Built‑in function

FBM215 compact HART analog output module converts DCS control commands to 4‑20mA output current for field HART valve positioners and current‑input actuators for Foxboro I/A‑Series DCS system. It adopts true per‑channel galvanic‑isolation architecture to eliminate cross‑channel ground‑loop interference. Independent per‑channel HART modem realizes bidirectional parameter reading‑writing and diagnosis for HART field devices without extra external multiplexer. Output‑loop fault detection quickly identifies open‑circuit and short‑circuit wiring conditions. Hot‑swap supports online module replacement without system shutdown,widely applied for valve‑position‑control‑loop maintenance in petrochemical,chemical and power‑plant facilities

Product Brief

FBM215(P0922VU) belongs to Foxboro I/A Series legacy DCS compact‑200‑series‑per‑channel‑isolated‑HART‑analog‑output spare‑part family,obsolete original compact‑form‑factor 8‑channel HART‑communication‑output‑interface module component. Must match with Compact‑200‑series dedicated baseplate and matched termination assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
