Time-delay relays

Time delay relays are simply control relays and used to control an event based on time. The difference between relays and time delay relays is when the output contacts open & close: on a control relay, it happens when voltage is applied and removed from the coil; on time delay relays, the contacts can open or close before or after some time delay. Time-delay: there are two sorts of time-delay relays: make or break. • Make: when a current is passed through the relay, its coil only actuates the contacts after a predefined time (often adjustable), and they return to the initial position instantaneously as soon as the relay is no longer powered. • Break: when a current is passed through the relay, its coil instantaneously actuates the contacts. When the coil is no longer powered, however, the contacts return to their initial position after a predefined time, depending on the time-delay setting.
