Digital Inputs with 2.2K ohm resistor
#1
So I need to know if i were to connect a DI to ground through a 2200 ohm resistor would the input trip.
I am trying to replace an old security system and all of the inputs have two states, open circuit or 2200 ohm in the line.
I would just remove the 2200 ohm resistor but most of them are not accessible.

if you want KC868-AI's board work with 12v signal by digital input port. just directly to use it. Not need replace the resistance.
