Description
As a single-unit CEX bus interconnection kit released by ABB, BC810K01 (3BSE031154R1) differs from the dual-unit BC810K02. It delivers all ready-to-use accessories for single-side bus segmentation, requiring no additional parts for on-site deployment. It is developed to solve communication overload and fault diffusion risks on long CEX backplane buses in AC800M control racks. Original integrated CEX buses carry all backplane communication data for CPU controllers and CI-series communication modules, where single-point faults such as short circuits and signal attenuation can trigger offline failures of the entire rack. This module isolates faulty segments physically to ensure normal data transmission of other independent bus segments.
It adopts a split dual-layer hardware structure. The TP857 base undertakes mechanical fixing, equipotential grounding, CEX signal wiring and external power access. Built-in overcurrent fuses and anti-reverse diodes eliminate power surge damage to backplane chips. The upper logic main board integrates 3.3V voltage conversion circuits, high-speed CEX bus drivers and autonomous fault diagnosis circuits, which ensure low-delay cross-segment data forwarding without signal distortion. All maintenance operations support hot swapping, allowing technicians to replace faulty modules without cutting off rack power or suspending production processes.
Front-panel multi-color LEDs provide intuitive fault locating for abnormal power supply, link interruption and bus conflict. Complying with international industrial EMC standards, it resists electromagnetic interference from on-site inverters and high-power motors. Compatible with mainstream AC800M controllers including PM861, PM865 and PM866, it is widely applied in medium and small-scale process industries such as water treatment, central heating and fine chemical plants with non-24/7 full-redundancy requirements to optimize backplane communication load and improve long-term system operation stability.
