XN300 I/O system

The ultra-compact, slice-based  XN300 modular I/O system with high-density plug-in connections can be combined with Eaton’s HMI-PLC products to create tailor-made system solutions. Application-oriented functions reduce the equipment cost and enable tailor-made system solutions while keeping the footprint as small as possible. Thanks to the modern design and user-friendly installation concept, the system is easy to handle and enables pre-assembly of the I/O block, the sensors and the actuators. The plug-in connections and the clear signal assignment simplify commissioning and extend the functionality of the system, enabling it to meet the specific requirements of the machine building sector.

Core features

  • Compact I/O system
  • Modern design
  • Plug-in connections
  • Tool-free push-in wiring
  • Pre-assembled blocks
  • Clear signal assignment
  • Ship approval 

Easy and flexible installation

The XN300 modules can simply be snapped into place on the DIN rail - no additional tools are required. This simplifies installation and enables the rapid replacement of individual modules. The cables simply have to be pushed into the push-in connector to make the system operational.

High modularity with a small footprint

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.

Top performance

Via the CANopen gateway, the XN300 can be integrated at fieldbus level into a powerful system that meets the requirements of even the most demanding applications. The fast "backplane" communications in the CANopen system environment enable response times of less than 1 ms, which remain constant even at the maximum number of 640 channels.


The XN300-Assist software tool supports the planning and commissioning of the XN300 modules. In addition to online features, such as the reading and setting of signal states and parameters, important auxiliary functions, including a validity check, can be performed offline.
