Did you scale it? For example using an SCP AOI (Scale with parameters add on instruction)

The raw data its 0 i verify the cable and looks OK.

Check that it's wired correctly (differential/single ended). Take a look at the actual configuration words to ensure they are set as intended.

Look at the module configuration and check the limit tab. By default, all channels on a new AI card are hardware limited to practically no range whatsoever. I don't know why AB thought that this was a good idea for default values.
