ABB 1SNA608017R0600 NSNBC01 Relay

ABB 1SNA608017R0600 NSNBC01 Relay is an ABB interface relay/optocoupler (OBC0100-24VDC) designed to isolate control circuits from the load side in industrial automation. As part of ABB's 1SNA NSNBC01 family, the module accepts a 24 V DC input and provides a signal-isolated relay output suitable for interfacing PLCs or other controllers with higher-power devices, while preserving galvanic isolation. The product designation 1SNA608017R0600 corresponds to the OBC0100-24VDC interface module, emphasizing its role as an interface relay/optocoupler rather than a standalone power relay. Typical applications include machine control panels, automation cabinets, and distributed control architectures where a low-voltage control signal must safely actuate a relay or optocoupled output. Verified details drawn from ABB's interface-relays catalogs and official product listings confirm the 24 V DC coil designation and the NSNBC01 variant; users should consult the exact ABB bill of materials or distributor listings for any variant-specific pinout or contact configuration. Because it is an interface device rather than a power relay, the unit provides isolation between the controller and the load, helping protect sensitive electronics from surges and noise while enabling reliable switching of actuators, indicators, or safety interlocks in automated systems.
