3BSE031154R1 BC810K01: BC810K01 expansion planning: CEX-bus placement and controller support
BC810K01 (3BSE031154R1) is an ABB AC 800M CEX-bus interconnection package. ABB documentation describes BC810 as a CEX-bus interconnection unit for supported processor units. It is a system-expansion component, not an independent controller or an I/O signal module; compatibility depends on the processor model, revision and CEX-bus layout.
Key technical data
| Technical item | Verified value / selection note |
|---|---|
| ABB order code | 3BSE031154R1 |
| Package designation | BC810K01 |
| Core device | BC810 CEX-bus interconnection unit |
| System role | Extends the CEX-bus arrangement for supported AC 800M controllers |
| Supported controller families | PM858/PM861A/PM862/PM864A/PM866/PM866A/PM891 subject to exact revision |
| Installation | Mounting, cable and bus topology are system-specific |
Match the exact ABB designation, system role, electrical limits, approved accessories and revision. Do not infer interchangeability from appearance or a shared family prefix.
BC810K01 is relevant when an AC 800M installation requires additional supported CEX-bus connectivity. Planning should account for the actual controller, connected communication or expansion units, bus loading, cable lengths and physical placement. A controller-family match does not automatically confirm firmware or hardware compatibility.
Selection and compatibility checks
Before selecting 3BSE031154R1, verify the exact BC810 package contents, target controller list, processor revision, CEX-bus topology and any required interconnection cable. Compare it carefully with BC820 and other BC810 order codes; these can represent different bus features or package contents and should not be treated as interchangeable.
For 3BSE031154R1 BC810K01, establish the equipment boundary before procurement: record the host controller or panel, the connected field device, the installed hardware and firmware revisions, the supply source, the protection method and the required operating sequence. A family-name match is not enough to confirm that 3BSE031154R1 BC810K01 is a compatible replacement. Check all interfaces and accessories against the exact ABB documentation.
Commissioning and acceptance
Install BC810K01 with the controller de-energized and follow ABB's module order and interconnection guidance. Inspect the bus connector and cable route, then check controller diagnostics and every attached unit after power-up. Preserve the original bus map and software configuration as part of the maintenance record.
A practical acceptance record for 3BSE031154R1 BC810K01 should include the nameplate photograph, order code, terminal and connector condition, configuration or setting values, software revision where applicable, test equipment and measured results. If 3BSE031154R1 BC810K01 is installed as part of a larger system, record the system-level response as well as the local device indication.
