Overview

The ABB BCU-02 3AUA0000110429 Control Unit is an advanced control solution designed for managing converters through fiber optic communication. This versatile unit supports high-performance ABB drive systems and features integrated branching unit functionality for real-time data collection. It efficiently stores operational data on an SDHC memory card, allowing ABB service teams to analyze this data for diagnostics and system optimization.

Functional Highlights

The BCU-02 is equipped with two fiber optic ports (V1 and V2) that facilitate direct connections to converter modules, streamlining system integration and monitoring. It is engineered with flexibility in mind, featuring three option slots for I/O extensions, encoder interfaces, and fieldbus adapters. This modular approach enhances the unit's adaptability to varied applications.

Moreover, the control unit includes a removable memory unit, which simplifies maintenance and replacement procedures. Settings can be easily retained by transferring the memory module to a new unit, minimizing downtime. The BCU-02 also supports drive-to-drive (XD2D) communication via an RS-485 link, making it particularly useful for multi-drive configurations.

To ensure robust communication, the BCU-02 is compatible with both 1 mm plastic optical fiber cables (up to 35 m) and 200 μm hard-clad silica fiber cables (up to 100 m). It is crucial that the fiber lengths connected to a single control unit are equal to avoid signal delays, ensuring synchronized operation across the system.

Built for industrial environments, the unit operates on 24 V DC and consumes approximately 300 mA. It withstands ambient temperatures ranging from -10°C to +55°C, with storage tolerances from -40°C to +70°C. The BCU-02 also supports humidity levels from 5% to 95% non-condensing, making it well-suited for harsh conditions.
