Delay On Make (Operate) ORM Series Time Delay Relay Description The ORM Series features open PC board construction for reduced cost. It has isolated 10 A 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 to 300 seconds. Operation Low Cost Open PCB Construction Time Delays From 50 ms ... 300 s in 5 Ranges 10 A Double Pole Double Throw Relay Output +/-2% Repeat Accuracy +/-10% Factory Calibration Fixed, Adjustable on Unit, or External Adjust Function 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.
