The BC810 unit consists of two basic parts: baseplate (TP857) and power supply/logic board. The baseplate is where the connectors to CEX-Bus and the external power reside. It is grounded to the DIN-rail through metal parts of the housing. The board also carries the external power voting diode and fuse. The power supply and logic board contain the +3.3 V converter, logic, drivers for CEX-Bus interconnection, and the connector for the interconnection cable. The BC810 can be used with PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A, PM867 and PM891.
In a fully redundant system with two interlinked BC810 and primary/backup CPU pair, the BC810 support online replacement of the CPU baseplate without disturbing the CEX traffic. If the BC810 has to be replaced, all traffic to the connected CEX segment is stopped. The CEX-Bus is used for extending the onboard communication ports with communication interface units. It is also possible to use redundant communication interfaces on the CEX-Bus. The CEX-Bus Interconnection unit BC810 is used to increase the availability of the CEX-Bus by dividing it into separate segments. This improves the availability of systems with redundant communication interfaces.
The BC810K02 3BSE031155R1 ABB CEX-bus Interconnection Unit kit may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Segmented Isolation: It divides the CEX bus into multiple independent electrical segments. Even if one segment fails, the entire communication bus will continue to operate normally.
High Availability and Redundancy: It supports redundant communication interfaces, significantly improving system uptime.
Hot-Swapping: In a fully redundant master/slave configuration, the ABB BC810K02 allows for online replacement of the CPU backplane without interrupting CEX communication.
Controller Compatibility: It is fully compatible with ABB System 800xA series processor models, including PM857, PM861A, PM862, PM864A, PM865, PM866, PM866A, PM867, and PM891.
This device is specifically designed to divide the Communication Expansion Bus (CEX) into independent electrical segments. By isolating different parts of the communication bus, it protects the system from the impact of a network-wide failure. If a communication card or cable segment fails, the BC810 limits the impact to that specific segment, allowing the rest of the control network to operate seamlessly.
