Thank you for your response.
Regarding the I2C address 22, the relay module works perfectly. I can read and write using channel address 1 and the data direction registers 0 and 1 without any issues.
However, when I tried the same process with the I2C address 20 for the digital input, I was unable to read or write anything. I even provided 0V (GND) to check for a response, but nothing happened.
Could you please confirm the data direction register address and channel number for the digital input module? If they differ from the relay module, I’d appreciate the correct information so I can utilize the 16 digital inputs effectively.
