ALSTOM V4561983-0100 / V4559856 – Railway Signaling Control Module for Safety-Critical Racks
The ALSTOM V4561983-0100 paired with V4559856 is an OEM board-level module used in railway signaling cabinets and onboard control racks. From my experience, this model is typically deployed in interlocking or wayside logic bays where stable 24 VDC power, galvanic isolation, and robust I/O are essential. Customers choose it as a fit‑form‑function replacement to keep legacy and current Alstom architectures running with minimal downtime. You might notice that the plug‑in design makes changeouts straightforward—often a matter of minutes rather than hours.

Notes: Exact pinout and backplane allocation depend on the rack type and revision of V4561983-0100 / V4559856. We help verify compatibility by part and serial.
Application Fields
- Wayside interlocking racks for route control and signal aspect management
- Level crossing controller cabinets (logic and I/O aggregation)
- Point machine control and status monitoring
- Depot and yard signaling panels, junction automation
- Onboard subsystems where Alstom rack modules are specified
A metro operator in Europe shared that replacing this board restored turnout control within 30 minutes, which seems to be the kind of downtime reduction most maintenance teams aim for.
Advantages & Value for Procurement
- Reliability first: Railway‑grade components and isolation for harsh EMC environments.
- Compatibility: Fit‑form‑function match helps avoid costly redesign or requalification.
- Faster recovery: Plug‑in swap reduces Mean Time to Repair and keeps routes open.
- Lifecycle savings: Extend installed base life and defer large capital upgrades.
- Traceable sourcing: Documentation and test reports available for maintenance records.
- Technical support: Assistance with part verification, rack slot mapping, and commissioning tips.
Installation & Maintenance
- Cabinet environment: Install in a clean, ventilated signaling cabinet; keep ambient within the specified range and avoid moisture ingress.
- Power & wiring: Use regulated 24 VDC; verify polarity and residual ripple. Torque terminal screws to spec and observe correct backplane slotting.
- ESD & safety: Wear ESD protection; isolate power before insertion/removal. Confirm earth/PE continuity and shielding per EMC practice.
- Commissioning checks: Validate I/O mapping, loop integrity, and interlocking logic; record firmware/hardware revision if applicable.
- Routine maintenance: Inspect connectors every 6–12 months, clean dust with dry air, and re‑seat if vibration loosening is suspected. Firmware updates apply only where the variant includes programmable logic.
- Spares strategy: Keep one tested spare per critical rack bay to minimize service disruption.
Quality & Certifications
- Manufactured under ISO 9001 quality systems (typical for Alstom production)
- Compliance on many variants with EN 50155 (railway electronic equipment), EN 50121 (EMC), and IEC 61373 (shock & vibration)
- CE marking where applicable; RoHS status may follow rail exemptions depending on build year
- 365‑day warranty; supplied fully tested with inspection documentation available on request
Related Supporting Components
- Mating backplane connectors and rack carriers for Alstom signaling bays
- Terminal block kits and shielded harness assemblies for I/O field wiring
- 24 VDC regulated power supplies and surge protection tailored for wayside cabinets
