Datexel DAT 4531/B Isolated converter for RTD and resistance configurable by Dip-Switch or PC


  • Configurable input for RTD and resistance
  • Configurable output in current or voltage
  • Configurable by dip-switch or PC
  • High accuracy
  • On-field reconfigurable
  • Galvanic isolation among the ways
  • UL / CE mark
  • Suitable for DIN rail mounting in compliance with EN-50022 and EN-50035


Din rail configurable by dip switch and PC converter. 1 input channel: RTD (2,3 fili) : Pt100, Pt1000, Ni100, Ni1000 and Ohm. 1 output channel (0/1...10V) and current (0/4...20mA). Galvanic insulation : power supply // input // output : 1500Vac, 50Hz, 1 min. Power supply 18...30Vdc. Reverse protection polarity 60Vdc Max.

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 their own requirements. 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 2004/108/EC on the Electromagnetic Compatibility, with the Directive UL 61010-1 for the 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.
