What Is The Working Principle Of Time Relay?

The working principle of a time relay is a very simple mechanical principle. The time relay is an automatic control electrical appliance that uses electromagnetic principles or mechanical action principles to delay the closing or breaking of contacts. Its characteristic is that there is a delay between the time when the attraction coil receives the signal and when the contact moves. Time relays are generally used to control the motor starting process with time as a function. After the relay receives the action signal, its output circuit requires a specified accurate time to generate a reaction action. It is an electrical component used on lower voltage or smaller current circuits to connect or cut off higher voltage and larger current circuits.
