TNP Timers
The TNP Single Shot on Make units
meet the needs of customers who require IC digital timing circuits with octal,
magnal round and 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.

Note: Tolerances on variable units are with respect to
upper limit only. Timers with time periods greater than
10 sec. will have a 100 to 1 ratio, i.e., 1 to 100 seconds, 30 to
3000 seconds. Timers with time periods less than 10 sec. will have a 10 to 1 ratio, i.e., .99 to 9.9 seconds, .5 to 5 seconds.
