With the easyE4 control relays Eaton's Moeller series, control tasks can be implemented quickly and efficiently, whether it be in industrial, specialized manufacturing or building applications. Up to 11 I/O expansions as well as a wide range of voltages are available. The new easyE4 devices are not only easy to handle, but also offer simple and flexible programming. The easySoft software is intuitive to use and comes with four different programming languages. The addition of other functions, such as the integrated web server and Ethernet interface, turns the easyE4 into a powerful control relay that can also be integrated into IIoT system architectures.
