Genuine ABB spare – Designed for ABB excitation/PEC control racks, ensuring mechanical and electrical fit without cabinet rework.
Backplane‑integrated – Interfaces via the system backplane, so there’s typically no field terminal rewiring during swaps.
Stable operation in utility environments – Built for continuous duty in power generation and converter cabinets.
Service-friendly design – Front-panel access for module replacement and labeling; reduces downtime during planned outages.
Lifecycle continuity – In many cases compatible with existing firmware/hardware revisions, helping keep legacy lines running.
| Brand / Model | ABB UNS0122A-P (3BHE042393R0101) |
| HS Code | 8538.90 (Parts for control panels/equipment) |
| Power Requirements | Supplied via system backplane (rack typically powered by 24 VDC) |
| Signal I/O Types | Internal backplane signals; no direct field terminals on the module |
| Communication Interfaces | Proprietary ABB rack/backplane interface (diagnostics via system tools) |
| Installation Method | Plug-in module for ABB excitation/PEC control rack; front-panel retained |
| Operating Temperature | 0…55°C in control cabinets (typical) |
| Dimensions & Weight | Plug‑in rack card; 19″ subrack format (compact/lightweight, typical) |
Plants usually deploy the UNS0122A-P in:
UNITROL-based excitation systems in hydro, gas, or steam power generation.
PEC/drive and converter cabinets in metals, pulp & paper, and process industries.
Lifecycle service projects where a drop-in ABB spare keeps legacy systems online.
One thing I appreciate is how it helps maintenance teams standardize spares across multiple units. A customer in a hydro station told us a swap took under 30 minutes during a planned outage, with no field wiring changes—just alignment of firmware notes and a quick health check in the HMI.
Reliability – ABB rack modules are built for continuous-duty applications and typically handle cabinet conditions well.
Compatibility – Form-fit-function replacement reduces engineering changes and keeps system qualification straightforward.
Cost savings – Shorter outage windows and minimal rewiring translate into real maintenance savings.
Supportability – We help match revisions, confirm rack compatibility, and document the swap procedure.
Cabinet environment – Install in a clean, ventilated 19″ control cabinet; avoid dust ingress and vibration hotspots.
Power and grounding – Verify rack 24 VDC supply quality and cabinet grounding; stable backplane power reduces nuisance trips.
Wiring – No field terminals on the module; ensure the backplane connectors are clean and fully seated.
Safety – De-energize the rack (unless the system procedure allows controlled hot-swap), follow ESD protection, and label the removed unit.
Routine care – Periodic visual inspection, dust removal with dry air, and firmware/config backups. Keep spare boards in antistatic bags in a dry store.
CE compliant for industrial control use (typical for ABB rack modules).
RoHS conformity in most markets.
Manufactured under ISO 9001 quality systems.
Warranty: 365 days; replacement or repair per test outcome.
We typically support adjacent ABB modules used in the same racks (e.g., companion UNS-series boards and UNITROL rack power/communication units). If you share your current rack BOM or a cabinet photo, we can verify cross-compatibility and suggest on‑hand spares to reduce lead time exposure.
