1. Product Title
Foxboro FBM201 RH914SQ‑ 8‑Channel Channel‑Isolated Analog Input Module for I/A Series DCS
2. Product Overview
The RH914SQ (FBM201) is Foxboro I/A‑Series Compact 200 I/O fieldbus module, collecting multi‑type analog field signals and converting to digital data for DCS controller processing. Every channel provides full channel‑to‑channel galvanic isolation, suppressing ground‑loop interference from transmitters. Supports HART pass‑through for HART smart transmitter configuration and diagnostics. Hot‑swappable without system shutdown. Front‑panel LED indicates module operational status. Widely used as spare replacement for existing Foxboro I/A‑Series racks in chemical, refinery and power‑generation plants.
