Built‑in function

FBM13 expansion input module increases discrete‑input point quantity for Foxboro I/A‑Series DCS system. It cannot work independently and must cooperate with FBM08 main module. It collects 120VAC on‑off status signals from field‑side equipment contacts. Built‑in filter suppresses contact‑bounce false triggering. Hot‑swap supports online module replacement,widely applied for large‑quantity interlock‑signal acquisition loops in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM13 belongs to Foxboro I/A Series legacy DCS discrete‑input expansion spare‑part family,obsolete original baseplate‑mount expansion input module component. Must match with corresponding FBM baseplate and FBM08 main module. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
