It could be that just the usb connection was not supplying enough power

So the inputs rely on the 5V USB and not the 12/24V?

For the inputs to work you need both as you have seen you get 9V with the 24v connected which is correct.

Please use a 5V supply instead of the USB

This could have been sorted out 50 posts ago. I know you are trying but I feel like I am pulling hens teeth out

Uuuh I hope I'm not frustrating you, if I am, I'm really sorry. I really appreciate the help!
I will try it, but first I need a new BOB... When you posted it, I just fried my BOB (stupid)

But now I know why you are not keen on the USB, it didn't know that 50 posts ago...

I've updated the schematics:  

 

Perfect 

How did you burn the Bob up?

I connected the - from the 24V power supply to GND next to the input pins...

Are you sure you did not connect the+

Yes I'm pretty sure...
I can't check anymore, but I have + and - terminal blocks... and I have connected it to -

But I do have to say that here in NL you can plug-in the power socket 2 ways... (EU socket) If you know what I mean

Yes but is AC so should not matter The DC will be still +ve and _ve

How long do you have to wait for the new bob ?
