The ICV 716 is a slave board (A24/D16) allowing digital-to-analog conversion of 8 channels 16 bits.
Each channel is provided with its own converter (DAC) which can be configured in unipolar(0 10V) or in bipolar (± 10V).
The "current" option enables total generation of 0-20mA or 4-20mA current loops from a voltage of 30V supplied by the board.
At switch on the state of the output is known and equal to 0V in unipolar and in bipolar.
The presence of a double register at DACS’ level enables the notion of preloading and synchronous refreshing of the channels.
n order to ensure accuracy over long distances, the channels are equipped with differential amplifiers with remote adjustment of the 4 wire type.

Chapter A Presentation
The ICV 716 is a double Europe format VME board providing 8 analog 16-bit outputs.
The strong points of the product are:
Output configuration by channel,
status known at power-up,
remote regulation,
great precision and stability,
attractive cost.
A.1. Wiring and interconnection
If the reader wishes it, application examples of interconnections are given in the chapter Other Services "Wiring and Config" on our Web site.

Chapter B Operation
B.1. Memory space
The ICV 716 occupies a memory space of 64 bytes on the VME.
The base address must be a 256 byte module.
It is addressable in the A24 / D16 space and responds to the modified address codes 39H and 3DH.
Microprocessor transfers are performed in 16-bit words only
The green LED lights up when the first access is made to the ICV 716after an initialization.

>>>UNIPOLAR OR BIPOLAR RANGE READ
A read at any address between 00 and 1E enables the range chosen for the channels to be known.
D7 D6 D5 D4 D3 D2 D1 D0
V7 V6 V5 V4 V3 V2 V1 V0
A bit at "0" means that the channel involved is in bipolar.
A bit at "1" means that the channel involved is in unipolar.
ed. 7 [
The range of every channel is selected by the switch: SWXX1

B.3. Unipolar or bipolar outputs
Each channel of the ICV 716 board can be configured in unipolar or
bipolar (SWXX1).
B.3.1. Unipolar
SWXX1 = Unipolar
Coding is in binary
FFFF = + 9,9998V
8000 = + 5,0000V
0000 = 0V
B.3.2. Bipolar
SWXX1 = Bipolar
Coding is in binary offset
FFFF = + 9,9996V
8000 = 0V
0000 = - 10V
>>>Note:
At power-up, the board has a voltage of 0V on output in both unipolar and bipolar.
XX = channel number from 0 to 7.

B.4. Remote regulation
The ICV 716 board has a remote regulation for each channel in order to ensure the required precision at the terminals of the load.
This method called "4-wire" compensates power losses in the wires.
The diagram below illustrates the layout:

Si R1 = R2 = R3 = R4 = R
R + 2 R + Vout = Vdac ----------- x (---------- + 1)
2R + 2 R + 2
2R + 3Vout = Vdac x ------------
2R + 2

The example below illustrates the gain in precision of 4-wire regulation
Let: R load = 2K Iout = 5mA
= 1
in INA 105 R1 = R2 =R3 = R4 = 25K
a) With a remote regulation
The error is 1/50000ème
b) Without remote regulation
Vdac = Vout = (2 x Iout) + Vload
whence Vload = Vdac - 2 I
For 10V Vload = 9,990V
Let an error of 1/1000 (50 time greater).
>>>Notes:
x (Iload + I1 + I2) = VCM
This common mode voltage is inhibited by the instrumentatioin amplifier.
The term 2 comes from the fact that there is twice the same current (I1 = I2) flowing in the resistance of the wire taking the ground reference.

B.5. Current loops
In the industrial world, current loops are often used. They enable several items of equipment to be wired in series and the principle is unaffected by line power losses.
The "BC" version of the ICV 716 therefore offers the possibility of 8 "current loop" outputs.
Conditioning of the loops is complete and does not require any external power supply.
A DC/DC converter on the board supplies + 30V.
The outputs are configurable by strap in two ranges :
0 20mA ou 4 20mA
It should be noted that the unipolar voltage output 0 10V compulsory in this case is also available on the voltage output.

C.5. Outputs configuration
C.5.1. “Voltage” outputs
The SWXX1 selector with 4 changeover switches enables the channel considered to be set to unipolar or bipolar.
The position of this selector switch is read back by the system to inform
the user of the configuration chosen 10V FS or 0 10V FS.
C.5.2. “Current” outputs
When the "BC" option is chosen, the "CURRENT" outputs are available.
The current loops are supplied by a DC/DC converter which supplies 30V.
Straps on WXX3 give the choice between 4-20mA or 0-20mA.

C.6. Settings
Each channel has:
An unipolar gain setting : PXX2
A bipolar gain setting : PXX3
An Unipolar offset setting : PXX4
A bipolar offset setting : PXX1
The board is adjusted and controlled in factory with equipments of high precision.
Before adjusting the settings, the user should make sure that this is really necessary.
