ABB BC810K02-3BSE031155R1
Overview
The ABB BC810K02 is a CEX-Bus interconnection unit for the ABB AC 800M controller family, with ordering number 3BSE031155R1. It provides the physical and electrical interface between an AC 800M controller and its CEX-Bus connected I/O, combining the baseplate and power supply/logic board in a single DIN-rail mounted unit.
Hot swap is supported, allowing the interconnection board to be replaced without disturbing the controller, which is essential for maintaining control system availability in process plants.
Engineering & Design
The BC810 unit consists of two basic parts: the baseplate (TP857) and the power supply/logic board. The baseplate carries the connectors for the CEX-Bus and external power, and is grounded to the DIN-rail through the metal parts of the housing. It also carries the external power voting diode and fuse for protection.
The power supply and logic board contain the +3.3 V converter, logic circuits, and drivers for the CEX-Bus interconnection, plus the connector for the interconnection cable to other units. The BC810K02 is compatible with PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A, PM867, and PM891 controllers.

For ABB control system availability, the ABB BC810K02 CEX-Bus interconnection unit is the link that keeps I/O communicating, and Seven Star LLC supplies the ABB BC810K02 with verified part numbers for 800xA projects.
Why Seven Star LLC
Seven Star LLC supplies the ABB BC810K02 CEX-Bus interconnection unit for ABB control system projects across the Gulf, with verified part numbers and technical documentation. Our team assists with controller compatibility checks and spares planning for ABB 800xA installations.
We support oil and gas, power, and process industries with reliable B2B automation spares supply throughout the GCC.
Maintainability
The hot-swap capability of the BC810K02 is central to its design value: when an interconnection board must be replaced, the controller continues operating, protecting production availability. The baseplate carries the power voting diode and fuse, protecting the unit from supply faults.
Compatibility with the PM857 through PM891 controller range means the same spare part serves multiple controller generations, simplifying spare stock and maintenance procedures across a plant’s ABB fleet.
Documentation & Supply
Seven Star LLC supplies the ABB BC810K02 with full technical documentation and controller compatibility checks, supporting your ABB 800xA maintenance programme.
We also provide other ABB automation spares and can support hardware refresh projects across the GCC.
The BC810K02 is often stocked as a strategic spare because the interconnection unit is a single point in the AC 800M architecture. Its compatibility across the PM857 to PM891 range means one stocked unit protects multiple controller types, and the documented hot-swap procedure keeps replacement time to a minimum.
The documented spare part strategy for ABB 800xA systems commonly includes the BC810K02, and our team can help define the right sparing level for your plant.
The 800xA system documentation covers the BC810K02 installation and replacement procedure, and our team can provide guidance on the related hardware for your specific controller model.
The grounding of the housing to the DIN-rail is part of the EMC design, and correct installation following the ABB guidance maintains the unit’s immunity performance.
The BC810K02 is a compact DIN-rail unit, and its standardised connectors match the CEX-Bus cabling used across the AC 800M family.
For ABB 800xA maintenance, the ABB BC810K02 CEX-Bus interconnection unit is the key spare, and sourcing the ABB BC810K02 CEX-Bus interconnection unit from Seven Star LLC ensures verified part numbers for the ABB BC810K02 CEX-Bus interconnection unit in your stock.
