In this article, learn how a single software-configurable I/O (SWIO) IC can replace multiple aging fixed-function I/O modules.
Historically, it used to be a minor nightmare to set up a fixed-function I/O module or field junction box. With multiple combinations of hardware and wiring schemes, complexity rose exponentially as new applications came online. The newest generation of I/O modules, known as software-configurable I/Os or SWIOs, supports the end goals of older I/O modules while enabling game-changing flexibility. Not only can each channel in a SWIO be programmed as input or output, it can also be programmed as analog or digital. Additional functionality gives them the ability to read 2 or 3 wire RTDs or thermocouples. The adaptability of SWIOs is leading to rapid adoption. Click through to the article to learn more.
