TM-2DLI 2-Wire Universal Transmitter




This versatile 2-wire transmitter accepts a range of standard input types, and outputs a 4-20mA loop. USB programming is hassle free, and takes less than a minute using our purpose-built Define Toolbox software.

  • 2-wire universal transmitter (DIN-mount, isolated)
  • Current, voltage, thermocouple, RTD and potentiometer input
  • Loop powered, 4-20mA output
  • LED indicator for error notification
  • Potentiometer for fine offset adjustment of current output

Easy USB programming

 

  • No power supply or calibrator required
  • Uses the USB Bridge Key for PC connection
