GENERAL DESCRIPTION
The isolated doubler/converter DAT 4631 B is able to measure and linearise the standard RTDs and resistances with 2 or 3 wires cable 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 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.
Moreover, 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 outputs with two independent settings. For all the sensors it is possible to set the cable compensation with 2 or 3 wires.
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 (input, 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 4631 B is in compliance with the Directive 2004/108/EC on the Electromagnetic Compatibility.
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.
USER INSTRUCTIONS
The converter must be powered by a direct voltage applied to the terminals Q and R.
The analog channel measures the value from the sensor connected to the terminals the I, L and G and transmits the output measures on the terminals N
and M (OUT A) and the terminals P and O (OUT B).
The input and output connections must be made as shown in the section "Connections".
It is possible to configure the converter on field by dip-switch or Personal Computer as shown in the section " Programming ". The configuration by dip-
switches can be made also if the device is powered (note: after the configuration the device takes some seconds to provide the right output measure ).
