Product Profile: ABB UNS 0890A‑P (3BHE018297R0002)
Product Introduction
The UNS 0890A‑P is a processor / control module in ABB’s automation product line. It is used in high‑level control systems, particularly in converter, excitation, or measurement systems where precise processing, diagnostics, and communication with other modules are required.
This “P” version (often referred to as UNS 0890A‑P V2) is a refined version of the module, offering updated firmware, reliability improvements, and interface enhancements. It typically resides in control cabinets or system chassis, acting as a central brain for measurement, feedback, and control coordination.
It is designed to handle real‑time signal processing, internal data routing, and communication with lower-level hardware and higher-level control layers.
Technical Specifications
Below is a table of the known and reasonably inferred specifications of UNS 0890A‑P:
| Parameter | Specification / Value |
|---|---|
| Model | UNS 0890A‑P |
| Part Number | 3BHE018297R0002 |
| Module Type | Processor / Control Module |
| Series / Family | UNS series (Excitation / Measurement / Control modules) |
| Dimensions (W × H × D) | 180 mm × 82 mm × 480 mm |
| Weight | 0.66 kg |
| Operating Temperature | –20 °C to +60 °C (typical) |
| Storage Temperature | –40 °C to +85 °C |
| Humidity Range | 5% to 95% non‑condensing |
| Mounting / Form Factor | Chassis or rack mounted within control cabinets |
| Power Supply | Standard control voltage (e.g. 24 V DC) |
| Protection / Enclosure Rating | IP20 (internal module) |
| Primary Functions | Signal measurement, excitation, data processing, communication |
| Interface / Communication | Supports internal module buses and higher-level system links |
Notes / Explanation:
-
The dimensions (480 × 82 × 180 mm) and weight (0.66 kg) are obtained from a published industrial module listing.
-
In more compact listings, a secondary source shows 135 × 140 × 140 mm and weight 0.26 kg for a “processor module” listing.
-
The discrepancy suggests variants or module styles (perhaps “core board only” vs full module). The larger size/weight likely refer to the full enclosure version.
-
Operating and storage ranges are standard for such control modules.
-
Power supply, interfaces, and protective rating are typical for internal control modules.
Applications
-
Excitation & measurement systems in power generation
-
Converter / power electronics control systems
-
Heavy industrial automation requiring precise feedback and control
-
Integration in advanced DCS / SCADA / control networks
