Industrial Arduino PLC

Industrial Automation based on Open Source Hardware

Modular PLC Controller

This is the first equipment based on the Arduino technology designed for professional use.  With the PLC Arduino range, you can have up to 20I/Os. It also contains several communication ports, which provide more flexibility and control. The 20IOs industrial controller family offers the possibility to expand up to 127 modules through I2C, which means that you can have until 7100 Inputs / Outputs in Master-Slave connections, additionally to sensors, etc…

Programming Software

This industrial PLC can be programmed using the Arduino IDE platform and other programming languages or interfaces, since it is open source.

Instantaneous connection and coding

The controller Arduino PLC 20IOs is programmed through the USB ports. This offers and immediate access to program, maintain and control. Also, you can continuously monitor the status for all the variables, inputs, outputs, etc. It is compatible with the Ardbox PLC Range and the Touchberry Pi with the instantaneous connection.

Easy Setup and Installation

It complies with regulations for industrial automation.


Connect an external memory card or copy your important data using USB.
