ABB BC810K01 3BSE03115R1 CEX-Bus Interconnection Unit

Overview

The BC810K01 3BSE03115R1 is a dedicated CEX-bus interconnection module developed by ABB for AC 800M control platforms. It is used to segment and stabilize the CEX-bus, ensuring consistent data transmission between controllers and connected communication or I/O expansion units. Supplied as a complete kit, the unit simplifies installation while maintaining system integrity during operation and maintenance.

Functional Characteristics

The BC810K01 acts as a structural and electrical interface within the CEX-bus architecture. By dividing the bus into defined segments, it reduces fault propagation and improves overall communication availability. The design allows bus continuity even when CPUs are replaced or serviced, minimizing downtime in high-availability control systems. Support for redundant configurations makes it suitable for mission-critical automation environments.

FAQ

Can the BC810K01 be replaced while the system is running?
Yes. The unit supports hot swapping, allowing replacement without interrupting CEX-bus communication.

Is the terminator required for correct operation?
Yes. The included TB850 terminator is essential to maintain proper signal integrity on the CEX-bus.

Does this unit add I/O capacity?
No. The BC810K01 provides bus interconnection and segmentation only; it does not function as an I/O module.
