IP71: Intrinsically Safe Current to Pressure Transducer



The IP71 transducer converts a current signal to a proportional pneumatic output. Using closed-loop pressure feedback circuitry, it provides precise, stable pressure outputs to final control elements.

Immunity to vibration or mounting position, high tolerance to impure air, and low air consumption make this unit ideal for demanding applications.

The compact housing, accessible ports and easy adjustments make it perfect for constrained spaces.

An integral volume booster provides high flow capacity, increasing control speed in critical applications.


  • Compact size
  • Intrinsically safe
  • Mount in any orientation
  • Easy wiring
  • Accuracy ±0.10% of span
  • RFI/EMI protected
  • I/O ports on front and back
  • Supply pressures to 100 psig

The IP71 multifunction manifold provides a common air supply line to multiple IP71 units. Manifolds are available to hold 3 or 5 units.

Each port features a patented individual shut-off valve that allows safe on-line service or modification with supply pressure on. Individual units can be installed or removed without effecting other units on the manifold. Construction is simple and flexible.

Connection ports thread easily into IP71 units. No additional hardware such as a check valve or adapter kit is required.

The manifold has an optional DIN rail mounting kit. It can also be used as a common output manifold for solenoid valves.
