Lab Activity: Relays

Relays

A relay is an electromechanical switching device used to control the current in a circuit.  At one time relays were used to control almost all industrial machines and processes.  While programmable logic controllers and other microprocessor-based devices have replaced relays in large scale control applications, relays are still used in many small control applications and in situations where the relay’s current handling capabilities are needed.  Relays may be found in automotive, home, industrial and many other applications.
