Temperature Transmitter DT 45000

for Pt, Ni, KTY,TC, R, Potentiometer and mV Sensors, programmable via USB and DIP switch

The programmable Temperature Transmitter DT 45000 is used for measure industrial process signals. It converts Pt, Ni, KTY or TC sensor signals as well as poti, resistor or mV signals on input to isolated standard signals.

  • Universal Measuring Input
    for all common industrial sensor signals
  • Easy configurable via USB or DIP switches
    complete programmable via USB interface or selectable per DIP switch
  • Switchable Service Functions
    Simulation and Teach-In Function for an easy commissioning
  • 3-port isolation
    Protection against erroneous measurements due to parasitic voltages or ground loops
  • 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)

Due to the easy configu­ration via USB inter­face and the cali­brated range selection per DIP switch the Trans­mitter is suitable for flexible use.

The Commissioning Function, switchable on front panel, generates an output refe­rence signal for testing and adjusting of the down­stream signal path. With der Teach-In Function the measuring range limits can be set during operation.

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 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.
