Foxboro FCP280 RH924WA Field Control Processor Module

Description

The Foxboro FCP280 RH924WA Field Control Processor Module is a distributed, optionally fault-tolerant, field-mounted controller module designed for process control and alarming functions. Operating within the Foxboro Evo Process Automation System, the device executes regulatory, logic, timing, and sequential control schemes in conjunction with connected Fieldbus Modules (FBMs), while also managing data acquisition, alarm detection, and notification tasks. The Foxboro FCP280 connects to The Mesh control network via standard fiber optic or copper 100 Mbps Ethernet cables from baseplate-mounted network adapters. In this specific hardware configuration, the RH924WA fiber adapter equips the module with ceramic LC connectors to interface via multimode fiber optic cabling.

The module interfaces with up to 128 Compact or standard 200 Series FBMs via a 2 Mbps HDLC fieldbus across four PIO channels (Expanded fieldbus). Alternatively, it supports up to 64 100 Series FBMs on a 268 Kbps HDLC fieldbus, with the remaining allocation made up of 200 Series modules up to the 128-module limit. Built with a rugged, non-vented die cast aluminum housing, the device is rated for Class G3 harsh environments and certified for field mounting in industrial process automation applications.

Installation Guidelines

• Baseplate Mounting: Mount the FCP280 in dedicated, keyed slots on vertical (RH924YF) or horizontal (RH924YL) DIN rail baseplates. Vertical baseplates are recommended for optimized convection cooling.
• Fault-Tolerant Setup: Install fault-tolerant module pairs in adjacent FCP280 slots on the baseplate to enable direct internal interconnecting communication.
• Network Cabling: Connect the RH924WA fiber adapter to The Mesh Ethernet switches using 62.5/125 um multimode fiber optic cables up to a maximum distance of 2 km.
• Fieldbus Wiring: Ensure each Fieldbus port on the baseplate is dedicated exclusively to either a 2 Mbps HDLC fieldbus (200 Series) or 268 Kbps HDLC fieldbus (100 Series). The cable length for each Expanded fieldbus segment must not exceed 60 m without isolation/extension devices.
