Description

The ABB 3BSE041882R1 CI840A PROFIBUS DP‑V1 Communication Interface Module is a high‑performance fieldbus communication module used in industrial automation for connecting distributed I/O systems (such as S800) to PROFIBUS DP‑V1 masters like PLCs, AC800M controllers, or SCADA systems. It supports redundant operation, ensuring continuous and dependable communication even under fault conditions, and enables cyclic and acyclic data exchange for process control. Designed for harsh industrial environments, this module delivers deterministic data transfer up to 12 Mbps, hot‑swap capability, and wide temperature tolerance, making it suitable for oil & gas, chemical, power, water treatment, and general automation applications. It integrates easily with ABB automation architectures and enhances system reliability and performance in demanding control systems.
