Built‑in function

FBM216 redundant‑ready HART analog input module serves as hot‑standby backup partner for FBM214 within Foxboro I/A‑Series DCS system. It acquires 4‑20mA analog process values and HART digital diagnostic‑parameter data from field smart transmitters. It adopts group‑isolation design rather than per‑channel isolation. When primary FBM214 fails,FBM216 automatically takes over control without loop interruption. Hot‑swap supports online module replacement without system shutdown,widely applied for pressure,tank‑level and flow‑critical‑measurement‑loop maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM216(P0917XQ) belongs to Foxboro I/A Series legacy DCS standard‑200‑series‑redundant‑group‑isolated‑HART‑analog‑input spare‑part family,obsolete original redundant‑ready 8‑channel HART‑communication‑input‑interface module component. Must pair with FBM214 and standard‑200‑series dedicated baseplate and termination assembly. Not interchangeable with Compact‑200‑series FBM216b. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
