Solid-State Output Delay On Break Timers - TH3ML Timers


Solid-State Output Delay On Break Timers
TH3ML Timers

The TH3ML timers are solid-state output delay on break timers in a fully encapsulated 2" x 2" case. Time adjust can be with on-board potentiometer, external resistor or factory fixed time.

Timing Mode

Input voltage is applied continuously. Upon closure of the normally open live external switch, the load is energized, and remains energized as long as it is closed. When the external initiate switch opens, the time delay is started. At the end of the time delay, the load is de-energized, and the timer is ready for another cycle.
