Built‑in function

FBM217 high‑density discrete input module converts field contact and switch status signals into digital process data for Foxboro I/A‑Series DCS system. It adopts group‑isolation architecture,signal conditioning and optical isolation are implemented on matched termination assembly. It supports pulse counting and SOE sequence‑of‑events timestamp recording for accident analysis. It can run as single‑point collection or form hot‑standby redundant pair with another FBM217. Hot‑swap supports online module replacement without system shutdown,widely applied for valve feedback,motor status and interlock‑logic‑loop maintenance in petrochemical,chemical and power‑plant facilities

Product Brief

FBM217(P0914TR) belongs to Foxboro I/A Series legacy DCS Compact‑200‑series high‑density‑discrete‑input spare‑part family,obsolete original compact‑form‑factor 32‑channel group‑isolated discrete‑input module component. Must match with Compact‑200‑series dedicated baseplate and corresponding termination assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
