Hi, I'm using this circuit and it works well (i splitted the 390Kohm resistor in the two circuit legs with 2x180Kohm 200V rated resistor). He senses the presence of the main AC at the Signal pin.
I have seen a similar circuit in which the 390K resistor is placed before the bridge, on the AC input side. I made it and as for my knowledge it works well too.
I would like to know if there are differences between the two circuits (in terms of reliability or other things), in case I should made a professional PCB with it.
Thanks a lot.
