BC810K01 3BSE031154R1 MODULE

Model Overview: BC810K01 (Part Number: 3BSE031154R1)

The ABB BC810K01 (Part Number: 3BSE031154R1) is a specialized CEX-Bus Interconnection Unit Kit engineered for ABB AC 800M controller platforms.

The main purpose of the BC810 unit is to segment and extend the CEX-Bus (Communication Expansion Bus). By dividing the CEX-Bus into independent electrical segments, it isolates communication faults, allows online replacement (hot swapping) of central processing units (CPUs) without interrupting bus traffic, and enhances overall control system availability.

The BC810K01 kit consists of three core components:

• BC810: Interconnection Unit / Logic Board Module

• TP857: Module Baseplate (60 mm width)

• TB850: CEX-Bus Terminator

Operating Industries

The BC810K01 interconnection unit is deployed in high-availability process industries using ABB System 800xA where system downtime presents major operational or safety risks:

• Power Generation & Distribution: Thermal, nuclear, hydroelectric, and combined-cycle power facilities.

• Oil & Gas: Upstream platforms, gas processing facilities, pipeline compressor stations, and refineries.

• Chemical & Petrochemical: Continuous process chemical manufacturing and polymer reaction plants.

• Pulp & Paper: Automated paper machines, chemical recovery boilers, and pulping lines.

• Metals & Mining: Smelters, mineral processing facilities, and continuous casting systems.

• Water & Wastewater: Large municipal water purification and automated distribution plants.

Common Usage Scenarios

1. CEX-Bus Segmentation and Protection

   Dividing the CEX-Bus into separate physical segments so that an electrical fault or short circuit on one communication module does not crash the entire controller bus network.

2. High-Availability Redundant CPU Configurations

   Interlinking primary and backup AC 800M CPUs to allow seamless failover and support online replacement of a CPU baseplate while maintaining continuous CEX-Bus data traffic.

3. Communication Interface Expansion

   Connecting multiple communication expansion interfaces (such as PROFIBUS DP, PROFINET, Modbus TCP, or Ethernet modules) to an AC 800M controller platform without degrading bus signals.

4. Maintenance and Live System Servicing

   Facilitating hot-swappable module maintenance during continuous plant operation, preventing unnecessary shutdown cycles during hardware servicing.
