3 Way Isolated Signal Converter DAT4235

General Description

The DAT4235 is a 3 way isolated signal converter that the input, output and power supply are all isolated from each other. The DAT4235 is a Din Rail mount and PC programmable. The input is Universal and selectable from thermocouples, RTD, mA, V, mV, resistance and potentiometer. The DAT4235 will linearize the input and provide a 4-20mA or voltage output signal.

The DAT4235 is accurate to 0.1% full scale and has less than 0.01%/°f thermal drift.

The DAT4235 is programmable by PC based software which has been developed by DATEXEL to be user friendly.

For resistance and RTD's sensors it is possible to program the cable compensation for 3 or 4 wires.

It is possible to set the minimum and maximum values of the input and output ranges in any point of the scale, keeping the minimum span shown in the Data Sheet. Also high burn out alarm or low burn out alarm is selectable.

The DAT4235 is isolated between the input, output and power supply to 2000V, eliminates the effects of any ground loops and allows the use of the transmitter in heavy environmental conditions found in industrial applications. The DAT4235 is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.

The DAT4235 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.

The DAT4235 is able to measure and linearize the standard thermocouples with internal cold junction compensation.
