Built‑in function

CM400YN FBM12 discrete input module collects on‑site switch,valve auxiliary contact and interlock feedback signals. Opto‑electrical isolation suppresses ground‑loop interference and noise from industrial field environment. Configurable input filter eliminates contact‑bounce interference. It transmits digital status data to I/A‑Series controller through fieldbus baseplate. Hot‑swap function supports online module replacement to reduce plant downtime risk. Independent per‑channel LED facilitates quick on‑site signal inspection,widely applied for valve feedback,alarm and safety‑interlock signal acquisition loops in petrochemical,chemical and power‑plant facilities.

Product Brief

CM400YN belongs to Foxboro I/A Series legacy DCS spare‑part family,obsolete original automation component. It must be matched with corresponding I/A‑Series FBM baseplate and complete correct field DC‑signal wiring. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.今天 16:14
