ABB 1SNA610115R2200 Relay Module 110 VAC

ABB 1SNA610115R2200 Relay Module 110 VAC, RB122BR, is an interface-relay module in ABB’s 1SNA610 family that uses a 110 VAC coil (RB122BR variant) to switch AC loads from a low-voltage control signal. This module is designed to mount on ABB’s 1SNA610 base, enabling compact, field-installable signal relays within automation cabinets. The 1SNA610 series is described as interface relays and optocouplers, providing isolation between control circuits and AC devices. The RB122BR-110 VAC designation identifies the coil voltage while the 1SNA610115R2200 code specifies the module variant used in ABB's modular relay systems. Typical uses include local interlocks, actuators, indicators, and other AC-load switching tasks within machine control and process automation where a discrete, isolated relay is required. This part sits in ABB’s industrial control catalog as a 110 VAC coil option, and when paired with corresponding ABB interface blocks, offers straightforward integration into standard automation architectures.
