Description
1. Product Title
Foxboro FBM237 P0914XS‑ 8‑Channel Channel‑Isolated Analog Output Module, I/A‑Series Compact 200 DCS
2. Product Overview
P0914XS (FBM237) is Compact200 8‑channel channel‑isolated analog output fieldbus module for Foxboro I/A‑Series DCS. It converts digital control values into 0‑20 mA analog modulating signals for valve positioners and field final control elements. Every channel provides independent galvanic isolation to eliminate ground‑loop interference. Supports HART pass‑through for HART smart field instruments. Hot‑swappable design allows online module replacement without rack power‑down. Front‑panel LED indicators show module health status. Matched with dedicated compression‑style termination assembly for field wiring. Original manufacturing discontinued, used as spare‑part replacement for petrochemical, chemical and power‑plant legacy DCS racks.
