Hello everyone, 
I have a question concerning digital inputs. 
I have a RV, motorhome, that I would like to monitor.
So is it possible to provide 12vdc to the digital input. 
Actually, it depends on the battery voltage , but it can probably reach up to 14.7 volt dc. 

Will the digital input accept max of 14.7 volt. 

Thank you

if you using KC868-A series board , no problem, you can use it.

I do have the same question for the KC868-A4 board.

I see the board uses el357 optocoupler on the digital inputs but I found no information on the accepted input voltage.

Can you provide any information?

I have a doorbell that output 12DC when ringing and I want to connect it to one of the Digital Input. Will it work ?
What is the minimum and maximum input voltage the digital input can safely get to activate the input ?

Thank you

Digital Inputs - Supports Dry contact or voltage in.
(dc 0-12V).
Logical “0” : dc 0-4V
Logical “1” : dc 6-12V
