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.
