I thought digital input minimum is 8v for 0
Atleast some boards have that information and AliExpress store replied 12v for input
Edit.
I was talking about dry contact inputs, why need to be 2 different digital input types ?
Edit2.
Now I see in picture where is it's for switches only "dry contact". So it works in low side ?
