Description Of Function

Upon application of input voltage, the time delay (t) begins. At the end of the time delay (t), the output is energized. Input voltage must be removed to reset the time delay relay & de-energize the output.

The TD-7 series of time delay relays offer an easy and accurate way to select any time delay between 50ms 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. An LED indicates timing mode and time out condition.

The TD-7 series comes in two versions: multi-function (10 functions in one unit) or selected single function products. The TD-781 multi-function unit has a fifth pushbutton thumbwheel to select one of ten built-in functions.
