Description
Product introduction
The Lyngsø Marine ZM411 is identified in supplier catalogs as a Gamma Micro CPU module for marine automation equipment. CPU modules perform processing and coordination tasks within their intended control architecture, but the exact control responsibilities of this particular ZM411 installation should be established from the vessel’s system documentation. It should not be treated as a general-purpose PLC CPU or assumed compatible with unrelated marine control platforms merely because they perform similar functions.
For marine maintenance teams, part identification is especially important when supporting older control equipment. The supplied designation, ZM411 271.149 319, appears close to a listed ZM411 271.149.319.08 catalog entry. The ZM411 is also marketed under the separate number family 962.002.800, with revision suffixes appearing in supplier listings. These references establish a relationship within the product family, but do not prove that every version is interchangeable. Before ordering a spare, compare the complete nameplate, board revision, connector layout, and the installed system’s configuration records.

Application scenarios and common pain points
- Marine automation maintenance: Replacing a suspected faulty CPU module in an existing Lyngsø Marine / STN Atlas control installation.
- Vessel service and overhaul: Preparing a spare module before a planned maintenance period to reduce downtime if the installed CPU fails.
- Legacy system support: Identifying suitable replacement stock when the original equipment generation is no longer routinely supplied.
- Spare-parts management: Recording the full module and revision numbers to avoid confusion between related catalog references.
The main risk is ordering a part based on the name alone. Marine equipment may have multiple revisions, system-specific configurations, and different firmware requirements. A replacement that physically fits may still fail to initialize or communicate correctly with the existing system.

Engineer’s guide: field pitfalls to avoid
- Verify the complete part number. Check whether the installed board reads
271.149.319,271.149.319.08, or another revision. Do not treat formatting differences as proof of equivalence. - Check system and firmware compatibility. Confirm the control-system generation, firmware requirements, and configuration procedure before installing a replacement CPU module.
- Request evidence for surplus stock. For new-old-stock or refurbished modules, request clear label photos, revision details, condition information, and test records. A visual inspection alone does not establish CPU functionality.
Frequently asked questions
Q1: What is the 271.149.319?
It is associated with the Lyngsø Marine / SAM Electronics Gamma Micro CPU module family used in marine automation systems.
Q2: Is 271.149.319 the complete part number?
It may be an abbreviated designation. A supplier lists 271.149.319.08, so check the installed label before ordering.
Q3: Is 962.002.800/E the same as 271.149.319?
Both are listed under the CPU-module family, but the available listings do not establish that the numbers are fully interchangeable. Verify the hardware revision and system documentation.
Q4: What voltage does the module require?
I could not verify the exact working voltage for the supplied variant. Use the relevant equipment manual or the original board documentation rather than assuming a standard supply voltage.
Q5: Can it replace a failed PLC CPU from another manufacturer?
No compatibility should be assumed. The belongs to a specific marine automation platform and should be replaced only with a documented compatible part.
Q6: What should be checked before purchase?
Confirm the full part number and suffix, hardware revision, connector layout, system generation, firmware requirements, and the supplier’s functional test evidence.
Q7: Is the still available from the original manufacturer?
Current original-manufacturer availability and support status could not be confirmed from the available listings. Check actual stock status and whether the offered unit is new, unused surplus, repaired, or refurbished before committing to a purchase.
