Temperature Transmitter SCD 45

für Pt, Ni, KTY, TC, R, potentiometer and mV sensors, programmable via USB and DIP switches

The programmable temperature transmitter SCD 45 is used for the acquisition of industrial process signals. It converts the measured values of Pt, Ni, KTY or TC sensors as well as potentiometers, resistors and mV signals into isolated standard signals.

  • Universal measurement input
    for all common industrial sensor signals
  • Simple configuration via USB or DIP switches
    completely programmable üvia USB interface or via DIP-switch switchable
  • >Switchable service functions
    Simulation and teach-in function for simple commissioning
  • 3-port separation
    Protection against measuring errors due to grounding problems and transmission of static voltage
  • Extremely narrow design
    6.2 mm narrow side-by-side housing for simple and space-saving top-hat rail mounting
  • Optional In-Rail Bus DIN Rail Bus Connector
    allows fast and cost-effective installation
  • Safe separation according to EN 61140
    Protection of maintenance personnel and downstream equipment against excessive voltage
  • 5 years warranty
    Defects occurring within 5 years of delivery will be remedied free of charge if delivered to the factory free of charge

The programmable temperature transmitter SCD 45 is used for the acquisition of industrial process signals. It converts the measured values of Pt, Ni, KTY or TC sensors as well as potentiometers, resistors and mV signals into isolated standard signals.

The simple programming via USB interface and alternatively the calibrated range switching via DIP switch make it flexible to use.

The front switchable commissioning function generates a reference signal at the output with which the following signal path can be tested and adjusted. With the teach-in function, the measuring range limits can be taught in during operation.

With the USB programming kit the transmitter can be configured via PC and the data can be stored and documented. An additional power supply is not necessary during programming.

The power can be supplied via the terminals or via the optional In-Rail-Bus. The supply voltage and error status is indicated by an LED on the front of the device.
