SERIES 4000 LED TIME DELAY PLUG IN CONTROL MODULES

Why are time delay logic circuits needed in relay protection

Why are time delay logic circuits needed in relay protection

A time delay relay controls the timing of electrical circuits by delaying switching operations. While conventional relays provide immediate switching, many processes require a controlled delay —for example, starting motors in sequence, delaying lights, or keeping equipment running briefly after power is removed. The normal relay changes its contacts instantly on energization and de-energization of the relay coil. Here is a simple chart to compare them: Think about needing a motor to start ten seconds after you press a button.
