What is a power relay? The working principle of power relay
A power relay is a device that uses an electromagnet to open or close the circuit when the input (coil) is properly excited. They provide a high level of isolation between the control signal (coil) and the output (contact)-usually the rated pulse voltage is 4 or 6kV.
