Time delay relays are parts that activate a multitude of appliances, machinery, and equipment. Some of the applications include: motor vehicles / furnace fans / conveyor belts / dispensing equipment/ warning systems. Timing relays have a built-in time-delay function. Triggered in various ways, time delay relays minimize the energy used to start large industrial machinery or can switch on and off light switches.
