Datexel Signal Converter Strain Gauge Input, Analog Output - DAT5025

Isolated programmable converter for Strain Gauge / Bridge sensors, Highly Accurate

The converter DAT 5025 is designed to provide on its output a voltage or current signal linear and proportional with the output voltage coming from the output of a bridge transducers applied on its input.

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

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

The 2000 Vac isolation between input, power supply and output 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 5025 provides on the output side an auxiliary supply source to connect both active and passive loads.

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.
