FOXBORO E69F-T12-JRS Field-Mounted Current-to-Pneumatic Converter for Reliable 4–20 mA to 3–15 psi Control
The FOXBORO E69F-T12-JRS is a field-mounted I/P converter designed to translate a 4–20 mA control signal into a stable pneumatic output, typically 3–15 psi. From my experience, this series is favored on valve skids and remote panels where you want dependable pressure control without a lot of babysitting. You might notice that it’s loop-powered, which simplifies wiring and keeps commissioning straightforward in most cases. One thing I appreciate is the rugged housing that stands up to outdoor installations and the usual plant-level vibration.

Application Fields
This model is a good fit wherever an analog control signal needs to drive a pneumatic actuator or positioner:
- Oil & gas skids (separator level control, gas flow control, burner management loops)
- Refining & chemicals (valve positioners on control valves in unit operations)
- Power & utilities (steam valve actuation, soot-blowing air control)
- Water & wastewater (aeration valve control, chemical dosing with pneumatic actuators)
- OEM machinery and process skids requiring stable I/P conversion
A maintenance supervisor told us they replaced older I/P units with E69F-series devices and the loops settled much faster, especially on small pneumatic actuators where drift was an issue before.
Advantages & Value
- Reliability in harsh areas – The field housing and simple loop-powered design reduce points of failure.
- Compatibility – Works with standard 4–20 mA loops and typical valve positioners at 3–15 psi.
- Cost of ownership – Low air consumption and minimal maintenance usually mean fewer unplanned stops.
- Spares & interchange – The E69 family is widely used; replacement and interchange are typically straightforward.
- Support – Clear zero/span adjustments help technicians re-range and calibrate quickly on site.
Installation & Maintenance
- Mounting – Install on a rigid surface or 2-inch pipe; keep the unit accessible for calibration. Avoid direct heat sources and heavy vibration when possible.
- Wiring – Route the 4–20 mA pair separately from high-voltage lines. Use shielded cable and earth the shield at one end to reduce noise pickup.
- Air quality – Feed with clean, dry instrument air through a filter/regulator. A 5 μm filter and a dew point below ambient are typically sufficient.
- Start-up – Apply air, then energize the loop. Set zero and span under normal operating pressure to match your control range.
- Routine checks – Inspect fittings for leaks quarterly, verify output against a test gauge, and clean/replace the air filter as needed.
- Calibration – Annual verification is common practice; trim zero/span if the process demands tighter accuracy.
- Firmware – Not applicable; this is an analog device, which in many cases simplifies site maintenance.
Quality & Certifications
- CE compliance is typical for this series; hazardous-area approvals (such as FM/ATEX/CSA) are available on certain submodels—please verify against the E69F-T12-JRS nameplate.
- Manufacturing quality aligns with established FOXBORO process instrumentation standards.
- Warranty: 12 months from shipment.
Recommended Accessories
- Instrument air filter-regulator (with 5 μm element) to stabilize supply pressure
- Coalescing filter for oil removal where compressors are oil-lubricated
- Pressure gauge (3–30 psi) mounted near the outlet for quick visual checks
- Mounting bracket set for 2-inch pipe or wall mounting
