Galvanic Isolation

Does the RA head unit have the same Galvanic Isolation as the pH expansion module?

no

If I bought a Ph expansion would it be hard to make the output from it replace the one from the head unit on the display and clients?

In the display it is pretty simple.
The android app and Portal already support it automatically too.
