Powerful hardware, a large selection of expansion cards and significant communication options enable the easyE4 programmable relay to be used in a wide range of applications and markets.

The integrated Ethernet interface also offers users access to the Industrial Internet of Things – (IoT). The easyE4 programmable relay replaces the existing easy500, easy700 and easy800 series.

To achieve maximum flexibility, each easyE4 base unit is equipped with four digital outputs, four analog/digital inputs with 12-bit resolution, and four high-speed digital inputs can be used, for example, as high-speed counter inputs.

All inputs can be used as interrupt inputs – a feature usually only available on more advanced controllers. An interrupt routine can be initiated for a defined event in counter, timer, or edge mode.

Another new feature of the easyE4 relay is the ability to use the DCF77 radio signal. It allows setting the time and date with high precision for each application. This information is updated automatically, for example, during the transition from winter to summer time.

With the help of expansion modules, each base unit can be expanded up to 188 I/O, which sets a new standard for compact controllers.

To facilitate the implementation of a wide range of applications, it is possible to combine easyE4 devices even in combined signal voltage levels, and the same applies to analog and digital extensions.

The expansion modules are connected from the front using the new “easyConnector” connector, which makes assembly and disassembly significantly easier.

With a total of only 14 configurations of the base unit and expansion modules, we have reduced the number of available versions compared to previous series, while at the same time expanding the scope of application. This leads to a significant reduction in procurement and storage costs.

An installed micro SD card inside the base unit opens up additional possibilities for applications. That way, program updates and maintenance features can be applied more easily.

It is also possible to pre-define a starter program on a micro SD card, which is then executed when the programmable relay is switched on. Additional memory can be used to record data, which allows documenting the state of the machine during operation.

In addition, the micro SD card allows customization of the programmable relay: company-specific images can be loaded to be displayed at start-up – for example the company logo.

Through the integrated Ethernet interface, easyE4 can be connected to any standard LAN/WLAN router, repeater or dLan system, which also enables IoT networking.

The information provided by the command relay can be displayed on web pages based on the HTML5 standard or used for visualization via the integrated “easy” web server.

Users can create their own “screens” and access the easyE4 relay from their smartphone, tablet or laptop.

Different panels can be connected directly via an Ethernet connection, for example, using the ModBus TPC protocol.

In addition, up to 80 easyE4 devices can communicate within a single network via the Ethernet interface and the integrated NET function.

The easyE4 series is designed for applications in different applications and markets, so versions for different supply voltages are available: an alternating voltage version from 85 V AC to 264 V AC, as well as a direct voltage version from 24 V DC. A special feature is the UC version (universal voltage): It can be used for voltages of 12 V DC, 24 V DC and 24 V AC.


easySoft 7 – A simple yet effective development environment


EasySoft 7 is intuitive to operate, so programming the easyE4 relay is not a challenge. Users can choose between four programming languages: ST, FBD, LD, EDP.

ST is typically used for process automation and includes additional functions for more complex applications. easySoft 7 is equipped with a large number of useful new function blocks, such as data logging, min./max., alarm module, three-step controller or e-mail alerts.

This significantly expands the range of application of the easyE4 relay. In addition, users can also create their own function blocks.

Existing programs from previous easy devices (ie the easy 500, 700 and 800 series) can simply be transferred to easySoft 7.

With the new easyE4 series of programmable relays from Eaton, you can realize various automation projects in a flexible and efficient way.
