy:**
**Constant Voltage & Temperature w/i specifi cations:** +0.1% of set time or +50ms, whichever is greater
**For Variable Voltage & Temperature w/i specifi cations:** +1% of set time or +50ms, whichever is greater
## **Repeat Accuracy:**
**Constant Voltage & Temperature w/i specifi cations:** +0.1% of set time or +0.02 seconds, whichever is greater
**For Variable Voltage & Temperature w/i specifi cations:** +1% of set time or +0.02 seconds, whichever is greater
## **Reset Time:**
On Delay/Interval/Flasher: 0.1 Seconds Functions with Control Switches: 0.04 Seconds
## **Start-up Time:**
(Time from when power is applied until unit is timing) 0.05 Seconds for all units
## **Maintain Function Time:**
(Time unit continues to operate after power is removed) 0.01 Seconds for all units
## **Output Contacts:**
DPDT 10A @ 240V AC/30V DC, 1/2HP @ 120/240V AC (N.O.), 1/3HP @ 120/240V AC (N.C.) B300 & R300; AC15 & DC13
## **Life:**
Mechanical: 10,000,000 operations Full Load: 100,000 operations
## **Compatibility:**
Using a solid state switch to initiate the time sequence is acceptable. See _**www.macromatic.com/leakage**_ or contact Macromatic for information regarding leakage current limits and other solid state design considerations.
## **Initiating Units with Control Switch Triggers:**
Timing sequence must be initiated only after input voltage is applied to unit. Minimum required trigger switch closure time is 0.1 seconds.
## **LED:**
Red LED. Refer to instruction sheet provided with product to determine code for relay & timing status.
