- Wet contact — input («Ax» at controller) with two states: «voltage applied» or «voltage not applied». To do this, one contact of the button / reed switch / counter is connected to a voltage source (for example, to the Vout terminal), and the other to DI.
- Dry contact — input for connecting dry contact (W1, W2 at controller, WB-MR at relay modules, etc.), which check if they are shorted to ground.
One contact of the button / reed switch / counter is connected to the ground (to the GND terminal), and the other to the «dry contact» input. You can also connect outputs of the «open collector» type (connect grounds and input to output). Input status:
- closed to ground - «on»
- not closed to ground - «off»
