ABB 1SVR405621R8000 Pluggable Interface Relay - IP40

Pluggable CR-U relays combine a compact module with fast replacement capabilities. The 1SVR405621R8000 provides 2 c/o SPDT contacts and a 110 V DC control input, enabling multiple circuits to be switched from a single input signal. This configuration reduces downtime during commissioning and simplifies troubleshooting by swapping the relay without disturbing the surrounding socket or wiring.Robust circular pin terminals and a DIN rail snap-on mounting support reliable field connections under vibration and repetitive operation. The design is compatible with standard CR-U sockets and a wide range of accessories, including logic sockets, pluggable function modules, holders, and markers. This interoperability accelerates installation and minimizes spare parts diversity in the control cabinet.Electrical ratings cover a broad range of control and load scenarios. With an output of 250 V AC at up to 10 A and rated DC-12 (Ie) of 10 A at 24 V, you can manage multiple loads from one relay. An insulation voltage of 250 V and an IP40 enclosure ensure safe operation in standard enclosures, while operation from -40 to +70 °C supports harsh factory environments.Modularity is a core strength for scalable automation. Using standard sockets and logic sockets, you can tailor a relay cage to meet changing control logic without redesign. The CR-U family also supports easily integrated markers and holders for clear panel labeling, reducing commissioning errors and easing future upgrades.Compliance and RoHS adherence provide assurance for regulated industries. ABB’s CR-U relays carry CE, UL/CSA, CCC, UKCA specifications, as well as RoHS information, helping you meet electrical safety and environmental requirements while maintaining supply chain flexibility.Documentation and CAD resources support faster engineering. Access data sheets, technical information, and 2D/3D CAD files to streamline integration and reduce design cycle times.
