Model T5400 Digital Pressure Transducer

Brand: Fairchild Industrial Products
The Rotork Fairchild T5400 Transducer is a digital-pneumatic device that provides a pneumatic output signal controlled by 8 bit digital data instructions from a central control room, a remote control location, or a local control station.

This device is made up of two sections, the Signal Conversion Section and the Pneumatic Section. The Signal Conversion Section (PC Board) accepts an 8 bit parallel wired digital signal. Full scale output is divided into 255 parts and the output level is based on the logic state (high or low) of the 8 bits. An enable line allows the unit to accept information from a parallel bus. 

The digital input signal is converted to an analog signal. The signal is then applied to the actuation mechanism. 

The Fairchild T5400 Fail Safe High or Low will return the output to 3 psig for Direct Acting Mode or to 15 psig for Reverse Acting Mode if the power is lost, regardless of the logic selected.
Features
  • Fail safe high or low will return the output to 3 psig for direct acting mode or to 15 psig for reverse acting mode if the power is lost, regardless of the logic selected
  • Field reversible feature provides output which is directly or inversely proportional to the input signal
  • 115 Vac, 230 Vac, and 24 Vdc power options permit use with most power sources
  • Temperature compensation provides stable operation during temperature changes
  • 5 Vdc or 15 Vdc logic assures compatibility with most digital input systems
  • Vibration resistance maintains set points, under adverse vibration conditions
  • Various mounting configurations allow installation flexibility for most applications
  • External zero adjustment provided for ease of calibration
