AC/DC 24-240 V


Product description


Temperature-relays TR1200IP measure the temperature of up to 12 sensors within 199...+850 °C and provide the data at an ethernet interface for external evaluation. With its universal power-supply AC/DC 24-240 V it can be connected to all common supply-voltages. Actual measured values and stored min- and max-values can be displayed in a normal browser.

At the ethernet interface the following protocols are available:

  • Modbus TCP
  • IEC61850 (GOOSE) ATTENTION: for part-no. T224078 only

The TR1200IP itself does not monitor temperatures for limits. For direct monitoring of temperatures our devices with alarms and output relays are recommended.

It is used where temperatures of many sensors Pt100 shall be measured and transmitted via ethernet.

Applications are e.g. monitoring of:

  • Motors and generators (windings, bearings, coolant, ambient temperature)
  • Transformers (windings, core, ambient temperature)
  • Maschines, plants and equipment

Sensors and displays:

  • 12 inputs for sensors Pt 100 (RTD)
  • Connection in 2- or 3-wire
  • unneeded inputs can be switched off
  • Monitoring of sensors for short-circuit an interrupt
  • 3-digit-display for temperature
  • LEDs for assigning the measured value, error, state of relay and interface


  • 10 MBit/s Ethernet
  • supports IEC 61850 GOOSE
  • Protocol ZIEHL-standard RTD or Modbus TCP
  • Protocol details see - operating manuals

More features

  • easy operation and selection of temperatures at the device
  • Sensor-simulation
  • Code protection against manipulation of settings
  • Relay for Error (1 co-contact) for sensor error and operational failure
  • Universal supply-voltage AC/DC 24…240 V
  • Housing for switchgear mount, 140 mm wide, mounting height 55 mm
  • mounting on DIN-rail 35 mm or with screws M4


  • The TR1200IP can be operated with a normal web browser. There is no special software required.
