KC868 0-5 inputs - vincent - 08-04-2025
I have a Kincony KC868-A6 and I wonder if I could convert the 2 4-20mA inputs to 0-5v DC inputs.
I went trough the documentation (and diagram) and I can’t figure out how to do this.

I understand that I need to replace two resistance switch "4-20mA" --> "0-5v" type signal but I can't figure out what to do.
Best regards,
Vincent

compare with these two resistance. switch "4-20mA" to "0-5v" signal.

Thank you for taking the time to answer my request. In practice, could you please advice on what to do to achieve this. Should I modify the two AA2 and AA2 wiring and if so, I’m unclear on what to do and how to do this on the board? Thank you
Here is a picture of the board, could you highlight what to do please. CMS soldering is going to be a challenge for me.

KC868-A6 already have 4 channel "0-5v" adc , why you need to switch '4-20mA" to "0-5v"? KC868-A6 default adc is 0-5v
here is diagram:

ok that's good news. I thought it was only 2 inputs for 0-5V as stated on the product description page
https://www.kincony.com/images/KC868-A6/KC868-A6-2_01.jpg
it says "2 analog inputs 0-5V" but now I understand it has 4 analog inputs 0-5V.
Also, the YAML code sample for A8S referrer to 2 0-5V inputs and 2 analog inputs 4-20mA

So thank you, I don't need to change any hardware to use 4 analog inputs 0-5V.
RE: KC868 0-5 inputs - admin - 08-05-2025
yes, it's ok , work with 4 channel "0-5v".
RE: KC868 0-5 inputs - vincent - 08-05-2025
Great thank you. I'm still a bit confused with the pin reference.
Do you confirm it is 32/33/34/35?
If so why is it IO32 and I35 if the inputs are the same type?

#define ANALOG_A1 36

#define ANALOG_A3 34
#define ANALOG_A4 35
only see the left number in photo.
