TR-101 digital temperature relay

TR-101 digital temperature relay 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.

TR-101 digital temperature relay 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;

 

  • transmitting the measured temperature values of the controlled sensors to a computer via the standard 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;

 

  • saving the settings in case of power outage;

 

  • protecting the settings against unauthorized changes.

 

 

TR-101 can use any voltage between 24 and 260V, regardless of the polarity
