Isolated mathematical module for voltage and current input DAT4632D configurable by Dip-Switch or PC
GENERAL DESCRIPTION
The Isolated mathematical module for voltage and current input DAT4632D is able to measure voltage and current signals, execute a programmable mathematical function and provide a current or voltage output signal.
The DAT4632D 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 DAT4632D 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 DAT4632D is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DAT4632D 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 ).
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.
Configuration of Channel A ( see TAB.1)
2) Set the input type by the dip-switch SW1 [1..4]
3) Set the output type by the dip-switch SW1 [6..8]
4) Set the options by the dip-switch SW1 [5]
Configuration of Channel B ( see TAB.2)
1) Set the input type by the dip-switch SW2 [1..4]
2) Set the output type by the dip-switch SW2 [6..8]
3) Set the options by the dip-switch SW2 [5]
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:
* If the dip-switches SWx [1..4] are all set in the position 0 (“Default”), the device will follow the configuration programmed by PC (Input and output type and options).
* Eventual wrong dip-switches settings will be signalled by the blinking of the led “PWR”.
CALCULATION FUNCTIONS
By the configuration software, it is possible to program the logic / mathematical functions listed below. For each function it is possible to program the proportionality factors of the input and output signals to adapt the analogue signal to the physical value of the actual application requested.
The two output channels can be programmed with two independent functions.
Available mathematical functions:
A The output is proportional to the value measured on the input A.
B The output is proportional to the value measured on the input B.
A + B The output is proportional to the sum between the value measured on the input A and the value measured on input B .
A – B The output is proportional to the difference between the value measured on the input A and the value measured on input B .
A * B The output is proportional to the multiplication between the value measured on the input A and the value measured on input B .
A / B The output is proportional to the division between the value measured on the input A and the value measured on input B .
MAX (A,B) The output is proportional to the higher value between the measures on the input A and which on input B .
MIN (A,B) The output is proportional to the lower value between the measures on the input A and which on input B .
