Inputs on KC868-A16. What is correct? - Brouk - 08-30-2024
I purchased KC868-A16 from you via Aliexpress ( Order ID: 3034630932938839).
As the menu/specification table says (see the attached image), the device should have:
> 16 digital input LOG1 = +8 to 12VDC
> and 2 analog inputs 4-20mA.
But
> the device does not have digital inputs working with a positive signal, i.e. PNP. So I have to buy logic signal converters :o( .
> and even (now I found out on your site https://www.kincony.com/esp32-board-16-channel-relay-hardware.html ) that there are no analog current inputs. Is that so?
Do you have inaccurate information when selling? What is the truth?
Regards

1. you don't buy from KinCony's Official store, we don't have your order number.
2. digital input:
when digital input =0v, just short with GND, means trigger.
when digital input =8-12v, means NOT trigger.
digital input mainly use for dry contact signal.
3. KC868-A16 have 4 channel analog input ports.
actually the circuit is same, if use for VOLTAGE or CURRENT, just replace two resistance for SWITCH.
for example, if you want CHA1 use for 4-20mA, you can replace R70 resistance with 0ohm, R72 resistance with 150ohm.
every analog input channel switch as the same way. so if you want 4 channel of 4-20mA, just replace with all resistance.

Do you have a drawing showing both the input options?
Trigger = 0vdc
Not trigger = 8vdc-24vdc
I'm having a hard time understanding how to wire the inputs pnp.
RE: Inputs on KC868-A16. What is correct? - admin - 11-28-2024
you can use dry contact with digital input. if SHORT digital input port with GND = logical "1" . if input DC 12v or 24V = logical "0"

I do not get what that means can you show it in a picture please.
If I wanted to connect a switch how would I connect the wires?
24vdc to one side of the switch and input 1 to the other side?
RE: Inputs on KC868-A16. What is correct? - admin - 11-29-2024
if you switch output 24V DC. 24V signal wire connect to digital input1, another GROUND wire conenct to GND.

24vdc---------switch---------Input 1
GND ‐-‐---------------------------GND
What do you mean by switch output 24vdc?

can you draw a diagram on paper, take a photo.
