DAT 1135

General Description

The isolated converter DAT1135 is able to execute many functions such as: measure and linearisation of the temperature characteristic of RTDs
sensors, conversion of a linear resistance variation, conversion of a voltage signal even coming from a potentiometer connected on its input.

The DAT1135 is able to measure and linearise the standard thermocouples with internal cold junction compensation. The measured values are converted in a 0÷10 V signal . The device guarantees high accuracy and performance stability both in time and in temperature.

The programming of the DAT1135 is made by a Personal Computer using the software DATESOFT and the cable CVPROG, both developed and
provided by DATEXEL. By DATESOFT , that runs under the operative system “WindowsTM “, it is possible to configure the transmitter to interface it with the most used sensors .

For Resistance and RTDs sensors it is possible to program the cable compensation with 3 or 4 wires; for Thermocouples it is possible to program the Cold Junction Compensation ( CJC ) as internal or external.

It is possible to set the minimum and maximum values of input and output ranges in any point of the scale, keeping the minimum span shown in the
table below.

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 .
On the device is provided a function that allows the user to set a programmable filter up to 30 seconds to reduce eventual sudden variations of the input signal.

The 1500 Vac isolation between input and power supply/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.

It is housed in a self-extinguish plastic enclosure suitable for DIN B in-head mounting.
Moreover ( by proper mounting kit ) it is possible to mount the DAT1135 on DIN rail.
