Built‑in function
FBM09 triac output module converts DCS digital logic command into 120VAC solid‑state switching signal for Foxboro I/A‑Series system. Zero‑cross switching reduces electrical noise interference. Built‑in channel‑level protection prevents triac damage caused by load short‑circuit. Hot‑swap supports online module replacement without system shutdown,widely applied for solenoid‑valve and auxiliary‑relay control‑loop maintenance in petrochemical,chemical and power‑plant facilities.
Product Brief
FBM09 belongs to Foxboro I/A Series legacy DCS discrete‑output spare‑part family,obsolete original baseplate‑mount triac output 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.
