Product Details

The CI855K01 3BSE018106R1 is high‑speed MasterBus300 Comms Module for ABB AC800M DCS platform, it serves as reliable AC800M MB300 Fieldbus Unit. The complete set includes CI855 communication board and matching TP853 baseplate.

This module adopts ABB proprietary MasterBus300 high‑speed fieldbus protocol, it features fast dataset transmission capability. It connects to AC800M main CPU via CEX‑Bus backplane bus, completes cyclic process data interaction between controller and MasterBus300 field equipment. Hot‑swap function allows module replacement without powering off the control rack, effectively reduces system maintenance downtime. The fieldbus port adopts galvanic isolation design to improve anti‑interference performance in complex industrial environment.

Front‑panel LED indicators display power supply status, CEX‑Bus link and MasterBus300 bus communication condition. Built‑in hardware self‑diagnosis can detect bus interruption, short‑circuit and module internal hardware faults, fault alarm information can be uploaded to DCS operator station. Industrial‑grade circuit design meets strict EMC requirements of heavy‑industry control cabinet.

Standard DIN rail rack‑slot mechanical structure, can be installed together with CPU and other communication modules in one control rack. Widely applied in thermal power, petrochemical, pulp‑paper and metallurgy industries. It is essential communication hardware for MasterBus300 network reconstruction, field device access and defective communication module replacement for legacy AC800M automation projects.
