Built‑in function

FBM07A/12A discrete input module collects on‑off status signals of field equipment for Foxboro I/A‑Series DCS system. It cooperates with 12‑style termination assembly to complete field‑side wiring connection. Built‑in filter circuit restrains contact‑bounce interference. Hot‑swap supports online module replacement,widely applied for pump,valve interlock‑signal acquisition loops in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM07A/12A belongs to Foxboro I/A Series legacy DCS discrete‑input spare‑part family,obsolete original baseplate‑mount discrete input module component. Must match with corresponding FBM baseplate and 12‑series termination assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
