The easyE4 series offers a wide range of communication options via the integrated Ethernet interface featuring the functions of a mini-PLC for machine and system control. With the integrated Modbus TCP client and server functionality, components of different levels can be integrated. The communication modules for Modbus RTU and SmartWire-DT make the easyE4 to a smart relay enabling the monitoring machines and systems. Many other functions make the easyE4 a powerful micro controller that can also be integrated into IoT system architectures. The easyE4 control relay from Eaton's Moeller series is ideally suited for implementing the control and regulation of small to medium complex applications efficiently and flexibly. It offers a wide range of custom and simple visualization options: whether on mobile devices thanks to the web server including the integrated web-editor or with the easyE Remote Touch Displays. The device can also be connected directly to Amazon Web Services (AWS).
