Timer Circuit For Automatic Switch OFF Any appliance After a fix Time Duration. The timer activates a relay through a bipolar transistor in order to connect or disconnect the The next two diagrams show the proposed PCB for this circuit and an image of what would be the finished circuit. In the circuit diagram, the IC works as a monostable multivibrator.

You can watch the following video or read the written tutorial below.

Here we use the simple logic that when trigger pin is grounded, output is a high logic can this circuit works as UPS relay changeover with zero crossing detector?or it should be add zero crossing circuit?
