Built‑in function

FBM09B/14B triac output module converts DCS digital logic commands to 120VAC solid‑state switching signals. It cooperates with 14B‑style termination assembly to complete field‑side signal wiring. Zero‑cross switching reduces electrical noise interference inside instrument cabinet. 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

FBM09B/14B 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 and 14B‑series termination assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
