ABB BC810K02 module 3BSE031155R1 Brand

Technical Specifications

• Function: Used to extend the CEX-Bus (Communication Expansion Bus) of AC 800M controllers, allowing the connection of additional communication modules.

• Sectioning Capability: Splits the CEX-Bus into two independent, isolated segments. This ensures that a fault or short circuit on one segment does not bring down the entire communication bus.

• Hot Swap Support: Supports online replacement (hot-swapping) of connected communication modules on the extended segment without interrupting the main controller operations.

• Power Supply: Provides logic power isolation and monitoring across the bus segments.

• Kit Components: Includes the BC810 interconnect module and its corresponding baseplate/termination unit.

Target Industries

The BC810K02 is utilized in high-demand, large-scale industrial automation environments where system expansion and high availability are essential:

• Power Generation & Utilities: Nuclear, thermal, and hydro power plants, as well as large electrical substations.

• Oil & Gas / Petrochemical: Upstream production platforms, downstream refineries, and extensive pipeline networks.

• Chemical Manufacturing: Facilities managing complex, continuous chemical reactions requiring massive amounts of field instrumentation.

• Pulp & Paper: Large mills with highly distributed control architectures and extensive I/O demands.

• Mining & Metals: Mineral processing plants, smelting facilities, and automated material handling networks.

Usage Scenarios

• Controller Slot Expansion: Used when an AC 800M controller requires more communication interfaces (such as PROFIBUS, Modbus, or Ethernet modules) than the standard onboard CEX-Bus slots can accommodate.

• Fault Isolation and Risk Mitigation: Segmenting a critical control system’s communication bus so that non-critical or high-risk communication networks (e.g., lines running to remote areas prone to interference) are isolated from core system communications.

• High-Availability System Upgrades: Integrating new field networks into an operating plant, allowing engineers to add, configure, or maintain communication modules on the secondary bus segment without shutting down the primary process controller.

• Distributed Control Room Layouts: Assisting in the neat organization and modular separation of different communication protocols within large, multi-cabinet control enclosures.
