Single Shot (Pulse Former)
ORS Series
Time Delay Relay
Description
The ORS Series open PCB construction offers the user good economy without sacrificing performance and
reliability. The output relay is available in isolated 10 A double pole double throw or single pole double throw
forms. The time delay may be ordered as factory fixed, onboard knob, or external adjustment. All connections
are 0.25 in. (6.35 mm) male quick connect terminals.
Operation
Input voltage must be applied before and during
timing. Upon momentary or maintained closure of the
initiate switch (leading edge triggered), the output relay
energizes for a measured interval of time. At the end
of the time delay, the output de-energizes. Opening
or reclosing the initiate switch during timing has no
affect on the time delay. The output will energize if the
initiate switch is closed when input voltage is applied.
Reset:
Reset occurs when the time delay is complete
and the initiate switch is opened. Loss of input voltage
resets the time delay and output.
