A customs record specifically identifies an N895314513L CRSA2/LPL-4.096 MBIT/S unit and describes it as a part intended for a metro rail project.
Technical caution: Publicly available documentation for this legacy ALSTOM part is limited. I would not assign unsupported voltage, connector, environmental, protocol, or channel specifications to the module without the original ALSTOM hardware documentation or a clear nameplate/board photograph.
Application Scenarios & Pain Points
A railway control spare has a different failure profile from a conventional PLC I/O card. Communication timing, board revision, system configuration, and the exact rack position can all matter; replacing the board without checking those details can create a second fault during commissioning.
- Metro rail systems: N895314513L records are specifically associated with metro rail project equipment, making this the strongest documented application area.
- Railway control and signaling: The CRSA2/LPL designation indicates its role within an ALSTOM-specific control/communication architecture rather than a general-purpose PLC platform.
- Data acquisition: Available product records describe N895314513L as a data acquisition module, supporting its use for collecting and transferring system information.
- Legacy system maintenance: Particularly relevant where the installed ALSTOM architecture remains in service and the original hardware needs to be retained.
Field note: Before replacing the board, photograph both the front label and PCB markings. The serial number and revision information can be just as useful as N895314513L when dealing with older railway equipment.

The Engineer’s Guide: Field Pitfalls to Avoid
Warning 1 — Do not treat as a generic data-acquisition card.
Its documented CRSA2/LPL designation is important. A generic board with similar acquisition terminology will not necessarily communicate with the existing railway system.
How to avoid it: Match the complete designation, CRSA2/LPL system identification, associated part number where applicable, and board revision.
Warning 2 — Verify the communication rate and system generation.
Available records identify a 4.096 Mbit/s /LPL configuration. A communication mismatch can manifest as a system-level fault rather than an obvious hardware error.
How to avoid it: Record the existing communication configuration and firmware/board revision before replacement. Do not change the communication generation during an emergency repair unless the system documentation explicitly permits it.
Warning 3 — Do not rely on a power-up test alone.
A board can illuminate or initialize correctly while failing under actual system communication conditions.
How to avoid it: For a refurbished unit, request functional testing appropriate to the actual ALSTOM system, including communication verification where possible. Check connectors and PCB contacts for oxidation, especially on equipment that has spent years in a rail-control cabinet.
Frequently Asked Questions (FAQ)
What is ALSTOM ?
is an ALSTOM legacy control-system module associated with the architecture. Available records identify it as a data acquisition/control module and associate it with a 4.096 Mbit/s communication configuration.
What does /LPL mean on ?
/LPL is the system designation associated with this particular ALSTOM module. It is more useful for compatibility checking than the generic description “control module,” because the module is intended to operate within a defined legacy architecture.
Is used in railway systems?
Yes. Available trade records specifically identify an /LPL-4.096 Mbit/s unit as a part intended for a metro rail project.
Is 1000418303 the same part as ?
Available ALSTOM equipment listings associate with 1000418303, so the latter is a useful cross-reference during procurement.
Still, verify the actual nameplate and board markings before treating the numbers as interchangeable procurement identifiers.
How should I verify a refurbished ?
Request:
- Clear front and rear photographs
- Complete marking
- PCB revision
- Serial number
- Connector condition
- Evidence of power-up testing
- Communication/system-level testing where available
- Warranty terms
- Actual lead time
For legacy railway electronics, system-level testing carries much more weight than a simple bench power test.
Can be replaced by another ALSTOM N895-series module?
Not without documentation. The N895 prefix alone does not establish electrical or functional compatibility. Different N895-series boards can serve different control, interface, or acquisition functions.
Before approving an alternative, compare the system architecture, board revision, communication interface, firmware, connector arrangement, and original ALSTOM part documentation.
What should I confirm before purchasing ?
Use the complete identification:
ALSTOM — /LPL — 4.096 Mbit/s — associated P/N 1000418303
Then verify the installed system, rack position, board revision, communication configuration, unit condition, testing scope, warranty, and delivery date.
For this particular legacy part, I would not approve a substitute based on the model number alone. The available public technical record is too limited; the installed board’s nameplate and system documentation should be treated as the final compatibility reference.
