Learn the differences between two of our most popular and powerful controllers.
Both the X-400 and the X-600M are expandable with our modular I/O products. However, they have some differences between them, such as security, dashboards, number of supported I/O and more.
X-600M
The X-600M is our master controller that offers multiple customizable dashboards, making multiple device management easy. With support for up to 1,024 I/O, the X-600M acts as a simple SCADA that is perfect for large sized projects that need to be managed in one place.
