Description
ALSTOM VP325-02X – VP3xx-series rack module for power plant and substation control/protection
The ALSTOM VP325-02X is a plug-in module from the VP3xx family used in legacy ALSTOM/AREVA control and protection panels. From my experience, you’ll see it in turbine-generator auxiliaries, switchgear automation, and retrofit panels where deterministic trip logic and conditioned I/O are required. It’s typically installed in a VP-series rack and powered via the system backplane, making it a straightforward drop-in when you’re maintaining existing cabinets or planning a like-for-like replacement.

Key Features
- VP3xx rack form factor – Slides into the ALSTOM VP-series chassis and locks with front-panel screws for stable contact integrity.
- Backplane-powered – No local power feed; the module is supplied by the host rack, which simplifies wiring and service.
- Deterministic signaling – In many cases, the VP325-02X participates in low-latency trip/permit paths through the rack bus for reliable interlocking.
- Industrial-grade build – Typically conformal-coated PCB and robust front connectors for use in utility environments with dust and vibration.
- Status indication – You might notice clear front-panel LEDs and labeled test points that make troubleshooting faster during planned outages.
- -02X revision – The suffix indicates a specific hardware/firmware build; matching revisions across the cabinet usually avoids nuisance compatibility issues.
- Service-friendly – Field teams often appreciate that it’s a direct replacement without cabinet rework; swap time is typically measured in minutes once the system is made safe.
“We keep two VP325-02X on the shelf. During a condenser maintenance window, we swapped a suspect card and verified logic in under 30 minutes. No wiring changes, no surprises.” – Maintenance engineer, combined-cycle plant

Where it fits and typical use cases
- As a spare or replacement in ALSTOM/AREVA VP-series panels for turbine-generator protection logic.
- Switchgear and substation automation cabinets that rely on VP3xx modular architecture.
- Retrofit and life-extension projects where keeping original form factor minimizes downtime and re-engineering.
Related or supporting products
- ALSTOM VP320-series modules – Similar VP3xx form factor; often used for complementary I/O or logic functions.
- ALSTOM VP330 / VP335 modules – In many cases provide processing or specialized I/O to pair with VP325-02X.
- VP-series rack chassis and system power supply – Required backplane and supply for correct operation.
- Front cabling/terminal hardware – Replacement terminal blocks and labeled harnesses for quick swap-outs.
If you’re evaluating substitutes, it’s best to match the exact revision (-02X) for predictable interoperability with existing cards in the same rack.
Installation & Maintenance
- Cabinet environment – Install in a clean, dry, and ventilated control cabinet. Maintain ambient typically within 0–55°C and keep humidity non-condensing.
- Wiring – All signal and power are via the VP backplane. Verify slot assignment and keying before insertion; label any front connections if present.
- Safety – De-energize the rack or place the system in a safe state before handling. Use ESD protection and allow capacitors to discharge as per the service manual.
- Commissioning – After installation, check front LEDs, run built-in diagnostics if available, and validate logic paths during a controlled test.
- Routine maintenance – Periodically inspect connectors, clean dust with dry air, and reseat during planned outages. Firmware alignment should match the rest of the rack; update only with approved images.
Quality & Certifications
- Typically CE compliant for EU installations; UL/CSA applicability may depend on the panel build and production era.
- RoHS status can vary on legacy modules; many plants operate these under grandfathered exemptions.
- Warranty: 365-day coverage provided by us on supply; manufacturer’s original policy may differ based on sourcing.
If you can share your rack part number and the adjacent card revisions, we can double-check VP325-02X compatibility before shipment. One thing I appreciate is how smooth these replacements go when revisions are matched up front.
