KONGSBERG NA-1E220 Replacement for NA-Series Systems

Product Overview

KONGSBERG NA-1E220 Replacement & Upgrade Solution for NA-Series Maritime Control Systems

Migrating away from a legacy KONGSBERG NA-Series control architecture is one of the most operationally sensitive decisions a vessel owner or plant engineer can make. The KONGSBERG NA-1E220 (NA1E220.1) control board sits at the heart of numerous dynamic positioning, propulsion control, and integrated automation systems deployed across offshore vessels, drilling rigs, and marine installations worldwide. When the original board reaches end-of-life, suffers a fault, or is simply no longer available through the OEM channel, a carefully managed replacement or upgrade path is essential to maintain system integrity and minimise unplanned downtime.

Our stock of the NA-1E220 / NA1E220.1 is sourced, inspected, and dispatched from our Xiamen facility. Every unit undergoes functional verification before shipment and is covered by a 12-month replacement warranty. Whether you are executing a like-for-like swap on a vessel in port or planning a phased modernisation of an ageing KONGSBERG SDP or K-Pos system, this board provides the most direct route back to full operational status.

Seamless Upgrade Solutions

A successful NA-1E220 replacement rarely involves the control board alone. In practice, engineers working on KONGSBERG NA-series or K-Pos system upgrades encounter a cluster of interdependent components that must be evaluated in parallel. The NA-series power supply module that feeds the control cabinet should be tested before the new board is commissioned — a marginal 24 VDC rail is a common root cause of repeated board failures and will compromise the replacement if left unaddressed.

Similarly, the NA-series I/O expansion modules connected to the same backplane should be inspected for corrosion, connector wear, and firmware currency. If the vessel’s dynamic positioning system relies on a KONGSBERG SDP operator station or a K-Pos DP controller, the communication link between the operator console and the NA-1E220 board must be verified after the swap — particularly where the system uses a proprietary serial bus or a CAN-based network topology.

For installations where the control cabinet also houses a KONGSBERG thruster control unit (TCU) or an autopilot processing board, the replacement sequence should be planned to avoid simultaneous outages on multiple subsystems. Technicians frequently find that the NA-series terminal board — the passive wiring interface between field sensors and the active control board — has accumulated oxidation on its screw terminals over years of service; cleaning or replacing this terminal board at the same time as the NA-1E220 eliminates a common source of intermittent signal faults post-commissioning.

Where the upgrade scope extends to the vessel’s alarm and monitoring system, the KONGSBERG AIM (Alarm and Indication Module) connected to the NA-series network should be checked for compatibility with the replacement board’s firmware revision. In larger retrofit projects involving a full transition from an older KONGSBERG SDP 21 or SDP 22 platform to a current-generation K-Pos system, the NA-1E220 can serve as a stable interim component while the broader system architecture is modernised in stages, reducing the risk of a full-system cutover during a single drydock period.

Retrofit Guidance FAQ

Q: Do I need to rewire the cabinet when replacing the NA-1E220?
No. The NA1E220.1 uses the same backplane connector and terminal layout as the original board. Field wiring connected to the NA-series terminal board remains unchanged. A standard board swap procedure applies.

Q: Will my existing KONGSBERG application software run on the replacement board?
Yes. The NA-1E220 is a hardware replacement within the same product family. The existing application software and configuration files loaded on the KONGSBERG operator station are retained. A functional test and parameter verification are recommended after installation, but no software migration is required.

Q: Is the communication protocol compatible with the rest of the NA-series network?
Yes. The board communicates using the same proprietary KONGSBERG serial or CAN bus protocol as the original unit. No protocol converters or gateway devices are needed.

Q: How much physical space does the replacement board require?
The NA-1E220 / NA1E220.1 has an identical PCB form factor to the original. It fits the same slot in the NA-series control cabinet without any mechanical modification.

Q: What commissioning steps are required after installation?
After seating the board, power up the cabinet and verify the 24 VDC supply rail is within tolerance. Confirm communication status on the KONGSBERG operator console, run a functional I/O check against the connected field devices, and verify alarm outputs. A full DP capability plot or thruster response test is recommended before returning the vessel to operation.

Q: Can this board be used as a long-term spare?
Yes. Units are supplied in anti-static packaging suitable for long-term storage. We recommend storing spares in a dry, temperature-controlled environment consistent with KONGSBERG’s recommended storage conditions for electronic modules.

Warranty Assurance

Every KONGSBERG NA-1E220 / NA1E220.1 unit dispatched from our Xiamen facility is covered by a 12-month replacement warranty from the date of shipment. Prior to dispatch, each board undergoes a pre-shipment functional inspection to verify power-on behaviour, connector integrity, and board-level signal continuity. Units that do not pass inspection are not shipped.

In the event of a warranty claim, we provide a direct replacement unit — no repair turnaround delays. Our after-sales response target is within 24 hours of a warranty claim being raised. Replacement units are dispatched with priority freight to minimise vessel or plant downtime.

We maintain stock of the NA-1E220 and related NA-series components specifically to support emergency procurement scenarios where OEM lead times are unacceptable. Orders placed before 14:00 CST on business days are processed for same-day dispatch. We ship globally via DHL Express, FedEx International Priority, and sea freight consolidation for volume orders.

For procurement teams requiring documentation, we can provide a commercial invoice, packing list, certificate of conformity, and inspection report with each shipment. All units are shipped with ESD-safe packaging and are insured for the declared value during transit.
