The DEIF Hatlapa XL144 is a panel-mounted rudder angle indicator designed to provide accurate, real-time visual feedback of rudder position within marine steering control systems. Accepting a 10-0-10V single input signal, this instrument displays port and starboard rudder deflection and forms a critical part of the bridge navigation and steering control infrastructure onboard commercial and offshore vessels. As a key component within the Marine Control System category, the XL144 supports helmsman situational awareness and contributes directly to safe and responsive vessel manoeuvring.
Key Features
✓ Displays rudder angle position based on a 10-0-10V single analogue input signal, as specified in the original product data.
✓ Art No. 335095 references the Hatlapa product family, with additional references 600026638.10 and 472275.0004 identifying variant or configuration details — compatibility with specific systems subject to confirmation.
✓ XL144 panel format is suited for bridge console or steering gear room installation; exact dimensions and mounting requirements should be confirmed against original drawings or nameplate data.
✓ Designed for integration within Hatlapa steering control and autopilot system architectures; compatibility with specific panels or control units should be verified prior to installation.
✓ Replacement of this indicator should include signal loop verification and calibration checks to ensure accurate rudder angle representation across the full deflection range.
Marine Applications
✓ Bridge steering consoles on merchant vessels including bulk carriers, tankers, container ships, and general cargo vessels requiring continuous rudder position monitoring.
✓ Steering gear control panels in engine rooms or steering gear compartments where local rudder angle display is required as a secondary reference.
✓ Offshore support vessels and platform supply vessels operating dynamic positioning or manual steering modes where precise rudder feedback is operationally critical.
✓ Ferry and ro-ro vessel bridge systems where rapid helm response and clear rudder angle indication support high-frequency port manoeuvring operations.
✓ Retrofit and upgrade projects on vessels with existing Hatlapa steering systems requiring like-for-like indicator replacement to maintain system integrity.
Why Marine Engineers Choose
The DEIF Hatlapa XL144 Rudder Angle Indicator is a recognised OEM-referenced component within Hatlapa steering control architectures, offering a direct replacement path for vessels already operating within this system family. Its defined analogue input specification simplifies signal interface verification during installation and commissioning.
Ideal For
Merchant navy vessels, offshore support and construction vessels, ferries, ro-ro operators, and any commercial ship operator maintaining or overhauling a Hatlapa-based steering control or autopilot system.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard fault diagnosis, commissioning, and system integration for rudder angle indicator installations. Retrofit and upgrade guidance can be provided subject to review of existing system configuration. To confirm compatibility and suitability for your vessel, please share nameplate photographs, the full part number and any additional reference codes, relevant system drawings or schematics, the steering control system model and software version if applicable, and your vessel name or IMO number along with the full scope of the replacement or project requirement. All compatibility assessments are subject to confirmation based on the information provided.
