KC868-A6 - how to connect an optocoupler

I think I can use a module like this https://aliexpress.com/item/1005005500489256.html. Connect the optocoupler's output to the module's input. Connect the relay contacts to ground and the digital input.
But I would like to confirm that KC868-A6 can't recognize the high state in any other way. |
