What it does

The TM-2DPI accepts one of several input signal types and generates a 4-20mA or 20-4mA output.
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 Define ToolBox.
  • 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 using Define ToolBox

  • No power supply or calibrator required
  • Uses the universal USB Bridge Key (sold separately) for PC connection
