Only the 100 Ohm's, the 470 Ohm, Optokoppler, the 4V ZDiode and the 68 Ohm Resistor is needet for this Converter!
The Relays Simulatet Optocouplers.
Blubs Visualisiring Signal, no funktion.
The 1KOhm 7.4KOhm Resistornet Simulate the Canbus Hi Voltage.
120 Ohm Resistors simulate the Canbus end Resistors.
5V Powersouce simulate UVV µC
12-14,7V Powersource simulate BattPower KFZ.
This is Complitli Galanic entcoppelt over Optocouplers.
