The TXI7800 Electro-Pneumatic Transducer transmits a pneumatic signal that is directly proportional to a DC current input signal.

The unit uses low powered microelectronics and pressure feedback control to provide a stable, accurate pneumatic output for the operation of actuated valves.

The compact size reduces weight and space requirements to simplify the piping layout to the unit. External access to the restrictor orifice simplifies unit maintenance. The unit is ideally suited for hazardous environments.

The Model TXI7800 has the following features:

• Internal Electronic Feedback maintains precise output pressure control.

• Piezoelectric Actuator Disk provides stability regardless of vibration or position.

• RFI/EMI Protection eliminates susceptibility to electromagnetic interference.

• 4-20 mA Input.

• Field Selectable Outputs in three pressure ranges match final control element requirements.

• Field Reversible Feature provides output that is directly or inversely proportional to input signal.

• Split Range Operation lets a common signal source control two or more functions.

• Damping Adjustment lets you tune the unit for optimum response.

• Compact size for use in space restricted areas.

• Input and Output Ports on the same side simplify pneumatic piping.

• Conduit fitting for easy wiring.

• Various mounting configurations allow installation flexibility for most applications.

• Explosion-Proof, NEMA 4X, IP65, Type 4 Enclosure for outdoor and indoor installations.

• Optional Tapped Exhaust Port allows venting of exhaust gas.

• A Stainless Steel Mounting Kit is available.

The Model T7900 High flow Electro-Pneumatic Transducer controls an output pressure in proportion to an analog electrical control signal. An internal feedback sensor monitors output pressure to achieve high accuracy. Model T7900 applications include machine tool automation and robotics.

The Model T7900 has the following features:

• RFI/EMI protection eliminates electromagnetic and radio interference.

• Output pressure displays in psig, BAR, or kPa.

• Reverse acting capability for input and feedback output signals

• Select Current or Voltage input signals using the keypad.

• Select Current or Voltage feedback output signal using the keypad.

• Independently adjustable PID tuning coefficients.

• Set operation parameters with the keypad.

• Backlit Liquid Crystal display screen.

• High and Low Alarm indicator lights.

The Model T7900 has the following options:

• Adjustable high and low alarm relays are available in place of Current or Voltage feedback signal.

• External Pneumatic Feedback port is available.
