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 ).

CONFIGURATION BY PC

By software DATESOFT it is possible to:

- set the default programming of the device;

- program the options not available with the dip-switch;
(burn-out level, CJC offset, trip alarm settings, fast sampling, etc...);

- read, in real time, the input and output measures;

- follow the dip-switches configuration wizard.

To configure the device follow the next steps:

1) Power-on the device.

2) Open the protection plastic label on the front of the device.

3) Connect the interface PRODAT to the PC (COM port)
and to the device (PGRM connector).

4) Open DATESOFT.

5) Select the COM port in use.

6) Click on “Open COM”.

7) Click on the icon “Program”.

8) Set the programming data.

9) Click on the icon “Write” to send the programming data to the device.

Warning: during these operations the device must always be powered and the TX/RX cable always connected.
For information about DATESOFT refer to the software's user guide.

3) Set the output A type by the dip-switch SW1 [7..8] and SW2 [1..2] (see TAB.2)

4) Set, if available, the input option by the dip-switch SW1 [6] (see TAB.3)

5) Set the minimum input scale value (Zero) by the dip-switch SW3 [1..4] (see TAB.4)*

6) Set the maximum input value (Full scale) by the dip-switch SW2 [3..8] (see TAB.4)*

configuration software following the procedure described in the section
”Configuration by PC” until the step 6 and clicking on icon “Switch”.

THRESHOLD OPERATION

For the high alarm the relay goes on when the input signal is higher than
the trip level and after the delay time. The relay goes off only when the
input signal is lower than the trip level minus the hysteresis value or when
reaches the minimum value of the input scale and after the delay time.

For the low alarm the relay goes on when the input signal is lower than the
trip level and after the delay time. The relay goes off only when the input
signal is higher than the trip level plus the hysteresis value or when
reaches the maximum value of the input scale and after the delay time.
