chip type=ESP32 you can try to replace new USB-C cable.

input 0v dc = logical "1" means: trigger
so if you want input voltage, 0V and 12V for different level.
but in this way, also if the input is in the air it gives us a 0, it only gives us a 1 when we join it with GND.
Is there any way to make the inputs 24V?
Or some other type of card?
Thanks

KC868-A16 also support DC24v power supply, the digital input also can use for 24v.
RE: Using 12v on Digital Input - jorgete - 03-08-2025
How do I have to connect the inputs? where is GND I always have to put GND if it does not short circuit, and the inputs if I leave them unconnected is the same as if I put them at 24v? a 0.
they get a 1 with GND.
So I can not use it as PNP as it says in the specifications.
Thank you.
If you can help me?

input short with GND, that means logical "true".
if you connect with 24v to INPUT, that mean logical "false".
so 0v and 24v are different logical state.

Si conecta con 24v a ENTRADA, eso significa "falso" lógico.
Entonces, 0v y 24v son estados lógicos diferentes.
Sí, son estados lógicos diferentes, pero no es PNP, solo puedes usar NPN, ¡lo cual está bien! Pero en la mayor parte de la industria en Europa se usa PNP. Gracias por la aclaración.

yes they are different logic states, but it is not PNP, you can only use NPN, which is fine!!! but for most of the industry in europe PNP is used. thanks for the clarification.

in KCS firmware, "INPUT" webpage can "invert" the logical.

I am programming it in the Arduino ide

you can also define INPUT with "invert" in arduino code. it's just a software code problem.
