Overview

The Foxboro RH916FK is a Field Control Processor (FCP) module designed for use in the EcoStruxure™ Foxboro Distributed Control System (DCS). It performs a wide range of control functions, including regulatory, logic, timing, sequential control, as well as data acquisition and alarm detection. The module interfaces with Foxboro Fieldbus Modules (FBMs) to collect data from field devices, process it, and manage alarms for safe and efficient operation.

The RH916FK is designed for fault-tolerant operation, where a single module can run independently, but two modules can be paired for redundant configurations, ensuring high availability in safety-critical systems.
