Description
An industrial digital I/O module with a Raspberry Pi RP2040 core
Iono RP D16 features 16 galvanically isolated input and output lines, controlled by the combination of two MAX22190 (IEC 61131-2 compliant industrial digital input device) and two MAX14912/MAX14913 (high-speed high-side switch/push-pull driver IC).
Protection logic built into the MCU, as well as the additional protection circuits designed specifically for the Iono RP D16, render the module extremely robust, offering long-term operational reliability, even in the most demanding conditions.
Develop your custom firmware in C/C++ or MicroPython, use your preferred IDE among the many available options for the RP2040, no need for proprietary libraries or drivers and all the resources from the Raspberry Pi community will transparently work.
Fully CE, FCC, and IC compliant, the Iono RP D16 is suitable for both residential and industrial installations.
