General description
DI (digital input) — input with two states. Used to connect reed switches, water and electricity meters, buttons.
Discrete inputs are of two types:
- 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). Состояние входа:
- closed to ground - «on»
- not closed to ground - «off»
«Dry» are usually called contacts that are not connected to any other circuits of the external system: relay contacts, reed switches, switches. An “open collector” output, for example, cannot be called a dry contact, since it is not galvanically isolated from an external device.
Дискретные входы в контроллере Wiren Board
В качестве дискретных входов можно использовать универсальные входы-выходы Ax (D1), которые могут работать в режиме дискретного входа в диапазоне напряжений до 40 В. Сигналы с дискретных входов отображаются в веб-интерфейсе контроллера или передаются по MQTT.

При работе канала в режиме входа переключатель Ax_OUT (D1_OUT) должен быть выключен.
