Warranty: 365 days
Delivery: 1 week when in stock; no more than one month at the latest
Payment: 50% advance payment; full payment before delivery
Express options: FedEx, UPS, DHL
Testing & packing: function-tested prior to dispatch; ESD-safe and shock-protected packaging
OEM form factor: Plug‑in board engineered for Alstom racks, easing field replacement and minimizing wiring changes.
Revision SA44667.C: Clear traceability for matching plant configuration and redundant pairs.
Backplane powered: Draws power from the system backplane, so no extra field supply routing is needed.
Service-friendly: Front access for insertion/removal; typically used with captive screws or a card handle for secure seating.
Stable installed base: Helps extend life of legacy Alstom control cabinets where a full upgrade isn’t practical.
Quality screened: Units are inspected and function-tested prior to shipment to reduce commissioning time.
| Brand / Model | ALSTOM NRD108033 / 8RDC44667G01, Rev. SA44667.C |
| HS Code | 853890 (Parts for switchgear/industrial control equipment) |
| Power Requirements | Powered via system backplane; typical logic rails in many Alstom racks (e.g., 5 VDC and auxiliary rails) supplied by the cabinet PSU |
| Dimensions & Weight | Plug‑in PCB module for rack installation; weight typically under 0.6 kg |
| Operating Temperature | 0 to 55 °C typical for cabinet-mounted control electronics |
| Signal I/O Types | Interfaces to controller via proprietary backplane; field I/O routed through the rack/terminal units (no direct field terminations on the module in most cases) |
| Communication Interfaces | Backplane bus to host controller; external comms handled by the system rack or CPU as configured |
| Installation Method | Rack-mounted plug‑in card; insertion via front panel with securing screws/handle |
This module is typically found in:
Power generation plants (steam/gas turbine auxiliaries, balance‑of‑plant skids)
Industrial process control cabinets with legacy Alstom control racks
Utility and plant sub-systems where Alstom backplane-based I/O/communication modules are installed
Reliability: Field-proven module format used across many Alstom cabinets; reduces risk during changeouts.
Compatibility: Matched part number and revision (SA44667.C) to align with existing firmware and rack hardware.
Cost savings: Extends life of legacy systems without immediate migration to a new platform.
Technical support: Help with part identification, cross-revisions, and pre-shipment testing reports if needed.
Cabinet environment: Install in a clean, ventilated control cabinet. Maintain ambient within 0–55 °C and avoid condensation.
ESD handling: Use grounding straps and ESD-safe work practices; keep the module in its antistatic packaging until installation.
Power-down: Unless the rack supports hot‑swap for this slot, power down and isolate the cabinet before removal/insertion.
Seating & fastening: Slide the card along the guides until fully mated with the backplane; secure using front panel screws/handle.
Revision matching: Match SA44667.C with the partner module/slot where required; verify firmware compatibility during commissioning.
Routine care: Periodic dust removal with dry air, check connector wear, and keep firmware/config backups for disaster recovery.
Manufacturing and repair typically aligned with ISO 9001 quality processes
CE conformity applies at the cabinet/system level; component-level marking varies by revision
RoHS status may vary for legacy revisions; many earlier parts are non‑RoHS by design
Warranty: 365 days from delivery
Commonly paired with the original Alstom rack backplane, system power supply, and field termination units in the same cabinet. If you’re planning a staged refresh, we can help check slot mapping, recommended spares, and compatible backplane power rails for this module family.
