Description
Lyngsø Marine IOM402 | Marine Input Output Module
Product Introduction
Marine automation spares need to match the installed system—not just the module’s general function. On legacy vessels, an incorrect I/O replacement can mean terminal remapping, control-system compatibility issues, and additional downtime during commissioning.
The Lyngsø Marine IOM402 (962.004.700) is an input/output module associated with SAM Electronics / STN Atlas marine automation equipment. Supplier records cross-reference it with SAM Electronics part number 271.149.244 and describe a 16-input, 12-solid-state-output configuration. These channel details should be verified against the physical module and applicable vessel documentation before use in a replacement specification.
For maintenance teams sourcing a legacy IOM402, confirm the complete part number, terminal layout, and host-system compatibility. The alternate references are useful for identification, but should not replace a nameplate and revision check.

Global Sourcing & Live-Test SOP
The following is a recommended qualification workflow—not a claim that the listed unit has been tested or refurbished.
Incoming Verification
- Confirm the IOM402 designation and part number on the module label.
- Record any serial number, hardware revision, and additional reference codes.
- Photograph the nameplate, terminals, connectors, and PCB.
- Inspect for corrosion, damaged terminals, contamination, and signs of unauthorized repair.
- Compare the received unit against the removed module and approved vessel documentation.
Authenticity and Traceability
- Record supplier, purchase order, stated condition, and shipment details.
- Check consistency between nameplate and PCB markings.
- Request traceability or service records where available.
- Flag part-number or revision discrepancies before installation.
Functional Qualification
- Test only in a compatible, approved marine automation setup.
- Verify module recognition and diagnostic status where supported.
- Validate digital inputs and solid-state outputs against an approved test procedure.
- Confirm electrical ratings and terminal assignments before applying test signals.
- Record test equipment, system configuration, and results.
Extended Run and Diagnostics
- Perform an extended operating run when supported by the test setup and applicable procedure.
- Record test duration, diagnostic results, and environmental conditions.
- Do not claim a 24-hour run unless supported by actual test records.
Configuration and Packaging
- Record hardware revision and relevant jumper or configuration settings, if present.
- Document known differences from the removed unit.
- Package using ESD-safe materials and adequate mechanical protection.
- Include test reports only when the corresponding tests have actually been completed.
Field Engineer’s Pitfall Guide
- ❗ Verify the full part number—not just . Cross-references include 962.004.700 and 271.149.244. Confirm the installed module’s label and revision before treating an alternate number as equivalent.
- ❗ Do not assume output ratings from the channel count. The 12 solid-state outputs require verification of voltage, current, load type, and protection requirements before field connection.
- ❗ Do not assume hot-swap capability. Follow the vessel’s approved maintenance procedure and confirm system isolation requirements before removing or installing the .
Intent-Driven FAQ
Q1: What is the Lyngsø Marine ?
It is a marine automation input/output module associated with Lyngsø Marine / SAM Electronics / STN Atlas equipment.
Q2: What part numbers are associated with the ?
Supplier references associate it with Lyngsø Marine 962.004.700 and SAM Electronics 271.149.244. A1012IOM402 is also listed as an additional reference. Confirm the physical label before ordering.
Q3: How many I/O points does the provide?
Supplier listings describe 16 digital inputs and 12 solid-state outputs. Verify the exact unit and applicable documentation before using these figures for wiring or design.
Q4: Is the compatible with all SAM Electronics or Lyngsø Marine systems?
No universal compatibility should be assumed. Confirm the host system, terminal layout, and applicable documentation for the installed vessel.
Q5: Can the be used as a direct replacement?
Only after matching the full part number, revision, electrical characteristics, terminal arrangement, and system compatibility against the removed module.
Q6: Is the hot-swappable?
Do not assume so. Follow the applicable OEM and vessel maintenance procedures before removing or inserting the module.
Q7: Does the part number guarantee a tested unit or warranty?
No. Condition, testing, warranty coverage, and included accessories must be confirmed from the seller’s specific offer and supporting records.
