Time Delay Relay
DescriptionDescription
Description
DescriptionDescription
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.

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.
