TDP Timers

The TDP Single Shot on Make units are high performance analog solid-state timers with octal, magnal round and QC bases for plug-in installation. They incorporate relays which can handle up to 10 amp loads in SPDT, DPST and DPDT formats. The metal enclosure provides a high degree of RFI shielding.

Timing Mode

Power must be applied to the input voltage terminals continuously. Upon closure of a 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.
