Industrial Arduino PLC

PLC-ARDUINO-M-DUINO

The first Arduino-based PLC controller designed for professional use by Industrial Sheilds. With the Arduino-based PLC series, you can have up to 20 inputs and outputs (I/Os).
It also includes multiple communication ports, providing greater flexibility and control.

The industrial controller family with 20 I/Os offers the possibility to expand up to 127 modules via I²C. This allows a total of up to 7,100 inputs and outputs through Master–Slave connections, in addition to sensors, actuators, and other external devices.

This industrial PLC can be easily programmed using the Arduino IDE platform or other compatible programming interfaces. Thanks to its open-source architecture, users can fully customize the PLC’s functions according to their specific needs.
