Description
Norcontrol HA 220782 A/A | NA-1112.1 Marine Panel
Dynamic Product Introduction
The Norcontrol NA-1112.1 HA 220782 A/A is a legacy operator panel, not a generic PLC CPU or standalone I/O module. Current marine-equipment records explicitly identify the combination as Norcontrol Automation AS NA1112.1, HA220782 A/A, with the component categorized as an operator panel.
That distinction matters when sourcing a replacement. An operator panel is part of the vessel’s human-machine interface and control architecture, so display hardware, operator controls, communication interfaces, firmware/configuration, and the connected Norcontrol system all have to agree. A replacement that simply powers up is not necessarily ready for service.
There is also useful cross-reference evidence from specialist marine inventories: the same supplier category lists NA-1112 (HA 220782/A/A) alongside NA-1112.1 (HA 220782A/A), while the individual inventory record identifies the .1 version specifically. This is why the safest procurement practice is to preserve the complete marking exactly as found on the vessel.

Key Technical Specifications
- Manufacturer: Norcontrol Automation AS
- Model: NA-1112.1
- Hardware Number: HA 220782 A/A
- Product Type: Operator panel
- Application: Marine automation/control
- System Architecture: Norcontrol legacy marine automation
- Hardware Revision: A/A
- Operator Interface: Panel-mounted operator interface; exact display/control configuration should be verified from the physical unit
- Communication Interfaces: Not safely established from the available public documentation
- Supply Voltage: Not safely established from the available public documentation
- Dimensions: Verify against the physical panel and vessel installation drawing
- Firmware: Configuration-dependent; verify from the installed panel/system
- I/O: Do not treat this as a conventional PLC I/O card
- Lifecycle: Legacy/discontinued marine automation hardware
Public documentation for HA 220782 A/A is sparse. I would not invent display resolution, supply voltage, connector pinout, processor, memory, or communication-protocol specifications simply because similar Norcontrol panels may use comparable hardware.
Global Sourcing & Live-Test SOP
1. Inbound Verification
For a HA 220782 A/A, start with physical identification:
- Confirm NA-1112.1 on the nameplate.
- Confirm HA 220782 A/A.
- Record serial number and manufacturing information.
- Photograph the front panel and rear connectors.
- Inspect display/window surfaces for cracks, delamination, or severe scratches.
- Check membrane keys, pushbuttons, selectors, and indicator lamps where fitted.
- Inspect rear connectors for corrosion and bent contacts.
Marine service history matters here. Salt contamination around connectors can create intermittent faults that are difficult to reproduce on a dry bench.
2. Configuration Verification
Before removing the original panel:
- Photograph all connector positions.
- Record cable labels.
- Record DIP-switch or jumper positions if present.
- Record firmware/version information where accessible.
- Preserve the original panel configuration.
- Compare the replacement’s PCB revision and connector population.
Do not transfer configuration settings blindly if the replacement has a different hardware revision.
3. Bench Inspection
Before energizing:
- Inspect the power-entry circuit.
- Check for obvious short circuits.
- Inspect the display backlight/power circuitry.
- Examine connectors under magnification.
- Check for corrosion or previous repair work.
- Verify the intended supply arrangement from the vessel documentation.
Use a calibrated multimeter for continuity and supply verification. Do not inject arbitrary voltage into unidentified terminals.
4. Functional Simulation
Where the appropriate Norcontrol test equipment is available:
- Power the panel using the documented supply.
- Confirm startup sequence.
- Verify display operation.
- Test all operator controls.
- Confirm communication with the associated controller.
- Check alarm indications.
- Verify command acknowledgement.
- Confirm that the panel displays the expected process/status information.
A successful power-up is only the first test. The important test is whether the panel communicates correctly with the associated NA-series control system.
5. Extended Test
For a serviceable replacement, conduct an extended operating test where practical.
Monitor:
- Display stability
- Key/button response
- Communication stability
- Unexpected resets
- Backlight behavior
- Supply-current changes
- Alarm indications
- Connector temperature
A 24-hour heat run is useful for an older marine panel when the equipment’s service criticality justifies the additional test time.
6. Final Preparation
Record:
- NA-1112.1
- HA 220782 A/A
- Serial number
- Hardware revision
- Firmware/version information
- Functional-test results
- Physical condition
- Warranty status
Package the panel with ESD protection and mechanical cushioning. Protect the display surface and connectors from impact during international transport.
Field Engineer’s Pitfall Guide
❗ Do not shorten the identification to “HA 220782.”
The available records identify the complete assembly as NA-1112.1 / HA 220782 A/A. The A/A revision is part of the useful identification, particularly when matching an old vessel installation.
❗ Do not treat the operator panel as a standalone PLC.
The panel is the operator-facing element of a larger Norcontrol architecture. Correct display and control behavior depends on the connected system, communication configuration, and vessel application.
❗ Do not assume that a working display means the panel is fully functional.
A panel can illuminate normally while communication, operator keys, alarm handling, or specific control functions remain faulty. Test the complete interface—not just the LCD/backlight.
Intent-Driven FAQ
What is Norcontrol HA 220782 A/A?
HA 220782 A/A is the hardware designation associated with the Norcontrol NA-1112.1 operator panel. Marine equipment records consistently identify this combination as a Norcontrol operator panel.
What is the Norcontrol NA-1112.1?
NA-1112.1 is a legacy Norcontrol marine automation system designation associated with the HA 220782 A/A operator panel. Specialist marine inventories list the model and hardware number together.
Is HA 220782 A/A a PLC module?
No. Available identification classifies it as an operator panel, rather than a conventional PLC CPU, analog I/O module, or digital I/O module.
Is NA-1112.1 the same as NA-1112?
They are closely related designations, and marine inventories list both NA-1112 and NA-1112.1 with HA 220782 A/A. However, when replacing equipment, retain the exact suffix from the physical nameplate rather than assuming interchangeability.
