FOXBORO E69F-BI2-S Product Brief Description

The FOXBORO E69F-BI2-S is a field-mounted current-to-pneumatic (I/P) transducer. It converts 4-20mA analog electric control signal from DCS or controller into proportional 3-15 psi pneumatic output signal for regulating pneumatic control valves and actuators. Built for hazardous field environments, it delivers stable and accurate signal conversion to realize remote valve position adjustment in industrial control loops.

Product Features

• Field mounted I/P transducer, converts 4-20mA electric input to 3-15psi pneumatic output
• High conversion accuracy up to ±0.5%, good linearity and repeatability for valve control
• Explosion-proof housing design, applicable for Class I Div 2 hazardous process areas
• Robust aluminum enclosure, vibration resistant for harsh outdoor/plant field installation
• Simple air supply configuration, requires clean instrument air for stable operation
• Local calibration ports for on-site zero and span adjustment without disassembly

Application Scenarios

• Petrochemical and chemical plant pneumatic control valve signal conversion
• Oil & gas processing remote actuator positioning and closed-loop regulation
• Power plant boiler auxiliary pneumatic valve control system
• Pulp & paper, pharmaceutical process control valve actuation
• Legacy Foxboro I/A DCS system field I/P transducer spare replacement
