TRM SERIES

Description

The TRM Series is a combination of analog electronic circuitry

and electromechanical relay output. It provides input to output

isolation with a wide variety of input voltages and time ranges.

Standard plug-in base wiring, fast reset, rugged enclosure, and

good repeat accuracy make the TRM a select choice in any

OEM application.

Operation (Delay-on-Make)

Upon application of input voltage, the time delay begins. The

output is de-energized before and during the time delay. At the

end of the time delay, the output relay energizes and remains

energized until input voltage is removed.

Reset: Removing input voltage resets the time delay and output.
