I'm trying to use the outputs of the A16 to control the relays of a 16-Channel 12V Relay Module that will be used for AC lights. The board is is a low-level trigger and you can see in the following pictures that I'm testing relays 16 and 15 by wiring them to GND:

   

   

Both relays seems to work fine that way, but when I try to use the A16 outputs to control it here's what happens:
Notice that the relay 16 is triggered properly, but the LED on output 16 is lit with a dim light (I've set output 14 as ON so you can compare both LEDs)

   

Now if I try to use relay 15 it doesn't work:

   

Am I doing something wrong here? The A16 output LED getting a dim light when I connect it to the relay board seems a bit odd to me, and it not being able to control all relays on the module is also odd.

I've tested all relays connecting them directly to GND and they all work, but when I do it via the A16 outputs only some of them work (e.g. 16 and 14 works but 15 and 13 do not). Could this be an issue on the relay module?

The power supply that I'm using is a brand new Mean Well HDR-60-12

Dear all, I am using the K868-A4 board with KCS V2.2.10, I have a 4-20mA sensor connected to AI1 and I am receiving the values correctly on the Monitor.

My MQTT server is configured and turned on, I receive information from my digital inputs and outputs, when they change their state, but I need to receive the data from my AD1 input, I went to System and activated the "auto send ADC values" option which would have to send me the data every 5 seconds!
This does not happen!

What should I do to make this configuration work?

Dear Support Team,

I hope this message finds you well. I have a few questions, and I would greatly appreciate your guidance and expertise:

1. How can I control four air conditioning units (Gree, Daikin, Samsung, and Toshiba) using four GPIO pins? Could you kindly assist me in setting up the ESPHome YAML file for this configuration?
   
2. Is it possible to utilize eight channels for controlling devices? If so, I would be grateful if you could provide some insights on how this can be implemented effectively.
   
3. Lastly, could you please share any updates on when the KCSFirmware will be released? I am eagerly looking forward to its availability.
   

I have a project involving three motors that I would like to connect to a wind sensor, a light sensor, and a light LED sounder sensor. For power, I will use a solar panel connected to a battery, which will provide power to a relay controller. Which relay controller should I use, and what steps should I follow?
Thank you!

Dear,

Why add external relays if the controller A32 pro has its own internal relays?

Hello
How to get ssd1306 oled display to work in a same solution with digital in and out.
Both works in its own solution, but not together each others.
Looked like they are both using same clk and dma?

Hello, is there a way in the KC868-A32 to activate the output relays via HTTP commands?

Thanks,
Alan

Hi,

Do you have a scheme to explain how to connect a NTC Thermistor sensor B3950 10K to a KC868 S series (the wire and if something else is necessary to add) ?

thanks.

Modbus protocol:

A. input register function:

temperature : 16bit unsigned integer register
humidity: 16bit unsigned integer register

address    function
0000H        temperature value
            unit: ℃
            fixed 1 decimal
            (1) >0℃: register data<10000
                          for example: register value=250, actual temperature: 250*0.1=25℃
            (2) <0℃: register data>=10000
                          for example: register value=10250, actual temperature: -1*(10250-10000)*0.1=25℃
------------------------------------
0001H        humidity value
            unit: %RH
            fixed 1 decimal
                          for example: register value=500, actual humidity: 500*0.1=50(%RH)
------------------------------------
0002H        temperature value
0003H        unit: ℃  decode: 32bit float data
------------------------------------
0004H        humidity value
0005H        unit: %RH  decode: 32bit float data


B. Hold register function:
The contents of the register are saved when power is turned off. The holding register is a readable and writable register. The value in each register is a 16-bit unsigned integer.

address    function
0000H        temperature value
            unit: ℃

------------------------------------
0002H        temperature value
0003H        unit: ℃  decode: 32bit float data
------------------------------------
0004H        humidity value
0005H        unit: %RH  decode: 32bit float data
------------------------------------
000AH        RS485 bus address(1-255), default:1 
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.
------------------------------------
000BH        Baud rate setting:
            0:4800  1:9600(default) 2:14400 3:19200 4:38400 5:56000 6:57600 7:115200
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.
------------------------------------
003DH        Parity settings
            0:None(default)  1:odd parity 2:even parity
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.

modify RS485 setting command:

register:
1001：SLAVE address 1-250
1002：Baud rate: baud_arr[8] = {4800,9600,14400,19200,38400,56000,57600,115200}
1003: Parity bit: parity_arr[3] = {UART_PARITY_NONE,UART_PARITY_EVEN,UART_PARITY_ODD}


how to remember RS485 address if you forget it.
1: every time power on will output board information by RS485 (9600,8,N,1) if you forget the board's address.
2: hold on button > 2 seconds, will reset to factory setting, default RS485 address=1
