The problem I have with running this BOB at 24v is this:

The output circuit has a pull up to 'Isolating + supply'. Without knowing the value of that resistor you can't be 100% sure its not going to fry. In the manual it shows 'Isolating Supply +5v'so I would assume they are sized for 5v and not 24v supply...
