The Emerson KJ4010X1-BG1 DeltaV Right LocalBus Extender Cable Assembly is a hardware connection accessory used in Emerson DeltaV distributed control system installations. It provides an extended LocalBus connection path for compatible DeltaV carrier and module assemblies, allowing greater flexibility when arranging control hardware within automation cabinets.
Unlike DeltaV controllers, I/O modules, and communication modules that perform processing or data exchange functions, the KJ4010X1-BG1 is a dedicated interconnection component. Its main purpose is to maintain the LocalBus connection between hardware sections when additional installation spacing or cabinet layout flexibility is required.
In DeltaV modular architectures, LocalBus extender assemblies help maintain communication continuity between connected hardware while supporting cabinet optimization. The KJ4010X1-BG1 is commonly applied in system expansion, hardware modification, and replacement projects where the original DeltaV installation structure needs to be maintained.

The Emerson KJ4010X1-BG1 provides LocalBus extension capability for DeltaV modular control hardware installations.
Key characteristics include:
The extender cable should be installed according to the DeltaV hardware arrangement and right-side connection requirements.
The KJ4010X1-BG1 functions as an extension link within the DeltaV LocalBus communication structure.
A simplified connection path can be represented as:
DeltaV Carrier / Module Assembly → KJ4010X1-BG1 LocalBus Extender → Extended LocalBus Connection → Additional Hardware
The cable assembly does not execute control logic or process field signals. Instead, it transfers LocalBus connection signals between compatible DeltaV hardware sections.
By extending the physical connection path, the cable assembly allows engineers to arrange DeltaV modules and carrier components according to cabinet space requirements while maintaining the required hardware communication path.
The KJ4010X1-BG1 belongs to the hardware interconnection layer of the DeltaV control architecture.
A typical structure can be represented as:
DeltaV Controller → Carrier Assembly → LocalBus Connection → I/O Hardware → Field Devices
| System Layer | Typical Function |
|---|---|
| DeltaV Controller | Executes control strategies |
| Carrier Assembly | Provides module installation structure |
| LocalBus Extender Cable | Extends hardware connection distance |
| DeltaV I/O Modules | Process field input and output signals |
| Field Devices | Provide process information |
The extender cable supports the physical connection between DeltaV system components.
The Emerson KJ4010X1-BG1 is suitable for DeltaV control systems requiring extended LocalBus connections.
| Application | Typical Use |
|---|---|
| Process Control Plants | Expanding DeltaV hardware layouts |
| Oil and Gas Facilities | Supporting distributed control installations |
| Chemical Processing | Maintaining modular control architectures |
| Power Generation | Connecting automation hardware sections |
| Pharmaceutical Systems | Supporting process control expansion |
| Manufacturing Plants | Flexible cabinet configuration |
| System Upgrade Projects | Extending existing LocalBus connections |
| Industrial Control Cabinets | Hardware connection management |
The actual application depends on the DeltaV system design and installation requirements.
Correct identification of the cable direction and installation position is important before replacement.
Recommended maintenance checks include:
If LocalBus communication faults occur, the extender cable, connectors, carrier assemblies, and connected modules should be checked together.
The KJ4010X1-BG1 operates together with other DeltaV hardware components.
| Component | Function |
|---|---|
| Emerson DeltaV Controllers | Execute control applications |
| DeltaV I/O Modules | Process field signals |
| DeltaV Carrier Assemblies | Provide module mounting structure |
| LocalBus Components | Provide internal hardware communication |
| Extender Cable Assemblies | Extend connection paths |
| Terminal Blocks | Organize field wiring |
| Power Supply Components | Provide system power |
| Control Cabinets | Provide installation environment |
These components form the hardware infrastructure of a DeltaV distributed control system.
| Model / Product Family | Product Type | Typical Application |
|---|---|---|
| Emerson KJ4010X1-BG1 | Right LocalBus Extender Cable Assembly | LocalBus extension |
| Emerson KJ4010X1-BF1 | Left LocalBus Extender Cable Assembly | LocalBus extension |
| Emerson KJ4002X1-BE1 | DeltaV M-Series Top Extender Cable | Carrier connection extension |
| Emerson KJ4002X1-BF1 | DeltaV Bottom Extender Cable Assembly | Carrier connection extension |
| Emerson KJ4003X1-BE1 | VerticalPLUS I/O Carrier Extender (Right) | Carrier expansion |
| Emerson KJ4003X1-BF1 | VerticalPLUS I/O Carrier Extender (Left) | Carrier expansion |
Selection should be based on DeltaV hardware type, installation direction, and required LocalBus connection arrangement.
The two models serve the same LocalBus extension purpose but are designed for different installation directions. The KJ4010X1-BG1 is used for right-side LocalBus extension arrangements.
A LocalBus extender allows compatible hardware sections to be positioned with greater flexibility while maintaining the required connection path between DeltaV components.
Engineers should confirm the carrier configuration, right-side connection requirement, cable routing, connector compatibility, and surrounding hardware arrangement.
Intermittent module availability, LocalBus communication errors, or loss of connection between hardware sections may indicate issues with the extender cable or related connections.
