NA-1E222.1 EMT I/O & Power Card
Nor Control AS (now part of Kongsberg Maritime)
New product
The KONGSBERG / NORCONTROL NA-1E222.1 EMT I/O & Power Card is a marine automation printed circuit board associated with Norcontrol/Kongsberg engine-telegraph and automation installations.
The unit shown in the SM MARINE SERVICE™ stock photograph contains a prominently labelled:
as well as another converter/module marked:
The board also visibly carries component references including:
U02-NCA014A
U10-NCA015A
and a D-Sub connection at the lower portion of the assembly.
Independent marine-equipment references identify the complete assembly as the Norcontrol NA-1E222.1 EMT I/O & Power Card, with PCB reference HA332402A/A/A. Some documented units additionally carry article number 6200095.
The Chinese description supplied with this equipment is:
In marine-equipment context:
康士伯 = Kongsberg
车钟板 = Engine Telegraph Board / Engine Telegraph Card
So a practical English interpretation is:
This wording is useful because many Asian marine suppliers and vessel purchasers search for legacy Norcontrol/Kongsberg equipment using component names rather than the full PCB assembly number.
However, technically the PT025 is the DC/DC converter module mounted on the PCB, rather than the verified complete board type by itself.
The complete board family is better identified using:
Original System Manufacturer / Brand: Norcontrol Automation A/S / Kongsberg
Equipment Type: EMT I/O & Power Card
Board Type: Marine Automation / Engine Telegraph I/O & Power PCB
Documented Type: NA-1E222.1
PCB Reference: HA332402A/A/A
Article / Part Number Search Reference: 6200095
Main Visible DC/DC Converter: Power Technics PT025
Additional Visible Module: PT024
Visible Reference: U02-NCA014A
Visible Reference: U10-NCA015A
Application: Engine Telegraph / Marine Automation / Control System
Associated Search Description: ETU Power Card / Engine Telegraph Board
Multiple independent current marine-spares listings use the same combination of NA-1E222.1 + HA332402A/A/A + PT025 + PT024 + U02-NCA014A + U10-NCA015A, providing strong identification support.
The NA-1E222.1 combines two important functions inside a Norcontrol/Kongsberg automation architecture:
Input / Output interfacing
and:
Internal power conversion / distribution
One current technical listing describes it as an EMT I/O & Power Card providing I/O interfacing and onboard power regulation within Kongsberg/Norcontrol marine control systems.
This combination explains why the board contains both numerous digital logic/driver components and dedicated DC/DC converter modules.
For marine engineers, the board may therefore be encountered during troubleshooting of:
Engine Telegraph Systems
ETU Assemblies
Engine Monitoring / Telegraph Automation
Norcontrol Marine Automation
DataChief-related Legacy Systems
depending on the vessel installation.
The largest and most visually distinctive component on the photographed PCB is marked:
This is important because many spare-parts enquiries are made simply as:
“Kongsberg PT025”
or:
“PT025 Engine Telegraph Board.”
But for accurate procurement, the distinction matters:
PT025 = onboard DC/DC converter module
whereas:
NA-1E222.1 = complete EMT I/O & Power Card identification found in matching marine references.
This is exactly why buyers should send a full board photograph rather than only the text PT025.
Matching NA-1E222.1 references document both:
PT024
and:
PT025
as power-conversion modules on the card.
The photograph supplied by SM MARINE SERVICE™ also visibly shows both designations.
The presence of these converter modules supports the board's role in supplying regulated onboard electrical power to the PCB's logic and interface circuitry.
SM MARINE SERVICE™ supports sourcing of this type of Kongsberg/Norcontrol legacy automation card through www.smmarineservice.com for worldwide marine customers.
The PCB contains multiple ICs, driver devices, resistors, capacitors and multi-pin connectors.
Current technical references for NA1E222.1 describe digital I/O channels used for automation signal processing and interface functions.
In an engine-telegraph/control environment, an I/O card may interface commands, indications and system-state signals between the telegraph/control hardware and the wider automation architecture.
The exact signal allocation is vessel/system-specific and should be checked against the applicable Norcontrol/Kongsberg wiring drawings.
The term ETU – Engine Telegraph Unit is highly relevant to this card because Norcontrol ETU assemblies are widely found as separate engine-telegraph units in the same legacy product ecosystem.
Current marine inventories separately identify equipment such as:
KONGSBERG NORCONTROL ETU 003 Engine Telegraph Unit
as well as the:
NA-1E222.1 EMT I/O & Power Card.
Other marine supplier catalogs also place the NA-1E222.1 card alongside Norcontrol Engine Telegraph Unit – ETU / DataChief 2000 equipment.
Therefore, describing this board commercially as an ETU / Engine Telegraph power and I/O card can be useful for sourcing, but the exact ETU assembly into which any specific NA-1E222.1 installs should always be verified from the vessel documentation.
Engine telegraph equipment forms part of the communication and propulsion-command chain between operating stations such as the bridge and engine control room.
Depending on the system design, engine telegraph electronics can handle functions such as:
Engine command transmission
Engine-order acknowledgement
Bridge/ECR command indications
Status indications
Alarm/interface signals
Communication with marine automation systems
The NA-1E222.1 should therefore be treated as a system-specific marine automation PCB, not as a generic industrial power supply.
Norcontrol/Kongsberg's older automation ecosystem includes DataChief / DC-2000 equipment.
The U10-NCA015A designation visible on this card also appears in documented Norcontrol DC-2000 DataChief Control Units, where U10-NCA015A is listed as a relevant internal reference.
This does not mean every U10-NCA015A card or NA-1E222.1 is automatically interchangeable with every DataChief unit.
It does, however, make the following terms useful related search phrases:
Norcontrol DataChief PCB
Kongsberg DC-2000 spare parts
U10-NCA015A
Norcontrol marine automation card
For global sourcing, the same board may appear under several references.
Important documented searches include:
Primary type designation.
Documented PCB/assembly reference.
Alternative printed/catalog format.
Shortened reference often used by sellers.
Article/part number documented on later/replacement examples.
Onboard Power Technics DC/DC converter.
Second power-conversion module associated with this PCB family.
Internal/component reference found on matching cards.
Internal/component reference visible on matching cards.
Using all of these identifiers significantly improves the chance of locating the correct legacy board.
One marine listing combines imagery/text referring to both NA-1E222.1 and NA-1E222.7.
These should not automatically be treated as identical or interchangeable revisions.
Before substitution, verify:
Full board type
PCB assembly reference
Revision
Connector arrangement
Component population
Vessel drawing / system compatibility
This is particularly important for old Kongsberg/Norcontrol control systems where revision changes can affect hardware configuration.
The NA-1E222.1 EMT I/O & Power Card may be relevant to marine systems involving:
The exact installation must always be verified using vessel-specific drawings.
When an ETU or associated engine-telegraph panel loses power, inspect:
Input supply
Board connector
PT024/PT025 converter section
PCB fuses/protection devices where fitted
Internal supply rails
Backplane / cabinet connection
Do not automatically replace the complete card before confirming that external power is reaching it correctly.
Possible symptoms may include:
No downstream PCB power
Unstable controller operation
Repeated restart/reset
Loss of I/O communication
Telegraph display/interface failure
Proper voltage testing should be carried out only against the correct schematic and service information.
If the power card appears energized but commands or indications are missing, inspect:
Multi-pin connectors
D-Sub interface
Backplane connections
Driver ICs
Input/output circuitry
External field wiring
A missing indication may originate outside the board.
Check:
Oxidized contacts
Loose connectors
Cracked solder joints
DC/DC converter stability
Control-cabinet supply quality
Temperature-related component failure
Legacy PCBs can develop intermittent faults that are difficult to reproduce without proper bench testing.
Do not replace individual components solely by visual similarity.
The correct component rating, board revision and circuit function must be established first.
If the board forms part of a larger Norcontrol system, check the entire system architecture, including:
Controller modules
Backplane
Power cards
I/O interfaces
Communication links
Operator units
before concluding that NA-1E222.1 itself is faulty.
The photographed PCB is a sensitive electronic assembly.
Matching marine listings specifically note that these boards are supplied using anti-static / ESD protective packaging.
When handling or replacing the board:
Use ESD protection
Avoid touching IC pins
Keep the PCB in an anti-static bag
Power down equipment before removal
Observe vessel maintenance procedures
Electrostatic damage may not always be immediately visible.
Before ordering a replacement, confirm:
Manufacturer: Norcontrol / Kongsberg
