I recently purchase a GEYA GRT8-M 16A Multifunction Timer Relay that I intend to use for a power circuit in a control panel. It has at least 10 "functions" which include latching, pulse generator, repeat cycle, off delay, single shot, etc. I want it to work in such a way that it allows power to pass through from input to output, the first time. However, the power would go off at a certain time (based on some other aspect of the control circuitry). Now, after the power has gone off, it will come back on about a few seconds later (also based on some other aspect of the control circuitry). I want to program this relay such that when the power comes back on after this few seconds, it delays the power from passing through before letting it pass through. after the current has pass through, whenever it goes off and it come back on again, the relay delays the current for 30 minutes. It is a perpetual cycle and not a one-off. Can someone help with how to go about this?

 

Without us knowing the timer device specifications and control scheme, the very best you can get is guesses. There are over a hundred timer sources and models, many a bit different from each other.
