-UniPi Axon is our latest PLC product line, designed to be used in monitoring, regulation, smart home, HVAC and many other applications. In its core, Axon is improved and redesigned variant of the Neuron product line. The development goal was to capitalize on Neuron'​s strengths and to further improve them. Axon thus retains a high degree of modularity and flexibility - two of our products'​ most significant advantages. ​+Unipi Axon is our latest PLC product line, designed to be used in monitoring, regulation, smart home, HVAC and many other applications.

-**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.+==== Additional functionality ====

-**Relay outputs** are used for control or switching of devices with higher current loads. ROs are thus suitable for controlling light bulbs, thermoelectric valve drives, water heaters, pumps etc. Relay outputs on UniPi controllers are rated for 5A max. current at 230V AC/30V DC voltage.+===== Communication interfaces ======
  
-**Analogue inputs** (AI) can be used for 0-10V DC voltage or 0-20mA current measuringmaking 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+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 outputs** (AO) features two modes - 0-10V DC voltage or 0-20mA direct current.
