Datexel Dual Channel Thermocouple Signal Converter - DAT4532 A

Double channel, isolated converter for Tc and mV, Highly Accurate – made in Italy

The isolated converter DAT 4532 A is able to measure and linearise the standard thermocouples with internal or external cold junction 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 double channel allows the high density mounting where is necessary to reduce the encumbrances.

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.

By Personal Computer the user can program all of the device's parameters for his own necessity; the configuration by PC allows to program the two channels with two independent settings. For Thermocouple sensors it is possible to set the Cold Junction Compensation (CJC) as internal or external.

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 (inputs, outputs 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 4532 A 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.
