Schneider Electric RH924YA (FCP280) – Field Control Processor 280 | Foxboro I/A Series DCS Platform
Engineering Background: The FCP280 (Field Control Processor 280) is a high-performance DCS controller developed under the Foxboro I/A Series architecture, now part of the Schneider Electric Foxboro portfolio. Designed for continuous process industries, it serves as the primary execution engine for control strategies in refining, petrochemical, power generation, and pharmaceutical environments.
Product Positioning: The RH924YA is the hardware assembly identifier for the FCP280 module. It delivers deterministic scan-cycle execution, redundancy-ready architecture, and native integration with the Foxboro I/A Series fieldbus and I/O subsystems — making it the preferred choice for procurement engineers upgrading or maintaining legacy Foxboro DCS installations.

- Long Service Life: Engineered for 24/7 continuous operation in harsh industrial environments
System Architecture & Signal Flow
The FCP280 resides in the Foxboro I/A Series control network, communicating upstream to the operator workstation via the Nodebus and downstream to field I/O via Fieldbus Module Bases (FBMs). Control strategies (compound/block logic) are downloaded from the Foxboro AIM historian or IA Series workstation and executed locally on the FCP280, ensuring control continuity even during network interruptions. Redundant FCP pairs perform bumpless switchover in the event of a primary processor fault.

Technical FAQ
Q: Is the RH924YA compatible with my existing Foxboro I/A Series system?
A: Yes. The FCP280 (RH924YA) is designed for direct integration into Foxboro I/A Series DCS architectures. Confirm your system software revision with our engineers before ordering.
Q: Can this module operate in a redundant configuration?
A: Yes. The FCP280 supports 1:1 redundancy. A second RH924YA unit is required for the redundant pair.
Q: What firmware version is installed?
A: Firmware version is documented per unit. Contact us with your system’s IA Series software version for compatibility confirmation.
Q: Do you provide a test report or inspection certificate?
A: Yes. Functional test reports are available upon request for OEM and EPC procurement requirements.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume pricing available for orders of 3+ units.
