-Each Neuron model is divided into one to three input-output (I/O) groups depending on model, each containing a group of input, output and/or communication modules. The Neuron can contain 1 (S-series), 2 (M-series) or 3 (L-series) I/O groups. ​+Each Neuron model is divided into one to three input-output (I/O) groups depending on the model, each containing a group of input, output and/or communication modules.

   * up to 64 digital inputs   * up to 64 digital inputs
Line 30: Line 28:
   * various combinations of the above-mentioned   * various combinations of the above-mentioned
  
-**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.).+{{page>​io-unipi-hidden}}
  
-**Digital outputs** can be used to control binary state devices, such as lightning switches, window shutters control, remote door control etc.+==== Additional functionality ==== 
 +{{page>​special-io-unipi-hidden}}
  
-**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. ​+===== Communication interfaces ======
  
-  * voltage measurement 0-10 V (16bit resolution) +By defaultall Neuron models feature up to **three RS485 serial lines** for connecting ​of external devices or extension modules (i.e[[en:hw:04-extensions|Extensions]]). One line can communicate ​with up to 32 devicesusing the Modbus RTU protocol
-  * voltage measurement 0-2.5 V (24bit resolution) +
-  * current measurement 0-20 mA (16bit resolution) +
-  * resistance measurement (from sensors PT100PT1000, 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.  +

-//Details about AI/AO additional functionality can be found in Neuron technical manual// +
- +
-**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 voltageTypically, relay outputs are used to switch boilers, electric motors, waterheaters or other, stronger relays. +

-===== Additional functionality ====== +
-Along with basic I/O features this product offer additional unique features, either improving its performance or making it ready for cases of emergency. +
- +
-=== Direct Switch === +
-Direct switch allows you to set appropriate device reaction based on input signal without a need of master control unit (Raspberry Pi computer build inside Neuron controller). This function is great for real-time applications. It also comes in handy in case of malfunction of the master control unit. +
- +
-=== Default configuration === +
-It is possible to store default settings inside the module memory and when the device reboots, it configures itself according to stored default settings. +
- +
-=== Master Watchdog === +
-This function periodically controls communication with the master control unit (Raspberry Pi computer). If for a period predetermined by a user there is no communication ​with the master unitit will load and set the stored default settings. Your applications will function even in emergency cases. +

-===== Communication interfaces ======+
  
-By standard, all Neuron ​models feature up to **three RS485 serial lines** for connecting ​of external devices or extension modules ​(i.e. [[en:​hw:​01-products:​01-neuron:​05-extensions|]]). One line can communicate with up to 256 devices, using the Modbus RTU protocol+Each Neuron ​also features a **single 1-Wire bus** for the passive reading ​of data from corresponding 1-Wire sensors ​(humidity sensors, temperature sensors etc.). One bus can receive data from up to 15 sensors at once (provided a suitable 1-Wire hub is used)

One bus can receive data from up to 15 sensors at once (provided a suitable 1-Wire hub is used)+As the Unipi Neuron ​product line is based on the Raspberry Pi, all Neuron controllers feature ​**up to 4 USB ports**. These ports can be used for connecting various USB convertorsexternal memory drives ​etc. We do not recommend using them to power external devices
