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 Model B** as its central processing unit.

| - | **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. | + | |
| - | + | ||
| - | **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. | + | |
| - | + | ||
| - | **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 | + | |
| - | + | ||
| - | **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. | + | |
| ===== Additional functionality ====== | ===== 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. | + | Along with basic I/O features it offers additional unique features. This functionality is implemented in the internal microcontroller so it does not not rely on the main compute module or the runnin applitaction. |
| === Direct Switch === | === 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. | + | This function connects a digital input with digital output or relay output. The function is independent on the master PLC and is suitable for time-critical applications (ie. lighting control). The function can be configured to one of three available modes: |
| + | |||
| + | * Copy: output is switched by an active input | ||
| + | * Invert: output is switched by an inactive input | ||
| + | * Toggle: output is switched by any change on the input | ||
| === Default configuration === | === 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. | + | This function allows the user to store the default configuration of the module's inputs, outputs and communication lines into its internal memory. If the module is rebooted, the default configuration is loaded automatically. |
| === Master Watchdog === | === 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 unit, it will load and set the stored default settings. Your applications will function even in emergency cases. | + | The function monitors the communication between the module and the controller. If the communication is interrupted (eg. no response from the controller is detected within a defined time frame), the module automatically reboots making it to load the Default configuration. |
