Description
The ORS Series’ open PCB construction offers the user good
economy without sacrificing performance and reliability. The
output relay is available in isolated, 10A, DPDT or SPDT 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 (Single Shot)
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.
