Frequently Asked Questions

What is timer in control circuit?

The timer is a relay having such an output (with or without contact) that electrically closes (turns ON) or opens (turns OFF) the circuit after a preset time elapses when electrical or mechanical input is given.

How does a time delay circuit work?

Time delay relays are simply controlled relays with a time delay function built-in. They control an event, by energising the secondary circuit, after a certain amount of time or for a certain amount of time, some can even do both.
