COB: True Off Delay Plug-In Timer

• No Power Required

  During Timing


• 2-Wire Off Delay


• Digital CMOS Design


• 10 Amp, DPDT


• ±0.2% Repeatability


• Transient Protected


• Timing Ranges Up to 

  1 Hour


True Off Delay

Application of the input voltage will energize the internal relay, transferring the output contacts and charge the internal storage component. When the input voltage is removed, the relay remains energized and the timing begins. At the end of the timed period, the relay will be de-energized and the timing circuit will reset. Re-application of the input voltage during timing will reset the COB and the relay will remain energized. The input voltage must be applied to the COB for a minimum amount of time to ensure proper operation of the timer or the internal relay will energize and not time out (see specifications).
