A time delay relay is an electromechanical device that controls the timing of the switching action in an electrical circuit.
It operates by introducing a delay between the application of the control signal and the response of the relay contacts.

What is the purpose of a time delay relay?
Time delay relays serve several functions in electrical circuits:
Delay-On Operation
They enable the delayed activation of devices or systems, allowing for sequencing or time-staggered control.
Delay-Off Operation
Conversely, time delay relays facilitate delayed deactivation, ensuring that devices remain powered for a specified duration after the control signal is removed.
Interval Timing
They provide intermittent or cyclical control by repeatedly activating and deactivating the connected load at predetermined intervals.
Pulse Generation
Time delay relays can generate precise pulses of specified duration, which is useful in applications requiring periodic signals or pulse-width modulation.
