Index Scope & Purpose
This index provides a system‑level reference for understanding how spare parts are classified within ABB OmniCore controller platforms.
It focuses on architectural grouping, functional roles, and identification logic, rather than product promotion or SKU listings.
The page is intended for orientation, maintenance planning, and technical reference, supporting integrators, maintenance engineers, and automation service providers.
Abstract Classification Framework
ABB OmniCore controller spare parts are identified and organized according to system architecture, not universal interchangeability.
| Classification Layer | Typical Scope | Identification Role |
|---|---|---|
| Functional Domain | Power, control, communication, interface | Defines system‑level role |
| Controller Platform | OmniCore (E10 / C30 / C90XT / V series) | Establishes architectural boundary |
| Assembly / Module Group | Drive units, boards, harnesses, interfaces | Groups replaceable system modules |
| Variant / Revision | Length, connector type, revision | Differentiates configuration only |
This abstraction explains how parts are structured, not whether they are interchangeable.
Core Functional Domains within OmniCore Controllers
1. Power & Drive Architecture
Components responsible for motion power distribution and drive control within the controller.

- DC bus distribution elements
- Power interface assemblies
2. Control & Communication Hardware
Modules handling logic processing and industrial communication.
- Fieldbus communication boards
- Network and protocol interface modules
- I/O connector assemblies
3. Internal Cables & Connections
Enable signal, data, and power transmission within the controller system.
- Internal wiring assemblies

Representative ABB OmniCore Controller Spare Parts (Reference Examples)
Note:Different OmniCore controller variants (E10, C30, C90XT, V series) use different internal layouts.
The following items are representative reference examples commonly encountered in service and maintenance contexts. They are shown for identification orientation only.
| Component Category | Part No. | Description |
|---|---|---|
| Drive Unit | 3HAC074966-001 | OmniCore deive unit (core module) |
| Harness DC‑BUS | 3HAC075385-001 | DC bus harness assembly |
| Harness EtherCAT | 3HAC075387-001 | Ethernet / EtherCAT harness |
| System 24V Harness | 3HAC075386-001 | 24 V system harness |
| Signal Cable Assembly | 3HAC078253-001 | Signal cable assembly |
| DeviceNet Board | 3HAC043383-001 | DeviceNet communications board |
| DeviceNet Harness 24V | 3HAC063601-001 | DeviceNet harness 24 V |
| DeviceNet Connection Harness | 3HAC062150-001 | DeviceNet connection harness |
| I/O Connector Assembly | 3HAC064901-001 | Single‑row mating connector (IP20) |
| FlexPendant Power Cable (7 m) | 3HAC064448-001 | FlexPendant power cable |
| FlexPendant Power Cable (3 m) | 3HAC064448-002 | FlexPendant power cable |
| FlexPendant Power Cable (30 m) | 3HAC064448-003 | FlexPendant power cable |
These examples anchor the abstract classification framework to real OmniCore controller components without converting the page into a product list.

Typical Maintenance & Service Contexts
OmniCore controller spare parts are typically referenced in the following scenarios:
- Controller refurbishment or lifecycle extension
- Replacement of damaged internal harnesses or connectors
- Communication troubleshooting (fieldbus or I/O level)
- Power distribution or drive‑related service operations
In all cases, controller model, hardware revision, and system configuration must be verified before part selection.
Identification & Compatibility Principles
When interpreting OmniCore controller part numbers:
- Part numbers indicate structural and functional classification, not guaranteed compatibility
- Controller platform alignment precedes variant or cable length considerations
- Similar numbering patterns may exist across different OmniCore generations
This index explains how parts are grouped and identified, not how to substitute them.
FAQ
Q: Does this index list all ABB OmniCore spare parts?
A: No. This page provides a system-level classification reference only. It does not enumerate all available OmniCore spare parts or variants.
Q: Are the part numbers shown here interchangeable across OmniCore controllers?
A: No. Part numbers reflect functional and architectural context. Compatibility must always be confirmed against the specific OmniCore controller model (E10, C30, C90XT, V series, etc.).
Q: Does inclusion in this index imply availability or sales intent?
A: No. All references are provided for identification and structural orientation purposes only. This index is not a product catalog or sales listing.
Q: Can this index be used as a replacement guide?
A: No. This index explains classification and system positioning, not substitution or replacement rules. Official ABB documentation should be consulted for service decisions.
