FOXBORO E69F-BI7-JS UNMP Smart Pneumatic Positioner Module

📦Product Overview

The FOXBORO E69F-BI7-JS 19–23PSI UNMP is a pneumatic positioner module used in Foxboro I/A Series control systems.This device functions as an I/P(current-to-pneumatic)transducer,converting an electrical 4–20 mA control signal into a proportional pneumatic output pressure typically in the range of 19–23 psi.

This module is specifically designed to control pneumatic actuators and control valves in industrial process environments where precise regulation of flow,pressure,temperature,or level is required.It ensures accurate valve positioning by translating analog control signals into pneumatic pressure outputs that drive valve actuators.

As part of the E69 family of I/P converters and positioners,the E69F-BI7-JS UNMP provides high reliability and compatibility with legacy Foxboro systems,making it ideal for use in power generation,oil&gas,chemical processing,and water treatment facilities.

Whether used as a replacement unit,for system expansion,or as a spare part,this module ensures continued operation of critical valve control systems in aging but vital automation infrastructures.
