Timer - Delay-on-Make
TRM Series
Features:
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.
• 10A, DPDT or SPDT output contacts
• 24 to 230V operation in ranges
• 8-pin or 11-pin plug-in
• Fixed or adjustable delays from 0.05 - 600s
in multiple ranges
• ±2% repeat accuracy
Approvals:
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 .
