DIP-Switch | Digital-Set | TD-8 Series

The TD-8 Series time delay relays offer an easy and accurate method to select any
time delay between 100ms and 1,023 hours. Programming is accomplished through
the use of a 10-position DIP-switch. Each position is marked with a binary time
increment. The required delay is selected by moving the switch of each increment
to the ON position and adding their corresponding values (see examples below).
This method provides a greater setting accuracy than is found on other units with an
analog potentiometer. An LED indicates relay status.
