GENERAL DESCRIPTION
The isolated double channel converter DAT 4532 C is able to measure and linearise the standard PTC and NTC sensors and potentiometers. 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 double channel allows the high density mounting where is necessary to reduce the encumbrances.
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 channels with two independent settings.
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 (inputs, 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 4532 C 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 channel A measures the value from the sensor connected to the terminals I, L and G and transmits the output measure on the terminals N and M.
The channel B measures the value from the sensor connected to the terminals E, F and H and transmits the output measure on the terminals P and O.
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 ).
