Product Overview

The ABB BC810K01 is a CEX-Bus interconnection unit designed to improve system availability and enable redundancy in ABB control systems. It is composed of two main parts: the baseplate (TP857) and the power supply/logic board.

The baseplate includes connectors for the CEX-Bus and external power input and is grounded through its metal housing to the DIN rail. It also incorporates a power voting diode and a fuse. The power supply and logic board includes a +3.3 V converter, control logic, drivers for CEX-Bus communication, and a connector for the interconnection cable.

The BC810 is compatible with the following CPUs: PM861A, PM862, PM864A, PM865, PM866, PM866A, and PM867.

Key Features

• Enables redundant communication interface units

• Supports on-line replacement of CPU baseplates without disturbing CEX traffic

• External power supply support

• Hot-swappable design

Application & Benefits

The BC810 is used to divide the CEX-Bus into separate segments, enhancing system reliability by isolating failures and supporting redundant configurations. In systems with dual BC810 units and a redundant CPU setup, it allows online replacement of the CPU baseplate. However, replacing the BC810 itself will interrupt CEX segment communication.

The CEX-Bus is primarily used for expanding onboard communication ports through interface units, and it supports the implementation of redundant communication links, ensuring maximum system uptime and performance.
