ORM SERIES
Description
The ORM Series features open PC board construction for
reduced cost. It has isolated, 10A, DPDT relay contacts and all
connections are 0.25 in (6.35 mm) male quick connect terminals.
The time delay may be ordered as factory fixed, onboard knob,
or external adjustment. Time delays from 0.05 - 300 seconds.
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 energizes and remains
energized until voltage is removed.
Reset: Removing input voltage resets the time delay and output.
