Electromagnetic Power Relay

A Relay is a switching device that may operate electronically or mechanically. Electromagnetic Relays are widely used in machine tool control, industrial assembly lines, and commercial equipment. 

One of the main reasons why relays are much popular is because they can control a large amount of output. And we are all aware that the output in an electronic device is much higher than the electrical input received.

The implementation of a relay is significant in two given situations -

  • When it is important to have a low power signal controlling the circuit
  • When there are several circuits aimed to be controlled by the same signal.
