Description
The PRS65 is a single shot time delay relay for use on non- critical timing applications. The knob adjustable time delay carries a guaranteed time range of up to 8 minutes. 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.
