TxRail-USB is an USB configurable DIN rail mount temperature transmitter. It allows selection and configuration of input type, measurement range, output type and calibration. Its output can be set to either loop powered 4-20mA or 0-10V. Highly accurate and user-friendly, the TxRail-USB performs well from simple to sophisticated measurement applications.

The input type, zero and span and output are configured using a USB cable and the free Windows TxConfigII software.

We can program the modules in small quantities for a small fee if you wish.


  • No electrical isolation between input and output. 
  • Internal protection against polarity inversion.
  • Cold junction compensation for thermocouples.
  • Configurable measurement range
  • Sensor break detection according to NAMUR Ne43 recommendations
  • Internal cold junction compensation
  • Output Linearized according with measured temperature
  • Free Windows® configuration software
  • USB micro-B port allows direct PC connection for configuration. USB Class CDC

Programming software comes with the TxRail units, but requires either a serial or USB programming cable. The latest version of the TXConfig software can also be downloaded directly from the Novus website.
