At 6 bucks a pop, buy 2.

Seriously,  I worked with 485 at a previous job and I never blew out a non 
isolated converter.
Of course it might depend on what your doing I guess.

  Good advice is never to buy non-isolated converters.
  You will replace them regularly if you do.
  This does not seem to be isolated.
