Resistance Across Relay Coil at Sarah Case blog

Resistance Across Relay Coil. When current flows through relay coil it creates the necessary magnetic field which then opens or closes the relay contacts. You only need a resistor in series with your relay coil if your are applying a voltage that is different than what your relay coil is rated for. At the rated voltage, the coil resistance will. Find out what resistance values are normal and what indicates a bad coil. But to be sure, measure the contact resistance. Learn how to use a multimeter to check the coil and contact terminals of a relay for resistance values. Learn how to check the resistance of a relay coil using a multimeter and a simple diagram. If you hear the relay contact clicking, then it perhaps working. Test the resistance across each relay pole and its nc and no contacts with a dmm. Each nc contact should read 0 ohms to. Find out what resistance readings indicate a good or defective relay and how to. One way to test the relay is to apply and remove the stated voltage across the coil (12 vdc for those shown) and check continuity across the contacts with a multimeter set to ohms. If so, get a voltage source and apply across relay coil pins.
