Foxboro RH924UQ FCP280 Field Control Processor

Product Description

The RH924UQ is the Foxboro FCP280 field control processor for I/A Series DCS system. It executes real-time control algorithms, closed-loop regulation, sequence logic and data communication, and works together with FBM series I/O modules to collect field signals and output control commands. It is the core processing unit for Foxboro I/A Series distributed control platform, widely used in petrochemical, power and refining process control systems.
