FOXBORO FCP280 RH924YA Schneider Electric Field Control Processor

Product Description

Overview

The FCP280 (RH924YA) is a high-capacity, field-mounted control module engineered for the Foxboro I/A Series and EcoStruxure Foxboro DCS platforms. Acting as the primary controller at the field level, it integrates process control, data acquisition, and alarm management while providing seamless communication with field devices and the plant control network. Compared to its predecessor, the FCP270, this module offers substantially higher performance, expanded memory, and advanced redundancy features.

Key Features

• High-reliability operation with single or redundant configurations featuring automatic failover

• High-speed RISC processor for complex control algorithms and extensive databases

• Flexible mounting compatible with DIN-rail and legacy 1x8 baseplates

• Hardened firmware with cybersecurity measures to prevent unauthorized access

• Advanced regulatory, logic, timing, and sequential control support

Communication Pathways

The FCP280 operates as a central hub:

• Upstream: Connects to the Mesh Network for workstations, historians, and other FCP modules

• Downstream: Interfaces with Fieldbus Modules (FBMs) which connect directly to sensors and actuators

Part Number Variants

• RH924YA: Standard FCP280 module

• RH924YB: Redundant pair or bundle variant

• RH924WA: Associated SCD5200 module or baseplate-specific version

Migration Notes

Upgrading from the FCP270 to FCP280 (RH924YA) is largely plug-and-play, but full feature support requires Foxboro I/A Series v8.8 or higher or EcoStruxure Foxboro DCS with Control Core Services v9.0 or later.
