ORB SeriesTimer - Delay-on-Break
Connection:
The ORB 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
xed, onboard knob, or external adjustment. All
connections are 0.25 in. (6.35 mm) male quick
connect terminals.
Operation (Delay-on-Break):
Input voltage must be applied before and during timing.
Upon closure of the initiate switch, the output relay
energizes. The time delay begins when the initiate switch
is opened (trailing edge triggered). The output remains
energized during timing. At the end of the time delay,
the output de-energizes. The output will energize if the
initiate switch is closed when input voltage is applied.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time delay
and output.

and diagrams.
