I don't understand how data acquisition module USB-6000 works. I have downloaded user guide of data acquisition module https://www.ni.com/pdf/manuals/373921a.pdf I think this is type of a A/D converter that takes analog input and convert it into digital output. it's just my guessing. I could be wrong perhaps

1. 1. Does module only convert analog signal into digital signal ?

2. Does module convert digital signal into analog signals?

 

It says what it is in the user manual.

It has eight analog input channels, i.e. it measures a voltage and turns it into a number on each of eight channels.

It also has four input/output digital channels, i.e. you can input or output DC voltages that are either 0V or 5V levels on four separate lines.
