Built‑in function

FBM07 discrete input module collects on‑off status signals from field switches,relay contacts and equipment auxiliary feedback for Foxboro I/A‑Series DCS system. Built‑in RC filter eliminates contact‑bounce false triggering. Group‑isolation design improves anti‑interference performance in noisy cabinet environment. Hot‑swap supports online module replacement,widely applied for pump,valve and interlock‑logic status‑acquisition loops in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM07 belongs to Foxboro I/A Series legacy DCS discrete‑input spare‑part family,obsolete original baseplate‑mount contact‑sense input 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.
