What is a difference of Digital Input & Dry Contact? - abgran - 02-20-2023
What is a difference of Digital Input & Dry Contact at yours product. Give me the examples. Because i'm confused. Sorry i'm new in your product. Especially your product is KC868-H32BS.

usually have "Digital input" and "Analog input" for a PCB board.
"Digital input" means signal is HIGHT or LOW for CPU. maybe input=0v, maybe input=12v.
"Dry contact" means just only a OPEN/CLOSE signal, such as two wire SHORT or NOT SHORT for two state. it no power voltage, only OPEN/CLOSE.
for KinCony's board, you can use "Dry contact" signal connect to "Digital input" port, because there have 12v circuit for the INPUT circuit.

Can you give an example what device using Digital Input and what device using Dry Contact.

such as "smoke sensor", "door sensor", "motion sensor" , they all output "TRUE" or "FALSE" two state. so it use for Digital Input port. Because "Digital" on use by two state.
"Dry Contact" just one of digital input signals type.

Okay understand. Next time i'll test.
