Built‑in function

FBM17D mixed I/O module integrates analog signal acquisition,dry‑contact switch‑status monitoring and analog control output for Foxboro I/A‑Series DCS system. Group‑isolated design improves anti‑interference performance inside instrument cabinet. Open‑circuit fault detection helps locate field‑side wiring faults rapidly. Hot‑swap supports online module replacement without system shutdown,widely applied for multi‑parameter measurement‑and‑control‑loop maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM17D belongs to Foxboro I/A Series legacy DCS mixed‑I/O spare‑part family,obsolete original baseplate‑mount mixed analog‑discrete‑I/O 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.
