Digital inputs

The digital inputs (DI) are for reading logical states (true or false), which are represented by levels of DC voltage. The DIs are therefor suitable for reading two-state sensors such as switches (on/off), movement sensors (movement, no movement), water level sensors (water present, no water) etc. The software detects logical 1 (true) if the input voltage between given DIx.y and DIGND is between 5-35V. If the voltage is lower than 3.5V, the state is evaluated as 0 (false)

The DIs on the Unipi units are galvanically isolated, which means it is safer to use them in an environment affected by electromagnetic interference.
