  • Extremely slim design
    6.2 mm slim housing for a simple and space saving DIN rail mounting
  • Optional In-Rail-Bus mounting rail connector
    allows for fast and economical installation
  • Protective Separation acc. to EN 61140
    Protects service personnel and downstream devices against impermissibly high voltage
  • 5 Years Warranty
    Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender)

The Ni Temperature Transmitter DT 45400 is used for measure industrial process signals. It converts Ni sensor signals to isolated standard signals.

Due to the easy setting of the calibrated measuring ranges via DIP switch the Transmitter is suitable for flexible use.

With the USB Programming-Kit DRAGOset the Transmitter can be configured and all data can be stored by a PC. In mode of programming no additionally auxiliary power is required.

The Commissioning Function, switchable on front panel, generates an output reference signal for testing and adjusting of the downstream signal path.

The auxiliary power can be supplied via the connection terminals or via the optional In-Rail-Bus connector. The status of power supply and sensor connection will be displayed by a LED on front.
