Hi all,
recently I've started to build industrial machines with controllers based on ArduinoDue and Marlin4Due or Marlin2.0.
For this my company designed an Arduino-shield, which converts/adopts the 3.3V levels of the Arduino to 5V and protects them with optocouplers ... this "combo" is then placed on one of our 24V-IO-BOB's.
Here the controller, I'm actually working on - will drive a big ultrasonic cleanig system with roughly 3m x 0.5m traveling ranges along 4 vats and dryers:
Here an image of the the last US-cleaner:
