Product Description

Siemens 771-16STF2 Current-to-Pneumatic Transducer (4–20 mA to 3–15 psig, STF2)

The Siemens 771-16STF2 is a current-to-pneumatic transducer designed to convert a DC milliampere input signal to a proportional pneumatic output signal. This configuration is specified for a 4–20 mA input and a 3–15 psig output range.

 

Signal Conversion Features

  • Input range: 4–20 mA DC
  • Output range: 3–15 psig
  • Standard output capacity: 0.16 scfm
  • Zero offset adjustment: +40% and –20% of span
  • Terminal strip electrical connection

 

Performance and Operating Characteristics

For Series 771 standard units, calibration accuracy is specified at ±1/2% of span with reproducibility of 0.2% of span and response level of 0.025% of span. The specified supply pressure is 20 psig with an operating temperature range of –40 to 180°F (–40 to 82°C).

 

Applications

  • Electronic controller to pneumatic signal conversion in process control loops
  • Pneumatic actuation and final control element interfacing
  • General-purpose installations requiring current-to-pressure conversion
