Built‑in function

FBM216 redundant‑ready HART analog input module serves as hot‑standby backup partner for FBM214 in Foxboro I/A‑Series DCS critical‑loop applications. It acquires 4‑20mA analog process values and HART digital diagnostic parameters from field smart transmitters. Group‑isolation architecture improves anti‑interference performance for field signals. When deployed as FBM214/FBM216 redundant pair,automatic module switch‑over occurs upon primary module fault without process‑loop interruption. Hot‑swap supports online module replacement without system shutdown,widely applied for pressure,tank‑level and flow‑critical‑loop maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM216 belongs to Foxboro I/A Series legacy DCS redundant‑ready‑HART‑analog‑input spare‑part family,obsolete original baseplate‑mount redundant‑pair HART‑communication‑input‑interface module component. Must be used in adjacent‑slot redundant‑pair configuration with FBM214 and matched termination hardware. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
