The TxBlock modules are a family of head mount 4 to 20 mA signal conditioners which can be used for the most common temperature applications. One single model can be configured to accept several thermocouple types and Pt100 RTD temperature sensors as well as accepting a 0 to 50 mV signal.


  • Linearised output and cold junction compensation for thermocouples
  • 3 or 4-wire Pt100 with linearisation
  • Programmable working range
  • Input digital filter for optimum 50 and 60 Hz performance
  • Programmable burnout upscale or downscale sensor failure protection
  • Sensor break detection according to NAMUR NE43 recommendations

Programming software comes with the TxBlock units, but requires a USB programming cable. The latest version of the TXConfigII software can also be downloaded directly from the Novus website.

TxBlock-USB can also be programmed by Android devices. The TxDroid Config can be downloaded from Google Play store for free.

Note: We can program the modules in small quantities for a small fee.
