-**Digital inputs (DI)** are designed for reading logical states (true or false), which are represented by levels of DC voltage. That makes them 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 5-30V. If the voltage is lower than 3.5V, the state is evaluated as 0 (false)+{{page>​io-unipi-hidden}}

-**Digital outputs (DO)** are used for controlling two-state devices such as lights, door locks, window blinds etc. Digital outputs on our controllers also feature the PWM (Pulse-width modulation) function, enabling a special type of analogue control. Outputs are of the NPN type (open collector) and are able to control devices with voltage up to 50V and up to 750mA load current.+===== Communication interfaces ======
  
-**Relay outputs** are used for control or switching of devices with higher current loads. ROs are thus suitable for controlling light bulbsthermoelectric valve driveswater heaters, pumps etc. Relay outputs on UniPi controllers are rated for 5A max. current at 230V AC/30V DC voltage.+Depending on the model, the Axon can feature ​**up to 4 RS485 serial lines**, **an RS232 serial line**a single **1-Wire bus** or various combinations of all mentioned interfaces
  
-**Analogue inputs** (AI) can be used for 0-10V DC voltage or 0-20mA current measuring, making them suitable for reading values from analogue sensors ​such as temperature sensors, pressure ​meters, ​tensometers etc. On some controllerstwo types of AI are available; ​the first type can be used to measure current or voltage while the second type additionally supports resistance measuring+  ​The **RS485** most often utilizes the Modbus RTU protocol and can be used for communication with a wide variety of devices ​such as energy ​meters, ​touchscreen HMI panelsPLCs from other vendors or the [[en:​hw:​04-extensions| Unipi extension]] modules. The bus can communicate with up to 32 devices with its total length being up to several hundred meters.  ​
  
-**Analogue outputs** (AO) features two modes - 0-10V DC voltage or 0-20mA direct current.
