A relay logic circuit is a schematic diagram which shows various components, their connections, inputs as well as outputs in a particular fashion. It contains two vertical lines, one on the extreme left and the other on the extreme ri. The working of a relay logic circuit can be explained through the given figures- This figure shows a basic relay logic circuit.

Anti-Pump relay also provides protection from repeated closing in the event breaker close switch gets jammed in the close position. If the TNC switch fails (Trip normal close) or there is any problem with the CB (circuit breakers) closing circuit, the continuous CB (circuit breakers) close command can be extended to.

Electromechanical relays can be classified into several different types as follows: "Armature"-type relays have a pivoted lever supported on a hinge or knife-edge pivot, which carries a moving contact. These relays may work on either alternating or direct current, but for alternating current, a shading coil on the pole is used to maintain contact force throughout the alternating current cycle.
