Description
The ABB CI855K01 3BSE018106R1 is a MasterBus 300 (MB300) communication interface module designed for ABB AC 800M controllers within the System 800xA automation platform. It provides communication between modern AC 800M controller systems and existing ABB Advant OCS / MB300-based control systems, allowing integration of legacy installations without complete system replacement.
The CI855K01 package includes the CI855 MB300 Interface Module and TP853 baseplate. It connects to the AC 800M controller through the CEX-Bus and supports MB300 master communication, network redundancy, clock synchronization, dataset communication, hot swap capability, and peer-to-peer data exchange.
This module is commonly used in process industries, power generation plants, marine automation systems, and industrial facilities where ABB Advant Controller 410/450, MasterPiece 200/1, or other MB300-based systems need to communicate with newer AC 800M and System 800xA platforms.
