Built‑in function
E69F‑BI2‑S I/P converter converts DCS 4‑20mA analog control signal into proportional pneumatic pressure output to actuate field pneumatic control valves. It supports direct or reverse action setup for different process requirements. Rugged weather‑proof housing adapts to outdoor and harsh field‑site environment,widely applied for pneumatic valve drive loops in petrochemical,chemical and power‑plant facilities.
Product Brief
E69F‑BI2‑S belongs to Foxboro legacy process‑transducer spare‑part family,obsolete original field‑mount I/P converter component. Widely used for original Foxboro system equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
