Datexel Isolated converter RTD Input, Analog Output - DAT4531 B

RTD Input, highly Accurate, Current and Voltage Output

The isolated converter DAT 4531 B is able to measure and linearise the standard RTDs and resistances with 2 or 3 wires cable compensation. In function of programming, the measured values are converted in a current or voltage signal. The device guarantees high accuracy and performances stability both versus time and temperature.

The programming is made by the dip-switch located in the window on the side of the enclosure. By means of dip-switches it is possible to select the input type and range and the output type without recalibrate the device.

Moreover, by Personal Computer the user can program all of the device's parameters for his own necessity. For all the sensors it is possible to set the cable compensation with 2 or 3 wires.

Moreover, it is available the option of alarm for signal interruption (burn-out) that allows to set the output value as high or low out of scale.

The 1500 Vac galvanic isolation on all ways (input, output and power supply) eliminates the effects of all ground loops eventually existing and allows the use of the converter in heavy environmental conditions found in industrial applications.

The DAT 4531 B is in compliance with the Directive UL 61010-1 for US market and with the Directive CSA C22.2 No 61010-1 for the Canadian market.

It is housed in a plastic enclosure of 12.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.

The advantages for DAT4531B:

  • Configurable input for RTD and resistance

Series Information

Temperature and signal converters “SLIM SERIES”

The line of converters “SLIM series” has been designed to provide to the user the highest flexibility in the signals conversion.

The series is composed of:

  • Converters for universal input with double output and trip amplifier (DAT4530)
  • Single channel converters dedicated for typology of input (DAT4531)
  • Double channel converters (two independent inputs and outputs) dedicated for typology of input (DAT4532)
  • Signal splitters dedicated for typology of input (DAT4631)
  • Mathematical modules (DAT4632D)
  • Frequency converters (DAT4540)

It is possible to program the devices either via dip-switches to set the most common input and output ranges or via Personal Computer using the software DATESOFT by which the user can personalize the input and output ranges for his own necessities.
