Description Of Function

Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the time delay (t1) begins. At the end of the time delay (t1), the output is energized and remains in that condition for the time delay (t2). At the end of the time delay (t2), the output is de-energized & the relay is ready to accept another trigger. During both time delay (t1) & time delay (t2), the trigger is ignored.

Operation

The TD-8 series of time delay relays offer an easy and accurate way to select any time delay between 50ms & 10,230 hours (100ms & 1,023 hours on single-function units). Programming is accomplished through the use of 10-position DIP-switches. This method provides a greater setting accuracy than is found on other units with an analog potentiometer. An LED indicates relay status.

The TD-8 series comes in two versions: a multi-function product with 16 functions built-in or a single function product.
