Project Description


Iono is a work-suit for Arduino, it turns it into a PLC that combines the ease of use of the Arduino platform and the vast amount of software available for it with robust input and output electronic interfaces.

  • Power Supply
  • Relays
  • Analog I/Os
  • Digital Inputs
  • RS-485
  • DIN-Rail Case
  • CE/RoHS Certified






Iono can be employed both in industrial and residential environments, for professional applications where extreme reliability, ruggedness, and compliance with technical and safety directives are required.

It is compliant with the 2014/35/UE (Low Voltage) and 2014/30/UE (EMC) CE directives, and the harmonized standards for electromagnetic compatibility (EN61000-6-2:2005), electrical safety (EN60664-1:2007), emission (EN61000-6-3:2007) as well as the RoHS directive for hazardous substances (2011/65/UE).




Iono can be used in several ways:

As an armored Arduino

You can do anything you are able to do with an Arduino, in the same exact way, programming it with the standard Arduino IDE. You just have a more robust hardware that will help you transition from your prototype to your final professional project.

As an Ethernet I/O module

Out of the box, Iono Ethernet includes a Web application and it is ready to be used as a simple Ethernet I/O module that you can control and configure through a nice Web interface and/or with a simple HTTP API.


As a Modbus module

Are you more at ease with Modbus devices? No problem, just upload the Modbus TCP or Modbus RTU sketches available from the libraries examples (Iono Uno ships with the Modbus RTU Slave sketch pre-installed) and your Iono turns into a standard Modbus module, configurable with a simple serial interface.


Of course, you can always modify the provided Web and Modbus sketches and add your custom logic!
