A formal SIRE inspection record identifies V4555724-0100 as the control unit of a SIRE-2-3-4-1 system. The same record identifies V4555692-0100 as the power cabinet, V4562076-0200 as the converter unit, and V4562061-0200 as the high-voltage unit. The documented system had software version 8.9.0 at inspection.
Product Introduction
The ALSTOM V4555724-0100 is the control unit used within an ALSTOM SIRE power-control system. Its documented system position is significant: it works as part of a larger SIRE installation that includes the power cabinet, converter, and high-voltage section rather than functioning as a conventional standalone PLC I/O module.
For maintenance and procurement teams supporting older ALSTOM equipment, the V4555724-0100 should therefore be treated as a system-specific control component. Matching the complete part number and the SIRE system configuration is more important than relying on generic descriptions such as “analog module” or “industrial control board.”

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
When an older SIRE installation develops a control fault, the controller itself is only one part of the diagnostic chain. The power cabinet, converter, high-voltage section, wiring, and system software all interact. Replacing V4555724-0100 without checking these interfaces can result in a board that powers up but does not restore the original system function.
Typical Applications
- ALSTOM SIRE power-control systems
- Industrial high-voltage power-processing equipment
- SIRE converter-system control
- Legacy ALSTOM power-system maintenance
- Planned replacement of obsolete SIRE control hardware
Technical Pitfalls
- Do not classify it as a generic PLC I/O module. The strongest documentary evidence identifies specifically as the SIRE control unit.
- Verify the complete SIRE configuration. The documented installation combines the control unit with dedicated power, converter, and high-voltage assemblies. Confirm these associated part numbers before approving a replacement.
- Check software compatibility. The referenced SIRE installation records software version 8.9.0. A replacement controller should be checked against the software and configuration requirements of the actual installation rather than assumed compatible solely because the hardware part number matches.
- Do not rely on unsupported electrical specifications. Public secondary listings give conflicting claims for voltage, current, I/O count, communication protocols, dimensions, and environmental ratings. Those figures should not be used in a procurement specification without the applicable ALSTOM documentation.
- Verify the physical assembly. Before ordering a legacy control unit, compare the board label, revision markings, connectors, mounting arrangement, and system cabinet documentation with the requested .
- Check the complete control chain after replacement. A successful power-up does not by itself prove that the converter-control sequence, protection functions, measurement channels, and system interlocks are operating correctly.

Procurement Note
For , I would specify the complete part number together with the SIRE system model, software version, and associated converter/high-voltage hardware. The strongest available evidence identifies it as the SIRE control unit, so descriptions calling it a generic analog-output, communication, or I/O module should be treated cautiously.
For an installed system, the safest replacement check is the nameplate/PCB marking plus the SIRE cabinet BOM. That is especially important for discontinued equipment where visually similar control assemblies may belong to different SIRE configurations.
