Opto isolated 1-Wire bus
Original Web address: Opto isolated 1
When building a 1-Wire MicroLAN, you can run into some difficulties in the way of safety
and realibilty. Reason is that the whole network has a galvanic coupling.
Where could you think of:
- Controlling mains applications; motors / valves / lights.
- ESD of touching ibuttons
- Ground loops
- Lightning
- PC / ethernet coupling
The most usefull way is to isolate the 1-Wire databus directly.
