Flexible hardware

Define ultimate flexibility in hardware design with the DEIF iE 250 Marine, tailored to meet the precise needs of your application. Offering two variants, the iE 250 Marine caters to diverse operational preferences: the front-mounted version integrates the controller and display into a single unit for those favouring a compact solution while the base-mounted option presents a modular approach, allowing for a separate and even optional display. This is ideal for applications with extensive wiring or users leaning towards a full touchscreen experience.

The modularity extends further with room for two expansion plug-in cards, ensuring that the iE 250 Marine can evolve alongside your requirements. For applications where AC measurements are not needed, the measurement board can be removed. This makes the controller not only customisable but also cost-efficient as this component represents a significant portion of the controller’s value.

Compatibility and expansion are at the core of the iE 250 Marine. For more extensive hardware expansion, the controller supports EtherCAT compatible extension racks. EtherCAT is a super-fast communication protocol that ensures an optimal experience, enhancing the performance and responsiveness of the iE 250 Marine. This comprehensive approach to hardware design and modularity underlines DEIF’s commitment to providing flexible, scalable solutions that adapt to your evolving needs.

Flexible software

The iE 250 Marine is a versatile intelligent energy controller built for customisable use in various applications. Starting with a basic core package including essential functionalities, users can add specialised software packages according to specific requirements. This modular approach allows for cost-effective customisation, including options for advanced power management, CODESYS programming enhancements, and expanded connectivity features for comprehensive system integration. Additionally, a premium package is available offering a complete set of features for users who need an all-in-one solution.

The iE 250 Marine is designed to adapt and grow with your needs, making it a scalable solution for a wide range of energy control applications.

Deliver equipment more fine-tuned to the application than ever before thanks to unparalleled customisation options of your iE 250 Marine.

The controller features CustomLogic, the intuitive drag-and-drop software tool designed for simple yet effective configuration. CustomLogic enables you to tailor specific functions and behaviours with an easy-to-use function-block editor, streamlining the process of creating customised solutions. Whether you are crafting unique configurations from scratch or importing pre-programmed function blocks, CustomLogic provides a seamless and user-friendly approach to further tailor your applications.

For projects requiring an even higher degree of customisation or complexity, the iE 250 Marine offers an integrated full-blown CODESYS* PLC. This powerful addition allows for the development of bespoke software and visualisations, ensuring complete control over both the interaction with DEIF software and what is displayed on the screen. The combination of CustomLogic and the CODESYS PLC ensures that the iE 250 Marine can be adapted to meet the exact needs of any asset, marking a new standard in control solution flexibility.


*CODESYS is an integrated development environment for programming controller applications according to the international industrial standard IEC 61131-3.
CODESYS is developed and marketed by the CODESYS Group that is headquartered in Kempten, Germany.
