Groth,


That circuit looks pretty easy... can you give me a part number on the optical isloators.


Bill,

moot (I think... Groth verify )

By isolating the two busses optically, you are never actually connecting the two devices to the same power supply and can power the measureing devices on a separate PSU without the floating ground issue.
