Iono is a general-purpose, professional input/output module (a.k.a. PLC) based on a standard Arduino microcontroller.
Iono allows you to use your Arduino programming skills, and the vast amount of software available for it, not only for prototypes, but for professional applications where extreme reliability, ruggedness and compliance with CE directives for EMC, Electrical Safety and RoHS are required.
