Built‑in function

FBM15 discrete I/O expansion module increases available discrete I/O points for Foxboro I/A‑Series DCS system. It is dependent on FBM10 main module and cannot run on its own. It assists in collecting field switch feedback signals and outputting relay‑contact commands for interlock‑logic processing. Hot‑swap supports online module replacement,widely applied for multi‑point interlock‑signal acquisition‑control loops in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM15 belongs to Foxboro I/A Series legacy DCS I/O‑expansion spare‑part family,obsolete original baseplate‑mount auxiliary expansion module component. Must match with corresponding FBM baseplate and FBM10 main module. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
