Well, not exactly his one but there are others with different numbers of isolation barriers/directions and these I have used.

It is common Micro controllers have at least some 5 volt tolerant inputs. I have seen one of the new Micro controllers have 5 volt externally which probably is a rather good idea even if internal logic run on lower voltage. > ...

It's a drawback but only if you have separate supply voltage for each channel otherwise they are connected anyway. _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
