The Phoenix Contact REL-MR-24DC/1IC (Part No: 2961341) is a high-performance Single Relay that offers excellent reliability and electrical endurance for automation and control applications. It operates at a nominal input voltage of 24 V DC and accepts a broad input range from 19.2 V DC to 54 V DC. With a typical input current of 17 mA and a response time of 3 ms, this monostable relay enables fast signal switching while maintaining low power consumption.
Built with AgSnO contact material and featuring a single normally open contact, the relay supports up to 250 V AC/DC switching voltage and a limiting continuous current of 16 A. It is specifically designed to handle heavy-duty loads with a maximum inrush current of 80 A (20 ms), making it ideal for circuits where high startup current is expected. The interrupting rating of 384 W at 24 V DC reflects its ability to switch significant resistive loads safely and consistently.
Installation is simplified through its plug/solder connection interface, and the compact 12.7 mm width allows it to fit easily into space-restricted control panels. With a mechanical service life of 30 million cycles and reinforced insulation for safe operation, the relay is compliant with EN 50178 standards and rated for continuous operation between -40 °C to +85 °C.
