Built‑in function

FBM211 high‑density 16‑channel analog input module converts field‑transmitter 0‑20mA current signals to digital process data for Foxboro I/A‑Series DCS system. It adopts group‑isolation structure instead of channel‑to‑channel isolation,each eight‑channel forms one isolated group. Sigma‑delta conversion guarantees high‑precision process‑signal acquisition. Open‑circuit detection quickly identifies broken field‑wiring faults. 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

FBM211 belongs to Foxboro I/A Series legacy DCS high‑density‑analog‑input spare‑part family,obsolete original baseplate‑mount 16‑channel group‑isolated analog‑input module component. Must match with corresponding FBM baseplate and matched termination assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
