The SPBRC300 is a microprocessor-based Bridge Controller engineered for the ABB Symphony Plus and Harmony Rack (INFI 90) distributed control systems. Despite frequent mislabeling in third-party catalogs, the SPBRC300 is not a crane controller; it is a full-featured process automation CPU that serves as the execution core of a control loop.
As a member of ABB’s proven BRC (Bridge Controller) family, the SPBRC300 executes complex function block logic, coordinates large volumes of I/O data, and manages deterministic communication between field modules and the plant-wide control network. Its robust architecture and compact rack-mounted design make it ideal for continuous-duty industrial environments where long-term stability and predictable scan times are mandatory.

The SPBRC300 is widely deployed in continuous and batch-oriented industries, including:
Thermal Power Generation – Coordinated control of burners, feedwater, and auxiliary systems
Chemical & Petrochemical Plants – Batch sequencing, interlocks, and advanced PID control
Modernization Projects – Drop-in replacement for BRC100 / BRC200 controllers to increase processing capacity without rewiring I/O
Can the SPBRC300 replace older BRC controllers?
Yes. The SPBRC300 is designed for backward compatibility within Harmony Rack and INFI 90 systems, allowing legacy BRC100/BRC200 units to be upgraded while preserving existing field wiring and rack infrastructure.
Which engineering tools are required?
The controller is configured using ABB Composer or Symphony Plus Engineering (S+) tools. Software compatibility should be confirmed to ensure support for SPBRC300 hardware features.
Does the SPBRC300 support redundancy?
Yes. When installed in a redundant controller mounting base, two SPBRC300 units operate in a primary/backup configuration with automatic, bumpless switchover upon controller failure.
