WebJan 20, 2024 · Check the energized condition of the relay contacts. Use a digital multimeter (DMM) to test the resistance between each pole of the relay and the corresponding NC and NO contacts for that pole. All NC contacts should read infinite resistance to the corresponding pole. All NO contacts should read 0 ohms to the corresponding pole. … WebAug 11, 2024 · Of course, both relay types are governed by various industry and governmental standards. In wide use are NEMA Class A and B relay specifications. Relays designed to MIL-R-5757 specifications include those with contacts that can switch up to 10 A; MIL-R-6106 covers relays capable of switching to beyond that.
