Description
Product Introduction & Engineering Value
A controller can be perfectly healthy while its communication infrastructure becomes the weak point. The ABB BC810K02 (3BSE031155R1) is designed to improve the availability of AC 800M systems by dividing the CEX-Bus into independent segments, allowing redundant communication interfaces to continue operating during maintenance or hardware replacement.
Unlike a standard BC810 module, the BC810K02 is supplied as a complete installation kit, reducing the time required to assemble all required accessories. For engineers maintaining System 800xA installations, this simplifies procurement and helps ensure every component required for commissioning is available from a single package.

Field Application & The “Trench” Experience
During a scheduled maintenance outage at a petrochemical complex, engineers needed to replace the primary CPU baseplate in a redundant AC 800M controller without interrupting field communication. Because the installation already used a BC810K02 kit, the CEX-Bus had been separated into independent segments.
After transferring control to the standby processor, maintenance personnel replaced the hardware while communication modules remained operational. The process unit continued running without an unexpected shutdown, saving several hours of recovery time.
Typical applications include:
- Distributed burner management systems in combined-cycle power plants
- Continuous polymer reactor control using redundant AC 800M controllers
- Refinery process units requiring uninterrupted Ethernet and fieldbus communication
- BC810K02 3BSE031155R1
- BC810K02 3BSE031155R1
Transparency SOP: QA & Testing
Every kit is inspected before shipment through a documented quality process.
- Verify ABB article number and hardware revision.
- Confirm both BC810 interconnection units are included.
- Inspect the TP857 baseplates for connector integrity.
- Verify the TK851 interconnection cable and TB850 CEX-Bus terminators.
- Perform functional power-up verification on compatible AC 800M hardware.
- Package all components in anti-static materials with protective cushioning.
The Veteran’s Tech Trap Guide
⚠️ BC810 and are not identical ordering codes.
BC810 refers to the interconnection unit itself. is the complete kit that includes:
- Two BC810 interconnection units
- Two TP857 baseplates
- One TK851 interconnection cable
- Two TB850 CEX-Bus terminators
Ordering the wrong part number is a common procurement mistake.
⚠️ External 24 VDC power is required.
The does not draw operating power solely from the controller backplane. Verify the external power supply wiring before troubleshooting communication faults.
PRO TIP:
Before replacing a assembly, photograph every CEX-Bus cable and terminator location. Incorrect cable routing is responsible for many commissioning delays after maintenance.
⚠️ Don’t omit the terminators.
Missing or incorrectly installed TB850 CEX-Bus terminators can create intermittent communication errors that resemble controller faults rather than bus configuration problems.
Dynamic FAQ
Q1. What is included with the kit?
The standard kit includes 2 × BC810 interconnection units, 2 × TP857 baseplates, 1 × TK851 interconnection cable, and 2 × TB850 CEX-Bus terminators.
Q2. Can the support online CPU replacement?
Yes. It is designed to support online CPU replacement in redundant AC 800M systems while maintaining CEX-Bus communication.
Q3. Is this kit compatible with System 800xA?
Yes. The is intended for ABB AC 800M controllers used in System 800xA architectures. Compatibility should still be verified against the specific controller model and software release.
Q4. Are New Surplus units genuine ABB products?
Yes. New Surplus inventory consists of unused ABB hardware from original industrial stock. Each kit undergoes identity verification and physical inspection before shipment.
Q5. Does replacing the require application software changes?
Typically, no. The kit serves as a CEX-Bus infrastructure component rather than a controller or communication protocol module. However, hardware configuration should always be validated during commissioning.
Q6. Is warranty available?
Yes. Warranty coverage is available for both New Surplus and professionally Refurbished kits. Warranty terms depend on the supplied condition and are confirmed with the quotation.
