Foxboro E69F-BI2-MS Field-Mounted Current-to-Pneumatic Signal Converter

Description

Technical Specifications

• Signal Parameters
  • It supports three selectable DC current input ranges, including 4 – 20 mA, 4 – 12 mA, and 12 – 20 mA, with an input impedance of 170 ohms and supports both direct and reverse action modes.
  • The fixed output signal is 20 – 100 kPa, which is equivalent to 3 – 15 psi or 0.2 – 1.0 bar, matching the standard signal requirements of most industrial pneumatic actuators.
• Performance Metrics
  • The linearity reaches a typical value of ±0.5% of the full scale, and the repeatability achieves a typical value of ±0.25% of the full scale, ensuring consistent and accurate signal conversion.
  • The typical hysteresis is ±0.5% of the full scale, and the dead zone is 0.1% of the full scale, minimizing signal conversion delays and errors.
  • Zero drift caused by changes in supply pressure is less than 0.04% per kPa, or 0.25% per psi, maintaining stability even when the supply pressure fluctuates.
• Physical & Installation Specifications
  • It is equipped with a miniature junction box that has a 1/2 inch NPT conduit connection and adopts a front – entry design for convenient wiring and on – site maintenance.
  • The net weight of the converter is 2.3 kilograms, and the shipping weight including packaging is 4.5 kilograms, facilitating on – site transportation and installation without excessive labor input.
  • It uses a bolted cover structure that provides weatherproof protection, adapting to the harsh conditions of field – mounted applications in non – explosion – proof environments.
