Hello there,
would it be possible to take some stance on which IN goes to which relay.
The document doesn’t say much
thank you
Please refer to:

Thank you
I still see the same problem here.
Yes, IN1 goes to Relay1.
But WHAT is the Relay1? The lastone? on which end?
If possible add a number to the picture depicting correct number 1 and 8
Relay1 is the K1 terminal, which is used to control the input signal for the first relay. Specifically:
Low-level trigger: When IN1 receives a low-level signal (typically 0V), the first relay is activated (closed), allowing current to pass through.
High-level signal: When IN1 receives a high-level signal (typically 5V), the first relay will open, stopping the current flow.
Similarly, Relay8 corresponds to the K8 terminal.
Thank you.
Where in the board is K1 terminal? Which one of the blue boxes? There is no numbering in the blue boxes.
