ABB CI855K01 MB300 Master‑Bus300 Communication‑Interface Module (3BSE018106R1)

Product Description

CI855K01 (3BSE018106R1) is a dedicated plug‑in MB300 gateway communication module for the ABB AC 800M controller, connected to the rack back‑plane through the CEX‑Bus.

It adopts the MasterBus‑300 protocol to realize data interconnection between the new‑generation System800xA AC800M system and old‑style Advant Controller 400, MasterPiece200/1 legacy 

DCS equipment. Equipped with high‑density 15‑pin D‑sub connector, it supports network redundancy, clock synchronization and hot‑swap maintenance, widely deployed inside chemical‑plant, 

thermal‑power, water‑treatment and metallurgy hybrid‑upgrade automation cabinets.
