ALSTOM 12004-102-01 – Plug-in Control Board for Legacy Protection & Automation Systems
The ALSTOM 12004-102-01 is a factory-grade plug-in electronic board used in ALSTOM legacy protection, excitation, and substation automation platforms. From my experience, it’s typically deployed as a like-for-like spare to restore system availability without re-engineering the panel. You might notice that teams choose it when a MiCOM-era or ALSTOM Grid rack needs a direct replacement board that will slot into the existing backplane and boot with the established settings.
Company’s Order Placement Process and Guarantees
- Warranty period: 365 days
- Delivery time: 1 week for in-stock; no more than one month at the latest
- Payment terms: 50% advance payment, full payment for delivery
- Express delivery: FedEx, UPS, DHL
Key Features
- Genuine ALSTOM spare – Intended as a drop-in board for legacy ALSTOM/ALSTOM Grid systems, reducing retrofit risk.
- Backplane-powered – Typically draws regulated rails from the host chassis; no separate field PSU wiring needed.
- Stable, field-proven design – In many cases, conforms to the same BOM and firmware family used in installed bases.
- Fast return-to-service – Swap-and-commission approach shortens outage windows during maintenance.
- Conformal coating (varies by revision) – Many units include protective coating for industrial environments.
- Traceability support – Serial/revision labels help maintenance teams track installed revision levels.
Technical Specifications
| Brand / Model | ALSTOM 12004-102-01 |
| HS Code | 8538.90 (Parts for switchgear/control apparatus) |
| Power Requirements | Powered via host backplane (typical logic rails from chassis; no external supply) |
| Operating Temperature | Typically 0 to +55 °C (control room conditions) |
| Signal I/O Types | Internal analog/digital signaling over the system backplane; field I/O handled by terminal boards in the host system |
| Communication Interfaces | Interface to the host’s internal bus; protocol and address assignment managed by the host controller |
| Installation Method | Slide-in, plug-in board for the designated ALSTOM chassis slot; secured at the front panel |
Application Fields
- Substation protection and control (legacy ALSTOM/MiCOM platforms)
- Generator excitation and turbine control panels in power plants
- Industrial switchgear automation where ALSTOM Grid hardware is installed
- Refurbishment projects requiring form-fit-function replacements
Advantages & Value
- Risk reduction – Like-for-like spare minimizes engineering changes and re-qualification steps.
- Compatibility – Aligns with the original rack, wiring, and addressing—usually no panel rewiring.
- Cost control – Extends the service life of existing assets; delays costly system migrations.
- Downtime savings – Fast swap helps maintenance teams meet tight outage windows.
- Support – We assist with revision checks and basic fit/firmware compatibility before shipment.
One thing I appreciate is how straightforward the turnaround can be. A maintenance supervisor at a gas-fired plant told me they swapped a failed board with the 12004-102-01 during a short night shift—no wiring changes, just alignment, insertion, and a clean restart.
Installation & Maintenance
- Cabinet conditions – Install in a clean, dry, ventilated enclosure. Avoid conductive dust and condensation.
- ESD handling – Use wrist straps and antistatic bags. Power down and lock out before removal/insertion.
- Insertion – Guide the board along card rails; seat fully into the backplane and secure front fasteners evenly.
- Wiring – Field wiring remains on the host terminal blocks; confirm backplane connectors are free of bent pins.
- Firmware/config – If applicable, match firmware and configuration sets to the site baseline before energizing.
- Routine care – Periodic dust removal with dry air, connector inspection, and revision tracking. Functional checks during scheduled shutdowns.
Quality & Certifications
- Typically conforms with CE requirements as part of the complete protection/control system
- RoHS compliance for many revisions; legacy parts may vary by year of manufacture
- Manufacturing and testing aligned to utility/industrial standards commonly used by ALSTOM Grid
- Backed by our 365-day warranty and pre-shipment functional verification
Note: Exact electrical and mechanical characteristics can vary by hardware revision. If you share your installed system reference (rack type, firmware level, and adjacent module part numbers), we’ll validate fit and compatibility before you place the order.
