Such devices form a signal by closing two wires that are suitable for them. Connect one wire to the GND terminal of the module. Connect the second wire to the Dx terminal. A current of less than 2 mA flows through the button. Some counters have a pulse output on the optocoupler, then the two wires have a polarity - "plus" and "minus". In this case, minus is connected to GND, plus to Dx. | Such devices form a signal by closing two wires that are suitable for them. Connect one wire to the GND terminal of the module.
