Modular PLC
This is the first equipment based on the Arduino technology designed for a professional use. This PLC has 58I/O1. It also contains several communication systems1 which provide more flexibility and control. The M-DUINO 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 PLC can be programmed using the Arduino IDE platform. See the Documentation menu below to download the software for free.

Instant connection and coding.
The PLC M-DUINO is programmed through the USB ports. This offers and immediate access to program, mantain and control. Also you can continuously monitor the status for all the variables, inputs, outputs, etc. It is compatible with the Ardbox and the Touchberry Pi with instantaneous connection.

Solar panels are popular because they are able to give us energy from light. When the light hits the panel solar conductor, the energy is translated into moving and electrons, creating current. In this newsletter we´ll make a simple monitoring





3 reviews for M-DUINO PLC Arduino 58 I/Os Analog/Digital

  1. 5 out of 5


    – Control of cold and frozen storage (similar to chaotic warehousing).
    – Inbound&Outbound movements.
    – Distribution integrated with ERP orders and automated barcode reading.

  2. 4 out of 5


    The PLC, installed in a solar panel farm, sends and receive information to/from the control center: real-time energy generation, breakdown alarms, etc.

    Suggestion: the equipment should be IP65! For outdoor installations, it is important!

    Hard config cause we take care of dozens of sensors in a wood manufacturing line. Working as expected. 3rd duino and more to come.
