KONGSBERG NA-1E221 / 1E-221.1 Panel Card | Marine Automation Panel Module | K-Chief & SDP Platform
Engineering Background
KONGSBERG Maritime is a globally recognized leader in integrated marine automation, dynamic positioning, and vessel management systems. The NA-1E221 (also referenced as 1E-221.1) Panel Card is a core I/O and display interface module designed for deployment within KONGSBERG’s K-Chief and SDP (Ship Dynamic Positioning) automation platforms. These systems are installed aboard offshore vessels, FPSOs, LNG carriers, and advanced naval platforms where system reliability is mission-critical.
Product Positioning
The NA-1E221 Panel Card serves as a human-machine interface (HMI) bridge within the KONGSBERG distributed control architecture. It provides panel-level signal processing, status indication, and operator input relay functions. Procurement engineers sourcing replacement or spare modules for existing KONGSBERG automation installations will find this card a direct, specification-matched solution — eliminating costly system downtime and re-engineering.

Engineering Advantages
- Direct OEM Replacement: Matches original KONGSBERG part number NA-1E221 / 1E-221.1 — no firmware re-flashing or system reconfiguration required in most installations.
- Minimized Downtime: Ready-to-install module reduces vessel off-hire risk during planned or emergency maintenance windows.
- Backward Compatibility: Designed for integration within existing K-Chief and SDP panel assemblies without hardware modification.
- Rigorous Pre-shipment Testing: Each unit undergoes functional verification prior to dispatch to ensure operational integrity.
- Traceability: Full documentation package available on request including test reports and condition certificates.
System Architecture & Signal Flow
Within the KONGSBERG K-Chief distributed automation architecture, the NA-1E221 Panel Card interfaces between the operator panel assembly and the central automation controller via the internal panel bus. It processes discrete digital inputs from panel pushbuttons and switches, drives LED status indicators, and relays alarm acknowledgment signals upstream to the main automation CPU. The card operates in a hot-standby or active configuration depending on the panel redundancy design of the specific vessel installation.
Signal flow: Operator Input → NA-1E221 Panel Card → Panel Bus → K-Chief Automation Controller → Alarm/Control Output

Technical FAQ
Q: Is the NA-1E221 compatible with both K-Chief 600 and K-Chief 700 systems?
A: In most vessel configurations, yes. However, compatibility should be confirmed against the specific panel assembly drawing and system software version. Contact our technical team for verification.
Q: Can this card be used as a direct swap without system reconfiguration?
A: For identical panel assemblies, the card is typically a plug-and-play replacement. System configuration changes may be required if the panel firmware version differs.
Q: Do you provide a warranty?
A: Yes. New units carry OEM warranty terms. Refurbished and tested-used units carry a 90-day functional warranty from Konmask.com.
Q: Can you supply multiple units for fleet-wide sparing?
A: Yes. Bulk and fleet procurement inquiries are welcome. Volume pricing available upon request.
Q: What export documentation is provided?
A: Standard export package includes commercial invoice, packing list, country of origin certificate, and test report. MSDS available if required by customs.
