Arduino Opta difference between analog and digital voltage range

Official Hardware Opta
1

Hello,

I once got myself an Opta for a new project.
What confuses me a bit is the following:
On the controller it says 0...10V for the inputs.
But the documentation differentiates between analogue and digital input.
Analogue up to 10 volts and digital up to 24V.
Can anyone confirm that digital IO can be processed up to 24V?
Would that mean that the AD converter just doesn't resolve further above 10V?
I would need to process a 24V signal and if I can process that directly that would be perfect.

Many thanks in advance.

Greetings, Wolfgang

Sometimes it happens that you search a while and dont find an answers and all over a sudden right after I have aske here I found it. So here the answer at the end of the post....

Finally 24V on digital I/O should be OK. Only analogue I/O is limited to 10V.

Yours,
Wolfgang

Hello, just to confirm: yes, analog up to 10V and digital up to 24V
