Relay Coil Resistance. This post provides some insights into testing methodologies. one way to test the relay is to apply and remove the stated voltage across the coil (12 vdc for those shown) and check. Testing parameters such as response time, input & output characteristics, and others are common testing. Observe if there is no burnt marks, mechanical deformations or unusual smell. A dc relay coil has resistance that limits the dc current. Also see application note “coil voltage and temperature. in order to check to see if the relay's coil is good or bad, one of the best methods is to check its resistance. Check initial state of the relay contact. An ac relay will remain contact closed due. if the measured resistance matches the resistance mentioned in its datasheet, the relay coil is fine. If there is a doubt based on the observation, then replace the relay with a new one. Observe carefully the relay coil pins, contact pins and or the entire appearance. If the resistance is very low or very high, the coil most likely has short turns or opened respectively. A relay coil's resistance should always come with the. An ac coil relies on its impedance for governing the current.
