Plug-In Analog Solid-State Timers - TDK Miniature Timers
TDK Timers

The TDK Repeat Cycle 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

Application of power to the input voltage terminals starts the “Off” delay cycle. At the end of the “Off” delay period, the load is energized and the “On” delay starts. At the end of the “On” cycle the load is de-energized, the timer returns to the “Off” cycle and the cycling is repeated as long as input voltage is applied. Removal of input voltage will reset the timer to its pre-power condition.
