|Our customers feedback resulted into construction of the new precision analog input/output module, which combines 16-bit analog inputs (functionally identical to the AI3 module) and 12-bit analog outputs (functionally identical to the AO1 module). The new AIO1 module offers one half of each module—4 input and 4 output analog channels.|
Although the combined module AD2 offers (beside 4 analog inputs) 2 analog output channels, only 8-bit resolution of these analog outputs can be insufficient in some precision-demanding applications. This is why the proven analog input part (already used in AD1 and AD2 modules) was complemented with analog output part with 12-bit D/A converter, identical to the AO1 module. Because the AIO1 module contains only 4 output channels (compared to 8 output channels of the AO1 module), it was possible to implement current output mode with range 0 to 20 mA on all 4 channels. The voltage output mode with range 0 to 10 V is also available on all 4 outputs, of course.
For detailed description od all DataLab IO modules see the hardware documentation and DataLab IO driver documentation.
Driver version 2.2 and higher must be used to work with new AIO1 module. Earlier drivers do not support these modules.
