Description

ABB BC810K02 High-Reliability CEX-Bus Interconnection Unit for Industrial Automation

 

The BC810K02 is a CEX-Bus interconnection unit designed by ABB for industrial automation systems, specifically engineered to enhance communication reliability and system availability in complex control environments. As part of ABB’s AC800M and S800 I/O platforms, the BC810K02 plays a critical role in dividing CEX-Bus networks into independent segments, reducing single-point failures and supporting seamless integration with CPU modules such as PM857 and PM861A 12.

1. Product Overview

The BC810K02 serves as a backbone for industrial communication, enabling real-time data exchange between control systems and field devices. Its modular design consists of a baseplate (TP857) and a power/logic board, providing robust grounding via the DIN rail and supporting hot-swap capabilities for maintenance-free operations 14. With 24V DC ±10% auto-ranging input and -20°C to +60°C temperature tolerance, the unit ensures stable performance in harsh industrial environments.

 

Key functions include:

 

  • CEX-Bus segmentation: Improves network availability by isolating communication traffic.
  • Redundant communication: Supports dual-channel configurations for mission-critical applications.
  • Online replacement: Allows CPU baseplate replacement without disrupting CEX-Bus traffic in fully redundant systems 2.

6. Selection Recommendations

  • System Size: Pair with AC800M CPU modules for large-scale industrial systems; use S800 I/O for smaller applications.
  • Redundancy Needs: Opt for BC810K02-D (dual-channel) for nuclear or offshore projects requiring SIL 2 certification.
  • Environment: Choose BC810K02-H (IP65-rated) for outdoor or washdown environments.

7. Installation & Maintenance Notes

  • Wiring: Use shielded cables (AWG 22–18) for signal integrity; terminate with M12 connectors.
  • Cooling: Maintain 10mm airflow clearance; add fans for ambient temperatures >50°C.
  • Firmware: Update quarterly via ABB’s Automation Builder to access predictive maintenance features.
  • Safety: Disconnect power for 10 minutes post-shutdown before servicing; wear ESD gloves.
