The DUB72 double undervoltage monitoring relay is approved for use in Class I, Div. 2 hazardous locations. The relay can be used to help prevent brownouts in 24-Vdc supplied systems in any kind of application, including hazardous environments. It features two independent set levels and outputs, which allow the use of one as a pre-alarm and the second one as an alarm. With a high-powered electromechanical 20-amp relay, the second threshold/relay can be used to disconnect a battery or load directly. Its low-profile DIN housing can fit into electrical distribution panels as well as into industrial cabinets.
