Description
Rolls-Royce H1127-0101 | Marine Controller Module
Dynamic Product Introduction
The Rolls-Royce H1127-0101 is the kind of controller that becomes difficult to source when a vessel has been operating for years and the original automation architecture is no longer supported as a normal catalog item. It is identified in multiple current spare-parts records as a marine controller using the H6045/433 MHz platform, with RR Part No. 000068308 and PIC Code Rev. 2.2.
This is not a generic PLC CPU that should be selected by voltage and connector count alone. The installed application, controller revision, memory-card arrangement, firmware/PIC code, and vessel-specific configuration can determine whether a physically identical H1127-0101 is actually usable. One current listing specifically describes a unit without its memory card, which is a significant sourcing detail for marine control equipment.
The H1127-0101 is therefore most useful as an exact-match maintenance spare rather than as a general-purpose automation controller. When replacing one in an operating vessel, preserve the original configuration wherever possible instead of assuming that a bare replacement module contains the vessel application.

- Reported unit weight: Approximately 2.010 kg
- Memory configuration: Configuration-dependent; some available units are specifically listed without a memory card
- Communication/interface hardware: Must be verified from the actual controller and vessel configuration; do not assume every H1127-0101 listing has identical populated interfaces

- Replacement status: Treat as an exact-revision spare unless the vessel’s engineering documentation identifies an approved successor
The H6045/433 MHz and 000068308 identifiers are repeated across several independent industrial/marine inventory records, providing a useful cross-check when screening surplus inventory.
Global Sourcing & Live-Test SOP
For a marine controller, visual inspection is only the first gate. A clean enclosure does not prove that the stored application, memory hardware, or communication interfaces match the vessel.
1. Inbound verification
- Photograph the complete nameplate before removing packaging.
- Confirm , 000068308, H6045/433 MHz, and PIC Rev. 2.2 where applicable.
- Record serial number and PCB/controller revision.
- Compare connector population against the removed controller.
- Check for corrosion, salt residue, oxidation, cracked connectors, bent pins, and evidence of previous rework.
- If customs or OEM paperwork is available, trace the serial number and shipment documentation.
- Be cautious with units described only as “Rolls-Royce compatible.” Exact identification matters here.
2. Memory and configuration verification
- Confirm whether a memory card is included.
- Do not assume a controller adved as contains the vessel’s application.
- Preserve the original controller and memory hardware until the replacement has completed acceptance testing.
- Record existing firmware/PIC information before commissioning.
3. Bench simulation
- Use the documented vessel-system power and communication requirements rather than applying arbitrary bench voltage.
- Verify startup behavior and status indications.
- Check communication ports against the original unit.
- Where possible, perform a controlled communication handshake with the appropriate engineering test environment.
- Monitor supply current and temperature during startup.
4. Diagnostic validation
- Check for diagnostic or fault indications before connecting the controller to live propulsion or machinery equipment.
- Validate communication using the correct protocol and service equipment.
- Use a calibrated digital multimeter or equivalent test instrument to verify supply conditions.
- Do not jumper unknown I/O or communication pins merely to force the controller into an apparent RUN state.
5. Extended heat run
- Run the replacement under controlled bench conditions for approximately 24 hours when practical.
- Monitor startup stability, communications, supply current, and thermal behavior.
- Record failures rather than clearing alarms and continuing the test.
6. Final preparation
- Record model, RR part number, serial number, PIC revision, firmware/configuration information, and memory-card status.
- Seal the unit in ESD-safe packaging.
- Include connector protection and desiccant for long-distance marine shipment where appropriate.
- Mark the package with the exact replacement identification so warehouse personnel do not substitute a visually similar controller.
Field Engineer’s Pitfall Guide
❗ Firmware/PIC mismatch is not a cosmetic issue.
A replacement controller can have threct designation yet still require the correct application/configuration and PIC revision. Current records identify PIC Code Rev. 2.2, so record this before accepting a substitute. Do not downgrade or alter controller software simply because the hardware powers up.
❗ Do not assvery has the same memory configuration.
One current inventory listing explicitly identifies the controller as “without memory card.” That matters because the controller hardware and the vessel application are not necessarily the same thing. A bare controller should not automatically be treated as a ready-to-run replacement.
❗ Connector population and backplane compatibility must be checked physically.
Marine automation cabinets accumulate revisions over long service lives. Before installation, compare connector locations, populated interfaces, revision markings, and wiring against the removed controller. A reseller’s generic port description is not a substitute for the vessel’s wiring diagram.
Intent-Driven FAQ
Is the Rooyce still available from the OEM?
The .0101 is listed as discontinued by manufacturer in Radwell’s current product record, so maintenance sourcing generally involves existing inventory, surplus, tested used units, or specialist marine spare channels.
What is the correct part n for ?
The strongest matching records identify RR Part No. 000068308. They also identify H6045/433 MHz and PIC Code Rev. 2.2. Some secondary listings show other numbers against the .0101 designation, so the physical nameplate and vessel documentation should take precedence.
Does include the vessel’s application memory?
Not necessarily. Inventory records specifically show .0101 units sold without a memory card. Treat memory-card inclusion as a separate purchasing requirement and verify the original vessel configuration before ordering.
Can I instalther as a direct replacement?
Only after confirming the hardware revision, PIC/firmware information, memory configuration, connector population, and vessel application. Physical fit alone is not enough for a marine controller tied into propulsion, machinery, or integrated vessel automation.
What processor information is associwith ?
Matching inventory records identify the controller as H6045 / 433 MHz. This is useful for identification, but it should not be interpreted as a complete specification of the controller’s application software or control-cycle performance.
the a generic PLC I/O module?
No. Available records consistently identify it as a marine controller, rather than a conventional standalone digital or analog I/O card. The correct replacement strategy therefore depends on the complete marine automation architecture.
What warranty should a buyer expect?
Warranty depends entirely on the seller and condition. Do not assume an OEM warranty simply because the listing says “new” or “factory sealed.” For example, current third-party inventory records explicitly distinguish seller-backed warranty from factory warranty. Confirm the exact written coverage, DOA terms, repair/replacement conditions, and return period before purchase.
Buyer Verification Checklist
Before purchasing a , request:
- Clear nameplate photograph
- RR Part Number confirmation
- Serial number
- PIC Code revision
- /433 MHz identification
- Memory-card status
- Connector/interface photographs
- Hardware revision
- Power-up test evidence
- Communication test evidence, if available
- Exact warranty terms
- Confirmation whether the unit is OEM surplus, used, refurbished, or repaired
For an obsolete marine controller, those details are more valuable than a generic claim of “100% compatible.” The safest procurement path is an exact identification match followed by configuration and functional verification.
