PLUG-IN, IC DIGITAL, Hot INITIATE SWITCH
TNPL Timers
Timing Mode | Single Shot on Make
Category | Timer with Relay
Series | TNPL
The TNPL Single Shot on Make units meet the needs of customers who require IC digital timing circuits with octal, magnal round or QC bases for plug-in installation. The units are available in SPDT, DPST and DPDT relay forms up to 10 amp with fixed or adjustable time periods.
Timing Mode
Power must be applied to the input voltage terminals continuously. Upon closure of an isolated Normally Open (N.O.) external initiate switch, the load is instantaneously energized and the time delay cycle starts.
Maintained closure or actuation of the external initiate switch during the delay cycle will not affect the time delay period.
When the delay period expires, the timer will reset to its original position and the timer is ready for another cycle.
