Topic: Arduino
* Model:


This is the first PLC equipment based on the Arduino Technology designed for a professional use.

Taking Arduino Mega2560 as its core control chip, the M-Duino PLC has 21 I/Os including 6 analog and digital inputs, 5 digital isolated inputs, 2 interrupt isolated inputs, 3 analog outputs, 5 digital isolated outputs, and 3 PWM isolated outputs. Meanwhile, it contains several communicate ports like, UART, I2C, SPI, RS232, RS485, Ethernet, which provide more flexibility to control your device. Besides, the controller offers the possibility to expand up to 127 modules via I2C.

This PLC can be programmed using the Arduino IDE and supports remote programming through the Ethernet port. Also you can continuously monitor the status for all the variables, inputs, outputs, etc. It is compatible with the Ardbox, M-duino and the Touchberry Pi with an instantaneous connection.
