Can the UCSB work on 12 - 24vdc like the UC400Eth or strickly 24vdc?

12 Volts should also work.

Hello... Should or will? Big difference.

Then use 24V as the manual specifies, and the board was designed for.

Or let them answer the question properly

The question was already answered properly. It should, because we did not test it, but I see no problem with it.

So if you did not test it, the proper answer would be, use 24v or try 12v at your own risk.
Thanks.
I'll buy a different board that works with 12v.

The outputs can work with 12Volts, they are simply N-channel mosfets, so they can work with any voltage up to about 50Volts.
The inputs optocouplers series resistors are sized the same as the AXBB-E input resistors and they work down to 5Volts without problems. (tested)
The only thing I do not know is if the internal 5V voltage regulator which makes 5V from the 24V has any issues with 12V instead of 24V, however the worst case scenario is still that it will not output voltage and it might give audible sound.
So, the worst case scenario still will not damage anything on your board, so there is basically no risk.
If there were risk for damage then ofcourse I would tell what you said...

Shouldn't this have been the initial reply??
Instead of "should work"?
Thank you for clarifying.
