Product Description

Product Overview

The ABB BC810K02 3BSE031155R1 is a dedicated CEX Bus Interconnection Unit Kit designed for ABB AC 800K / AC 800M distributed control systems. It expands controller communication interfaces, supports redundant bus architecture, and enables hot-swappable module replacement to help maintain continuous system operation.

This unit is suitable for process automation, power plants, chemical plants, oil & gas facilities, water treatment systems, and other industrial environments where reliable DCS communication is critical.

Key Features

CEX bus expansion — Extends communication interfaces for ABB AC 800K / AC 800M controllers.
Redundant bus support — Helps build ring/redundant network topologies to improve communication reliability.
Hot-swappable design — Supports module replacement and CPU online replacement without full system shutdown in applicable configurations.
Industrial-grade reliability — Designed for continuous operation under demanding industrial conditions.
Status indication — Equipped with LEDs for power, communication, and module status monitoring.
Strong anti-interference capability — Supports stable operation in environments with electromagnetic noise and complex wiring.

Typical Applications

DCS system communication expansion in process industries
Redundant bus network construction for AC 800K / AC 800M controllers
Power generation, petrochemical, oil & gas, and water treatment plants
System upgrades where bus redundancy and hot-swap maintenance are required
Industrial automation projects requiring stable controller-to-I/O communication
