Product Overview

The ABB BCU-22 (order number 3AUA0000110431) is a control unit intended for converter and drive system architectures that use fiber-optic links for fast, noise-immune communication between the main controller and power/converter modules. In a typical installation, the unit coordinates control and monitoring signals across multiple optical channels, supporting stable operation of multi-module converter arrangements and simplifying diagnostics during commissioning and maintenance.

The BCU-22 is commonly specified where galvanic separation and EMC resistance are required, since optical communication reduces susceptibility to electrical interference inside high-power cabinets.

Technical correction note
The source text contains several unverified or conflicting items (e.g., “IEC 61850 digital substation” functions, inconsistent weights, and “Ethernet router” as a service). These have been removed. The listing values below follow the provided datasheet header.
