  • M-DUINO PLC Arduino Ethernet 38AR I/Os Relay/Analog/Digital PLUS

    19 Inputs
    19 Outputs

    Communications: RTC, µSD, Ethernet, USB, Full/Half Duplex RS485, RS232, I2C, Modbus

    Modular PLC
    This is the first equipment based on the Arduino technology designed for industrial and professional use. 

    Programming Software
    This PLC can be programmed using the Arduino IDE platform. See the Documentation menu below to download the software for free.

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

    (Original Arduino Mega included)

    Inputs (19)

    • (10x) 10bit – Analog (0-10Vdc) / Digital (24Vdc) Inputs, configurable by software
    • (9x) Interrupt Input (24Vdc). “Can work like Digital Input (24Vdc)”

    Outputs (19)

    • (8x) Relay outputs (220Vac-5A)
    • (11x) Analog (0-10Vdc, 8bit ) / Digital (24Vdc) Output


    • (1x) Ethernet port.
    • (1x) USB port (type B).
    • (1x) I2C port. (Interface with other Industrial Shields, sensors, I/Os modules)
    • (2x) TTL ports.
    • (1x) RS-232 port.
    • (1x) HALF/FULL Duplex RS-485 port.
    • (1x) SPI external port (Using MOSI, MISO, SS pins of Arduino)
    • TCP IP / Modbus TCP. / Modbus RTU
    • WebServer capacity
    • Industrial Protocols

    Other technical specifications

    • RTC (Real Time Clock. NOTE: I2C port used. See pinout modification)
    • µSD Socket (using SPI port, chip select D53 pin. See pinout modification).
    • 100x75x115mm
    • DIN-Rail mounting.
    • Max consum.: 1.2A
    • Flash Memory: 256kB (8kB for bootloader)
    • SRAM: 8kB
    • EEPROM: 4kB
    • Clock Speed: 16MHz

    *Rx, Tx pins are not available using RS485. For SPI you need to choose another pin for Select Function (You can choose, SDA, SCL, Rx, Tx, Pins of Arduino)

    Why PLUS

    In addition of the basic M-duino. PLUS version includes:

    • Full/Half duplex RS485 port.
    • µSD Socket
    • Possibility to use MODBUS RTU using RS485 port working as a hardware Serial.
    • RTC (Real-time clock available).
