All Neuron models are using the **Raspberry Pi 3 Model B** as its central processing unit. Each I/O group is connected to the CPU and to a central communication channel for all group processors. There is no communication between I/O groups. **Each processor can also function independently on the CPU, allowing users to retain basic control of I/O modules in the event of CPU malfunction or software issue**. | All Neuron models are using the **Raspberry Pi 3 Model B** as its central processing unit.

- | **Digital inputs** use binary logic; that makes them two-state inputs utilizing DC voltage pulses. Axon digital inputs are designed for 5-40V DC voltage range, receiving voltage pulses from corresponding external devices. Typical examples of such devices are digital lightning switches, magnetic contacts in windows or doors, motion sensors etc. It is also possible to connect pulse meters (energy meters, water flow meters etc.). | + | **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) |

- | **Digital outputs** can be used to control binary state devices, such as lightning switches, window shutters control, remote door control etc. | + | |
- | + | ||
- | **Analog inputs** are used to receive either 0-10V voltage or 0-20mA current signals. Alternatively, they can be used for reading data from corresponding sensors, such as resistance thermometers. The user can adjust the input mode via corresponding control software. | + | |
- | * voltage measurement 0-10 V (16bit resolution) | + | **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. |

- | * current measurement 0-20 mA (16bit resolution) | + | |
- | * resistance measurement (from sensors PT100, PT1000, NTC) in three wire (three conductors, 0-100 Ω, 24bit resolution) or two wire (two conductors, 0-1960 Ω, 24bit resolution) wiring method.. | + | |
- | **Analog outputs** operate in voltage range 0-10 V (12bit resolution). Analog inputs allow more precise measurement (they have higher bit resolution). Group 1 outputs allow the user to set required output voltage current, while Group 2 outputs can be used for resistance measurement. | + | **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. |
- | //Details about AI/AO additional functionality can be found in Neuron technical manual// | + | **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 controllers, two types of AI are available; the first type can be used to measure current or voltage while the second type additionally supports resistance measuring |
- | **Relay outputs** are dimensioned for a maximum voltage of 250V AC/30V DC with maximum current of 5A. The main purpose of these relays is switching of two-state external devices through alternating or direct voltage. Typically, relay outputs are used to switch boilers, electric motors, waterheaters or other, stronger relays. | + | **Analogue outputs** (AO) features two modes - 0-10V DC voltage or 0-20mA direct current. AI serves for control of devices with analogue input, such as three-way valves, lighting dimmers etc. |
