ABB 1SVR405633R7000 Pluggable interface relay - IP40

110 V AC control coil delivers reliable actuation in standard automation circuits, providing consistent pickup and release in machine control panels. This shortens wiring runs and reduces cross-talk in dense I/O racks, delivering measurable uptime gains. In practice, engineers see fewer mis-wires during commissioning, quicker fault tracing, and faster reconfiguration when process changes occur in packaging lines or material handling systems. The four changeover contacts (4 c/o SPDT) offer flexible logic, enabling single-relay solutions for multiple signals and safer isolation between input and output stages. The compact footprint reduces panel height and width, while the pluggable concept fits into existing socket families and modular holders, translating to lower hardware costs and easier spare-part inventories in process automation lines. Flat-Pin Connections simplify installation with reliable, low-impedance connections and reduce the risk of loose terminals in vibration-prone environments. Compatibility with ABB CR-MX sockets and available accessories enables consistent labeling and traceability across assemblies, accelerating commissioning. IP40 protection and a wide operating temperature range (-40 to +70 °C) support reliable performance in typical factory environments, with derating avoided up to 2000 m altitude. Certifications including CE, UL/CSA, TÜV and UR assure regulatory compliance and safe integration in control cabinets. The pluggable design supports modular scalability, enabling cost-effective upgrades and reduced maintenance time over the life of the equipment.
