DI is used to connect reed switches, water and electricity meters, buttons. To do this, one contact of the button/reed switch/meter is connected to a voltage source (for example, to the V out terminal), and the other - to DI. The DI state(zero or one) indicates whether the circuit is closed or open. | DI is used to connect reed switches, water and electricity meters, buttons.
