Simple commissioning and maintenance

Smart does not have to mean complex. While the EMX4i offers more functionality than before, it has been designed to make your life easier.
 

A Starter for the future

The soft starter EMX4i includes starter, motor and system protection functions, complete with alarms to alert you to any potential issues.

By enhancing the display and connectivity functions, and making them intuitive, it is easier to access the right information when you need it, enhancing your overall efficiency.

In addition, connection to other devices and support services is easier. Connectivity has been enhanced with a range of communication cards to enable network connections and increase accessibility.
 

Pocket Technician App

Troubleshooting starting and stopping issues is now easier than ever with the Pocket Technician app. Easily retrieve useful data from any EMX4i soft starter, including starter model, status, and details of the last three trip events.
View the data on-site and diagnose issues in the field, or share it with your local support team for further assistance.
 

USB Port

The new USB port allows straightforward upload, download and storage of starter performance information, increasing your ability to manage the system effectively.

Scheduling and automation features enable you to tailor operations to meet your site requirements, minimising manual intervention and ensuring continued operation..
 

Smart Card

By upgrading your EMX4i with an industry-specific smart card, your system can be specifically built around a central point of intelligent control and communication.

In addition, different communication cards such as DeviceNet, Ethernet/IP, Modbus RTU, Modbus TCP, Profibus and Profinet can be used.
