Product details

Product Overview

ABB BC810 3BSE031155R1 (BC810K02) is a CEX-Bus Interconnection Unit. It increases CEX-Bus availability by dividing it into separate segments. The unit consists of TP857 baseplate and power supply/logic board. Baseplate holds CEX-Bus connectors, external power connections, voting diode and fuse. Logic board contains +3.3 V converter, drivers, and interconnection cable connector. Supports redundant communication interfaces and online CPU replacement. Hot swap capable.

Frequently Asked Questions

Q: What is the purpose of BC810 in a control system?
BC810 segments the CEX-Bus to improve availability. It allows redundant communication interfaces and online CPU replacement without disrupting CEX traffic.
Q: Can I replace BC810 while system is running?
No. If BC810 itself is replaced, all traffic to that CEX segment stops. However, CPU baseplate replacement is online without disturbance.
Q: Which CPUs work with BC810?
BC810 works with PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A, PM867, and PM891. Check compatibility for your specific CPU.
Q: What does the BC810K02 package include?
It includes TP857 baseplate and the power supply/logic board. Baseplate has CEX-Bus connectors, power terminals, voting diode and fuse.
Q: Is BC810 suitable for hazardous areas?
Yes. It has cULus Class 1 Zone 2, AEx nA IIC T4, and Ex nA IIC T4Gc X certification for hazardous locations.
Selection tip: Use BC810 in redundant systems with PM86x/PM89x CPUs. It enables true high integrity by segmenting CEX-Bus and supporting hot swap.
Experience note: Always mount BC810 on grounded DIN rail. The metal housing provides grounding – ensure good contact for safety and EMC performance.
