Overview

The Harmony Bridge Controller (BRC-300) is a high-performance, high-capacity process controller designed to seamlessly integrate with both Harmony block I/O and Harmony rack I/O within the Symphony™ Enterprise Management and Control System. This rack-mounted controller is fully compatible with the INFI 90® OPEN system in terms of functionality, communication, and packaging.

The BRC-300 controller is responsible for collecting process I/O, executing control algorithms, and sending control signals to various process-level devices. It also facilitates the import and export of process data between other controllers and system nodes, while accepting control commands from operators and computers connected to the network.
