ABB 1SNA645013R2600 Industrial Interface Relay Module

ABB 1SNA645013R2600 is a boxed interface relay module (RB122G-230VUC) featuring a double-pole double-throw (DPDT) contact arrangement that provides galvanic isolation between control logic and higher‑power loads, making it suitable for panel‑mounted automation in demanding industrial environments. The unit uses a 230 V AC/DC coil that can be energized from either AC or DC sources, and it incorporates screw-terminal connections for reliable field wiring in control cabinets or machine interfaces. Each pole offers normally open and normally closed contacts, with an overall rating of up to 8 A at 250 VAC per pole, enabling safe, clean switching of common industrial loads while keeping control circuitry insulated from load networks. As part of ABB's R600 family of interface relays, this model is designed for modular integration in automation systems where compact signaling isolation and robust load switching are required for dependable machine operation.
