Solid-State Output Single Shot Timers - TH3PL Timers
TH3PL Timers

The TH3PL timers are solid-state output single shot timers in a fully encapsulated 2" x 2" case. Time adjust can be with onboard potentiometer, external resistor or factory fixed time.

Timing Mode

Power must be applied to the input voltage terminals continuously. Upon closure of a Normally Open (N.O.) external initiate switch, the load is instantly energized and the time delay cycle starts.

Maintained closure or actuation of the external initiate switch during the delay cycle will not affect the time delay period.

When the delay period expires, the timer will reset to its original position and the timer is ready for another cycle.
