Description

The S103 offers a basic set of digital I/Os along with a single analog I/O and single RS485 serial line. When compared to the Neuron M or Neuron L lines, the S103 has fewer I/Os, but at the same time represents the most compact Neuron model. That makes the S103 suitable for smaller automation projects focused on control of lightning or shutters, or aimed at receiving data from various smart sensors (energy meters, thermometers, motion sensors etc.)

Inputs & Outputs

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 model also feature an in-built pulse counter. 

Digital outputs (DOare 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 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 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)

Communication interfaces

By standard, all Neuron-line controllers 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. 

Other features

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 anodized aluminium case providing IP20 cover. The unit's size is 4 DIN modules, DIN rail holder is included in the package. 

Possible use

  • Lightning control
  • Boiler control
  • Temperature measurement
  • Remote home control
  • Remote shutter control
  • Notification sending
  • Energy monitoring
  • Gateway for other systems
  • Irrigation systems
  • Building management systems
  • HVAC control and regulation
  • SCADA systems

Certification

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: 

  • Residential buildings, apartments
  • Commercial areas, offices, banks
  • Entertainment areas, cinemas, bars, pubs, dance clubs
  • Outdoor places, gas stations, parking lots, sport centers
  • Areas of light industry, workshops, laboratories, service centers

The EU declaration of conformity can be found in the Files tab (see above).
