How Does a 8 Pin Relay Work

In a normally open relay, power flows through an input circuit, activating an electromagnet. This generates a magnetic field that attracts a contact to join with the second, larger circuit, allowing current to flow through.

How do you test an 8 pin relay with a multimeter?

Take out a multimeter and place it in the ohmmeter (Ω) setting. Place one probe on the COM terminal and the other probe on the NO Terminal. Make sure that you read a high resistance of several megohm (MΩ). If you do, then the NO Terminal reads the correct resistance and should function properly.
