ABB CI855K01 Communication Interface 3BSE018106R1 MB300 PROFIBUS DP

Product ID: CI855K01

Order Number: 3BSE018106R1

Type: Communication Interface Module

Manufacturer: ABB (Sweden/Switzerland)

Category: DCS / PLC / AC 800M Communication Module

Product Overview: Dual-Protocol Gateway for System Migration

The ABB CI855K01 is a high-performance communication interface module designed for the AC 800M controller family. It serves as a critical gateway, providing dual communication capabilities that are essential for plant modernization projects.

The module's primary distinction is its support for two industrial protocols :

MasterBus 300 (MB300): Enables direct connectivity with legacy ABB Advant Controller 400 series and Master systems, allowing seamless integration of older equipment into new System 800xA environments .

PROFIBUS DP: Functions as a Class 1 master, connecting up to 124 PROFIBUS DP slave devices, including remote I/O, drives, sensors, and actuators .

This dual-protocol support makes the CI855K01 the ideal solution for plants transitioning from Advant OCS platforms to modern AC 800M control architecture while preserving existing fieldbus investments.

Key Features & Benefits

Dual-Protocol Engine: Supports MB300 (for legacy ABB systems) and PROFIBUS DP V1 (for industrial field devices) in a single module .

Legacy System Integration: Provides point-to-point communication between AC 800M and Advant Controller 400/450 or MasterPiece 200 controllers via MB300 .

High-Density PROFIBUS Network: Master capability for up to 124 PROFIBUS DP slaves, enabling extensive I/O and drive networks .

Network Redundancy Support: Supports redundant MB300 network configurations and PROFIBUS DP redundant lines; automatic failover ensures maximum system availability .

Hot Swappable: Module can be replaced without powering down the system, minimizing downtime during maintenance .

CEX-Bus Powered: Powered directly via the CEX-Bus through the TP855 baseplate; no external power supply required .
