Time Delay Relays

Time Delay Relays are electromechanical devices that turn a large load on or off through the use of a smaller control signal. These devices have a built-in time delay to control triggering of the relay. The functions are interval, off-delay, on-delay, one-shot, programmable (multi-function), repeat cycle, twin timer, signal on-off-delay, and star/delta controller.
