Time Delay Relays Dedicated - Interval TSD7 SERIES Interval/Delay-on-Break Timer Description The TSD7 Series utilizes only two terminals connected in series with the load. Interval timing mode period is achieved by using a small portion of the AC sine wave allowing sufficient voltage for circuit operation. It can be used as an interval timer to control or pulse shape the operation of contactors, solenoids, relays, and lamp loads. The TSD7 Series can be wired to delay on the break of a switch for energy saving fan delays. Operation (Interval) Upon application of input voltage, the output energizes and the time delay begins. The output remains energized throughout the time delay. At the end of the time delay, the output de-energizes and remains de-energized until power is removed. Reset: Removing input voltage resets the time delay and the output. Wiring Diagram Operation (Delay-on-Break) Upon closure of SW1, the load is energized and the timer is L1 N/L2 reset (zero volts across its input terminals). Opening SW1 re- applies input voltage to the timer, the load remains energized and the time delay begins. At the end of the time delay, the Interval output de-energizes. If SW1 is open when power is applied, the load will energize for the time delay then de-energize. Reset: Reclosing SW1 resets the timer.
