TD-78128

## **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:**
