DEIF iE 250: Features and Applications
Power management of ships has seen a revolutionary change in recent years. Modern vessels operate in very sophisticated surroundings where automation, efficiency, and safety are as critical as ever. Centralization of many generators, hybrid power plants, and life-critical power transfers cannot be based on simple control anymore; it calls for intelligence.
That is what the DEIF iE 250 Intelligent Energy Controller provides. Designed for use in the marine environment, it brings power management, robust cybersecurity, and modular flexibility together in a single smart system. From ferries to offshore platforms or commercial ships of significant size, the iE 250 revolutionizes marine energy management.
An Overview of the DEIF iE 250


The DEIF iE 250 is a robust, flexible, and secure smart energy controller for next-generation ship power systems. It is essentially used to control, protect, and optimize a network of electrical equipment on board, e.g., generators, hybrid power plants, and shore power connections.
One of its strongest points is its modular hardware platform. The same controller can be configured for various vessel types without altering the underlying system. Such flexibility enables shipbuilders, designers, and operators to employ one controller in various configurations by adding, replacing, or adding on plug-in modules.
Apart from this flexibility, the iE 250 also offers robust processing power, a user-friendly interface, and advanced cybersecurity, giving mariners complete confidence in their onboard power system.
Key Features and Real-World Benefits
The DEIF iE 250 is more than just typical power control. It simplifies energy management, boosts efficiency, ensures compliance, and enhances safety during marine operations. Below are some of its most critical features:
- Modular and Customizable Architecture
The iE 250 features a highly modular architecture through which users can readily plug in input modules, output modules, or measurement modules, or even external I/O racks for advanced systems.
That makes it possible for one controller to serve from small genset applications to large hybrid applications. When operational needs evolve, modules can be replaced or upgraded with no significant reconfiguration.
Essentially, the iE 250 provides marine engineers with the ability to design and tailor energy systems to each vessel’s individual requirements.
- Intuitive Interface for Smooth Operation
Ease of use and rapid viewability are critical in marine operations. The 7-inch color touchscreen on the iE 250 delivers operators a clean and intuitive view of power performance. It is operable by touchscreen, navigation keys, or buttons, whichever is most convenient for the operator.
With DEIF’s PICUS software, engineers can tailor dashboards using a straightforward drag-and-drop interface so that only the most information-rich data appears. This personalization allows every user to configure the interface exactly as they need, making the iE 250 one of the simplest and most user-friendly marine controllers available today.
- Large Processing Capacity for Sophisticated Operations
At the heart is a quad-core CPU with the capacity to handle heavy control applications and synchronize several controllers on one busbar in real time.
For specialist applications, DEIF’s CustomLogic™ and CODESYS options enable customers to develop application-specific control logic according to specific vessel demands.
In brief, the iE 250 possesses processing capabilities to perform it all, from basic power management to advanced, multi-controller marine applications.
- Cybersecurity and Compliance
Cybersecurity is as critical today in the globalized maritime environment as physical safety is. The iE 250 is IACS UR E27 certified and assured to be fully compliant with the latest international norms of cyber resistance for maritime systems.
Such certification protects ships from cyberattacks and from non-conformity with the IACS E26 rules applicable to all newbuild vessels from July 2024.
With such assurance, business can be maintained, onboard equipment of value can be preserved, and the possibility of expensive disruption is reduced.
- Multiple Mounting and Installation Options
There’s a specific design for each vessel, and DEIF has made sure that the iE 250 will find it easy to fit into various configurations. The iE 250 provides several installation choices:
- Front-mounted: Display and controller in a single unit.
- Base-mounted with remote display: Suitable for complicated wiring schemes.
- Base-mounted local: Controller and display side by side for ease of use.
This mounting flexibility gives shipbuilders and system integrators the ability to locate the controller for maximum efficiency and ready accessibility.
- High Input and Output Capability
The iE 250 can accommodate direct plug-in I/O modules with bidirectional digital and analog channels and can also be connected to external racks like the iE 650 series for expansion.
Its intelligent terminal configuration enables the selection of channels for different applications, digital inputs, analog load sharing, or accurate measurement functions.
This makes the iE 250 a comprehensive and expandable energy management solution for straightforward as well as sophisticated marine systems.
- Smart Access, Event Logging, and Shortcuts
The controller stores up to 2,000 event logs, so operation history is readily available to analyze or troubleshoot.
In addition, programmable shortcut keys provide instant access to frequently used functions to streamline operations and minimize response times.
These thoughtful features make onboard control more effective, faster, and smoother, critical benefits in harsh marine conditions.
Applications Across Marine Engineering
The DEIF iE 250 is poised to address real-world applications encountered by marine engineers and shipmasters. Its flexibility allows it to perform multiple energy control tasks, including:
Genset Control and Protection: Provides secure, efficient operation of the generators and automatic synchronization to aid in continuous power.
Power Management Systems (PMS): Synchronizes and controls a maximum of 32 gensets for oceangoing or commercial ships.
Hybrid and Electric Power Systems: Synchronize renewable and battery-based power to conserve fuel consumption and emissions.
Shore Connection Management: Provides stable power during docking, minimizing fuel consumption and pollution.
Shaft and Emergency Generator Control: Controls sophisticated logic for standby and emergency power systems.
By incorporating all these features in one intelligent controller, the iE 250 allows ships to drive more efficiently, meet global standards, and foresee next-generation marine energy solutions.
The DEIF iE 250 is an innovation beyond intelligent marine energy control. Its future-proofing, modularity, and security render it not just a product for the time being but a long-term investment for the future.
With the marine industry embracing automation, electrification, and digitalization, the iE 250 keeps ships safe, efficient, and ready for tomorrow’s energy solutions.
