easyE4 programmable relays

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). 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.

Core features

  • 4 programming languages (LD, FBD, ST, EDP) are available in easySoft
  • wide voltage range (DC, AC, UC)
  • up to 11 local expansion modules per base unit
  • various display and visualization options
  • integrated web server
  • DCF77 radio signal analysis

More flexibility with fewer components

The easyE4 and the input/output expansion modules are available with DC, AC and UC (universal) voltage, which makes them ideal for use in building or machine building applications. By means of up to 11 expansion modules, the easyE4 can be expanded to max. 188 inputs/outputs. All expansions can be mixed and combined as required. Thanks to the clever plug-in technology, the expansion modules can be quickly connected or replaced.

Ethernet interface for IIoT solutions

The easyE4 control relays are truly versatile. Up to eight easyE4 devices can be combined within one easyNET network. However, it is only when they are integrated into system architectures that the control relays demonstrate what they are truly capable of. Thanks to the easyE4's ability to function as a Modbus TCP client and server, it can be integrated into Modbus TCP networks and can also be used to set up such networks. Thanks to the use of this standard protocol, the easyE4 can be connected to a wide range of Eaton products, such as the XV100 touch display, the DA1 variable frequency drive or the S811+ soft starter. IoT system solutions can also be easily implemented via the Ethernet interface.

Create intelligent solutions with the easyE4 and SmartWire-DT

The easyE4 communication module for SmartWire-DT (SWD) perfectly combines the advantages of the powerful control relay and our intelligent wiring system. Information on the status of all connected devices, such as the current values, motor frequencies and switching states, is available via the easyE4, just as with a monitoring relay, which simplifies diagnostics and troubleshooting. In addition, parameters such as the motor frequency setpoints of variable frequency drives can be conveniently set via the control relay. Furthermore, the connection to the SWD network also ensures a compact overall footprint of the solution, both inside and outside the control cabinet. The SWD communication module offers customers who previously used the easy800 series with SmartWire-DT connection an ideal opportunity to switch to the next generation of the ‘easy’ devices.

Built-in display and mobile devices

Texts and parameters can be displayed and adjusted directly on the easyE4 using the built-in display. Thanks to the integrated web server, remote visualisation and access are also possible via mobile devices such as smartphones or tablets. In addition, the web server facilitates automatic notifications via email.

‘easy’ Remote Touch Display (RTD)

The ‘easy’ Remote Touch Display acts as the remote control for your application, mirroring the contents of the easyE4 in colour and allowing you to control it – all without having to program the RTD. The display is available in 4.3" as plug & work solution and offers an alternative to a multi-function display.

Tailor-made programming options

The user-friendly easySoft software, which is used to program the easyE4 devices, offers a quick and easy introduction to programming. Circuit diagrams can either be created and adapted on a PC, or directly on the base device. To this end, four different programming languages (EDP, LD, FBD, ST) are available, which can be combined as required. Find out more with our easySoft tutorials.

    Application programming interface (API)

    Via the standardised infrastructure of the easyE4's built-in Ethernet connection, so-called JSON objects are exchanged between the control relay and the connected web participants via the API. The easyE4 does not necessarily have to be connected to the internet in order to benefit from the wide range of possibilities. 

    Open JSON API

    easyE4 in conjunction with API and Node-RED

    The web server functionality allows you to visualise your system and control the easyE4 remotely without much effort. Using development environments like Node-Red, the easyE4 can also be synchronised with smart home devices such as Wi-Fi-enabled control relays.

    Via Node-Red, the easyE4 can also be synchronised with smart home devices. In conjunction with the JSON API, the easyE4 can then be combined with and controlled via all standard voice assistants. The possibilities are limitless.

    Using the Micro-SD card for programming

    Each base device is equipped with a micro SD card slot. Via the SD card, existing programs can simply be uploaded to the devices, which makes it much easier to commission standardised production systems, for example. In addition, an individual start-up image can also be uploaded, for example your company logo. The SD card is also used for data logging and the subsequent evaluation of operating states. In addition, the firmware can also be updated via the SD card.

    The next generation of control relays

    Find out more about why the next-generation easyE4 control relay is a real alternative to PLC systems and standard industrial relays. Whether for lighting control in buildings (for example, as a staircase timer), as a controller in automated assembly lines or for pump control in smaller systems – the easyE4 can be used as a small PLC in various applications.
