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
