Description

The ABB CI840A PROFIBUS DP‑V1 Communication Interface Module is a high‑performance fieldbus interface designed for industrial automation networks. It enables seamless communication between distributed S800 I/O systems and PROFIBUS DP‑V1 control systems such as AC800M controllers and PLCs. The module supports PROFIBUS DP‑V1 protocol, supervisory I/O functions, hot configuration in run, and HART pass‑through for intelligent device connectivity.

Built for redundant applications, the CI840A supports line and module redundancy, enhancing system reliability and minimizing downtime. Its hot‑swap capability allows module replacement without disrupting operations, making it suitable for demanding industrial environments such as manufacturing, process control, and utilities.
