Warnings and Precautions

The FA-DUINO is an Arduino-based industrial controller. It has features similar to those found in other Arduino products and can be programmed with the Arduino IDE. In contrast to typical Arduino products, the FA-DUINO has 24V supply power, 24V noise-filtered inputs, 24V sinking outputs, 24V 10A relays, noise-filtered analog inputs, and a more stable oscillator.

The FA-DUINO will be useful to users who are familiar with the Arduino platform when developing controllers that can be applied directly to automation sites.
