Datexel Signal Converter Thermocouple, Output Analog - DAT2145

Zero and Span values configurable, Good accuracy, EMC compliant – CE mark - High Quality

The converter DAT 2145 is designed to provide on its output a voltage or current signal linear and proportional with the value of voltage generated from the thermocouple connected to its input.

The DAT 2145 doesn't execute the linearisation of the input signal; this feature allows to use the converter with acquisition systems with an internal linearisation software.

The user can program the input and output ranges by the proper DIP-switches available after opening the suitable door located on the side of device (see “Input range table” and “Output range table” sections).

The regulation of Zero and Span values is made by the ZERO and SPAN potentiometers located on the top of device.

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