TR-101 digital temperature controller is used to measure and control device temperature via four independent sensors connected in a two or three-wire circuit, with subsequent indication of the temperature on the display. The device can be used in different industrial, utility and agricultural applications.

The device has the following functions:

  • Measuring the temperature on four independent channels using standard sensors
  • Regulating the temperature using the proportionate-integral-differential (PID) principle with an output key unit (relay)
  • Two-level temperature regulation
  • Displaying the currently measured temperature value on the integrated LED digital indicator (scanning)
  • Transmitting the measured temperature values of the controlled sensors to a computer via built-in RS-485 Modbus RTU protocol
  • Discovering line breakdown or faults in connected sensors
  • Digital filtering and correcting of the temperature being measured
  • Programming via the front panel buttons or a PC (free PC software)
  • Saving the settings in case of power outage
  • Protecting the settings against unauthorized changes (password protected)
  • TR-101 can use any voltage between 24 and 260V AC, regardless of the polarity
