FEATURES 
Isolated splitter/Converter for voltage and current DAT4631D with PC & DIP Switch programmability.
GENERAL DESCRIPTION
The isolated splitter/converter for voltage and current DAT4631D is able to measure voltage and current signals. It is programmable by PC or DIP Switches.
The DAT4631D is accurate to 0.1% full scale and has less than 0.02%/'f thermal drift.
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 table below.
The DAT4631D is isolated between the power supply and the input/output to 1500V , eliminates the effects of any ground loops and allows the use of the transmitter in heavy environmental conditions found in industrial applications.
The DAT4631D is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DAT4631D 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 Calibration of Zero and Span values is made by the ZERO and SPAN potentiometers located on the top of device.
USER INSTRUCTIONS
The converter must be powered by a direct voltage applied to the terminals Q and R.
The input 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 ).
TECHNICAL SPECIFICATIONS
INSTALLATION INSTRUCTIONS
The device is suitable for fitting to DIN rails in the vertical position.
For optimum operation and long life follow these instructions:
When the devices are installed side by side it may be necessary to separate them by at least 5 mm in the following cases:
- If panel temperature exceeds 45°C.
- Use of high power supply value ( > 27 Vdc ).
- Use of output current.
Make sure that sufficient air flow is provided for the device avoiding to place raceways or other objects which could obstruct the ventilation slits.
Moreover it is suggested to avoid that devices are mounted above appliances generating heat; their ideal place should be in the lower part of the panel.
Install the device in a place without vibrations.
Moreover it is suggested to avoid routing conductors near power signal cables (motors, induction ovens, inverters etc...) and to use shielded cable for connecting signals.

PROGRAMMING
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, 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 “Program”.
8) Set the programming data.
9) Click on “Write” to send the programming data to the device.
CONFIGURATION BY DIP-SWITCHES
1) Open the suitable door on the side of the device.
2) Set the input type by the dip-switch SW1 [1..4] (see TAB.1)
3) Set the minimum input scale value (Zero) by the dip-switch SW1 [5..8] (see TAB.3)
4) Set the maximum input value (Full scale) by the dip-switch SW2 [1..6] (see TAB.3)
5) Set the output type by the dip-switch SW2 [7..8] (see TAB.2)
NOTE:
- It is also possible to set the dip-switches using the wizard of the configuration software following the procedure described in the section ”Configuration by PC” until the step 6 and clicking on "Switch”.
NOTES:
* For all the input type selected by dip-switches, the compensation of wires is fixed at 3.
* To configure the range for the input type selected (TAB.1) refer to the section of the TAB.3 relative to it (ex: for Pt100 use the table TAB.3c ).
* If the dip-switches SW1 [1..4] are all set in the position 0 (“EPROM”), the device will follow the configuration programmed by PC ( input type and range, output type and range and options).
* If the dip-switches SW1 [5..8] are all set in the position 0 (“Default”), the device will follow the input scale programmed by PC for the input type selected by the dip-switches SW1 [1..4]
* Eventual wrong dip-switches settings will be signalled by the blinking of the led “PWR”.
