UniPi Neuron S103-IQRF is a specialised variant of the basic S103 model, featuring the TR-76D smart IQRF transciever, allowing for an interoperability with various IQRF devices.
The product features an integrated Raspberry Pi 3 Model B computer
Note: The S103-IQRF variant is not compatible with the Mervis software platform.
UniPi Neuron S103-IQRF shares its I/O architecture with the basic S103 model, offering a combination of digital/analog I/O modules and a single RS485 universal bus port. In contrast to the standard S103 however, the S103-IQRF features the TR-76D smart wireless transciever, 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 transciever contains its own microcontroller and operating systém. Above the OS layer, it is possible to add 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 device‘s behavior. Additionally, an open-source development kit can be used for configuring the transciever for third-party device connectivity.
Digital inputs (DI) are used for reading 5-40V DC voltage pulses generated by various binary devices such as digital lightning switches, motion sensors, digital measuring devices (energy meters, flow meters, pressure meters) etc. Digital outputs of the S103-IQRF model also feature an in-built pulse counter.
Digital outputs (DO) are using 5-50V DC voltage pulses at 750mA max. current for switching various two-state devices such as door locks, shutter controls, automatic doors, heat pumps, lights etc. Digital outputs of Neuron controllers also feature the PWM (Power Width Modulation) function, allowing the output to transmit analog signal via binary modulated signal.
Analog input (AI) reads 0-10V DC voltage signal or 0-20mA current signal. On the S103-IQRF model, analog input can be used for precise current or voltage measurement based on current AI register settings.,
Analog output (AO) serves for regulating and controlling of various devices (three-way valves, heat exchangers, circulation pumps etc.) by 0-10V voltage or 0-20mA current signal. Analog output on the S103-IQRF model allows the user to set output voltage or current through corresponding AO register settings.
More detailed info about I/O usage and settings can be found in Neuron technical documentation (see Files tab above)
By standard, all Neuron-line controllers (except the Neuron 500 line) feature a single RS485 serial line for communication with external devices or connection of extension modules (such as Neuron xS series) using the Modbus RTU protocol. A single RS485 can communicate with up to 256 devices.
Included is also a single 10/100MBit Ethernet port for network communication and a single 1-Wire bus for connection of various 1-Wire sensors (such as digital thermometers). A single 1-Wire channel can communicate with up to 15 sensors at once.
Due to 1GB RAM and a 1.2GHz quad-core CPU, all Neuron models possess a very low response rate (ie. delay between input signal reception and output response) of approximately 0.5 ms, giving them a high level of performance.
All components are encased within a durable eloxed aluminium case providing IP20 cover. The unit's size is 4 DIN modules, DIN rail holder is included in the package.
Neuron is CE and EMC tested and is compliant with all corresponding European PLC standards. In accordance with these standards Neuron can be used in:
