The possibility of combining different modules as required turns the XN300 into the ideal system solution for a broad range of applications. The basic product portfolio also includes gateway modules that support all Eaton I/O system components. Digital modules, which can be used both as input/output and relay modules, enable multiple application options. Analog input/output and multi-functional modules, which can perform mixed functions, are also available. Technology modules, which can, for example, be used for weighing, counting or to drive motors, further expand the scope of application.
