Built‑in function

AD207AV analog isolator module provides electrical galvanic isolation between field‑side analog loops and Spec‑200 instrument rack backplane circuit. It effectively eliminates measurement deviation caused by ground‑loop interference in complex industrial sites. Shielded metal structure restrains electromagnetic interference,ensures accurate transmission of pressure,flow and temperature analog signals. LED status indicators help field technicians quickly identify power and module abnormal conditions for on‑site troubleshooting,widely applied for chemical,petrochemical and power‑plant continuous‑running control loops.

Product Brief

AD207AV belongs to Foxboro Spec‑200 legacy DCS spare‑part family,obsolete original plug‑in automation component. Must be fitted inside matching Spec‑200 instrument rack with proper field analog wiring. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation
