GENERAL DESCRIPTION
The universal isolated converter DAT 4530 is able to measure and linearise voltage, current and resistance signals, potentiometers and the standard
thermocouples and RTDs with, if required, the cold junction compensation, the wires compensation. For mV, V and mA input it is possible to set an
option for the fast sampling (option HS) or to extract the square root of the measured signal (option SQRT). In function of programming, the measured
values are converted in a current or voltage signal on the two outputs. Moreover an output contact is available as trip alarm.
By dip-switches accessible opening the window on the side of the enclosure, it is possible to select the input type and range and the output type without
recalibrate the device.
By Personal Computer the user can set the two outputs with independent settings, the parameters of the Trip Alarm and the optional parameters for his
own necessity;
The galvanic isolation between 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 device guarantees high accuracy and performances stability both
versus time and temperature.
The DAT 4530 is in compliance with the Directive UL 61010-1 for US market and with the Directive
CSA C22.2 No 61010-1 for the
Canadian market.
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 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 ).
