Manufacturers : Electronic components : Relays : Time delay relays

A time delay relay is used to provide a mechanism for turning a device on or off after a predetermined amount of time. For example, in order to avoid damage to equipment and/or ensure safe operation of certain equipment due to electrical power interruptions, time delay relays are utilized to ensure equipment stabilization by provide a waiting period after restoration of power of a duration in excess of some critical interval of time to prevent immediate supply of relatively high operating voltage to the equipment. Time delay relays use a variety of components including solid-state, electromechanical, thermal, and pneumatic devices to establish a delay period. Time delay relays may be operated in two modes, "on delay" and "off delay." In the "on delay" mode, the time delay in actuating a set of switch contacts occurs after the energization of the associated electromagnet. In the "off delay" mode, the time delay occurs upon the de-energization of the electromagnet, so that the return of the delayed action switch contacts to their normal state, either normally open or normally closed, lags movement of the electromagnet.
