CI801 3BSE022366R1 ABB Communication Interface Module CI801 PROFIBUS DP-V1

The ABB CI801 (3BSE022366R1) is a high-performance communication interface module designed for the AC 800M family of programmable automation controllers (PACs) within ABB’s System 800xA distributed control system (DCS). Serving as a critical gateway between the AC 800M controller and external field devices or higher-level networks, the CI801 enables seamless integration of Modbus RTU/ASCII serial communication into industrial automation architectures—making it essential for legacy device connectivity, remote I/O linking, and cross-system interoperability.

Engineered for reliability in demanding process and factory automation environments, the CI801 supports robust, real-time data exchange with third-party equipment such as power meters, variable frequency drives (VFDs), PLCs, analyzers, and HMI panels that use Modbus over RS-485 or RS-232. With hot-swap capability, redundant power support, and full compatibility with ABB’s Control Builder M engineering suite, the CI801 ensures flexible, future-ready system design with minimal downtime.
