Foxboro FBM204 RH914SY Channel-Isolated I/O Module – Product Description

Description / Overview

The Foxboro FBM204 RH914SY is a channel-isolated analog I/O module designed for the EcoStruxure Foxboro DCS (formerly I/A Series). It handles 0–20 mA input and output signals and supports individual channel configuration for flexible field integration. Moreover, it provides stable performance in demanding environments, helping operators maintain accurate process control across complex industrial systems. Its robust electrical isolation protects the control network from noise, grounding issues, and unexpected surges.
