Built‑in function

FBM17A high‑level analog input module converts field‑side transmitter analog signals into digital data for Foxboro I/A‑Series DCS system. It is an enhanced variant of FBM17 with upgraded channel diagnostic capability. Channel‑by‑channel isolation effectively eliminates ground‑loop interference. Open‑circuit detection helps identify broken field‑wiring faults rapidly. Hot‑swap supports online module replacement without system shutdown,widely applied for pressure,tank‑level and flow‑measurement‑loop maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM17A belongs to Foxboro I/A Series legacy DCS analog‑input spare‑part family,obsolete original baseplate‑mount high‑level analog‑input module component. Must match with corresponding FBM baseplate assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
