Inputs & outputs description

Digital inputs (DI) are designed to read binary logic states represented by direct voltage levels. That makes them suitable for reading data from various binary sensors and devices such as switches (on/off), motion sensors (movement detected/not detected), liquid level sensors (full tank/empty tank) etc. 

Digital outputs (DI) are intended for switching various binary devices (lighting, smart door locks, drives of shutters and blinds etc.) through direct voltage. DO's also feature a Pulse-Width Modulation (PWM) function allowing to use the output for analogue control. All digital inputs also feature counter functionality by default. 

Analog input (AI) is designed to measure voltage, current or resistance to read values from various analogue sensors such as thermometers, pressure meters, tensometers etc.

Analog output (AO) serves for control of multi-state external devices through direct voltage or current and is suitable for control and regulation of devices such as three-way valves, heat exchangers, electric motors etc. 

Computing module

The controller is powered by Raspberry Pi 3 Model B featuring quad-core 1.2GHz CPU and 1GB RAM, giving it more than enough performance for various performance-demanding applications. MicroSD memory cards are used as memory storage.

Special features

The TR-76D transceiver, operating on 868 or 916 MHz bands (can be configured through a corresponding software) and utilizing the IQRF Technology wireless standard. This standard uses a highly reliable wireless mesh communication broadcasted on sub-gigahertz bands. Such technology has two main advantages – long signal range and low power consumption. Thanks to the long-range, the user does not have to use repeaters or base stations to extend the signal range, and due to using a patented Directed Flooding mesh networking protocol, the communication retains its reliability even in harsh RF environments.

The transceiver contains its microcontroller and operating systém. Above the OS layer, it is possible to add the DPA transport layer containing pre-made hardware profiles. These can be used to quick device setup for needed functionality without any further programming. If needed, there is also a possibility to add a third layer for custom adjustments of the device‘s behaviour. Additionally, an open-source development kit can be used for configuring the transceiver for third-party device connectivity.

 

Communication interfaces

Neuron controllers are by default provided with RS485 serial lines. This type of interface usually uses the Modbus RTU protocol and can be used to communicate with various devices such as Extension xS extension modules, energy meters, touchscreen HMI displays, controllers from other vendors, various sensors etc. A single bus can support dozens of devices while the bus' length can reach up to several hundred meters.

A single 1-Wire bus is also included. This interface uses 2-3 conductors for collecting data from various 1-Wire sensors such as thermometers, humidity meters, light intensity sensors etc.). A single 1-Wire bus supports up to 15 devices, the overall length of the bus can reach up to 100 meters. 

All Neuron models also feature a single Ethernet port for network communication

Software options

Thanks to the software openness of Unipi controllers customers can choose from a broad range of software solutions and are not limited to a single platform Among supported solutions are both commercial and open-source systems. Visit the Other software overview for the list of other supported solutions.

The main supported solution is the Mervis control system - a platform developed under the IEC 61131-3 standard for PLC programming, that includes SCADA interface for remote management and monitoring, a comprehensible development environment, a human-machine interface (HMI) editor and an online/on-premise database for storing historical data and retrospective analysis of the controlled technology's operation. 

Aside from commercial platforms you can also choose any from the list of supported open-source solutions, or use the EVOK API (Websocket, REST,...) Modbus TCP, SysFS or other tools for implementing your logic in any programming language. Visit this link for the list of supported software solutions.
