PRS65
Single Shot Timer
Description
The PRS65 is a single shot time delay relay for use on noncritical timing applications. The knob adjustable time delay
carries a guaranteed time range of up to 8 minutes.
8-PIN
Operation
Power must be applied to the input at all times prior to and
during timing. Upon closure of the initiate switch (momentary
or maintained) the output contacts transfer and the time delay
is initiated. At the end of the delay interval, the output contacts
revert to their original position. If the initiate switch is reclosed
during timing, the time delay will not be affected.
