Operations
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.
