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 Low Cost Open PCB Construction Momentary or Maintained Initiation 10 A DPDT or SPDT Relay Contacts Delays From 50 ms ... 300 s in 5 Ranges +/-2% Repeat Accuracy +/-10% Factory Calibration Approvals: Function 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.
