The Emerson KJ4002X1-BF1 DeltaV Bottom Extender Cable Assembly is an interconnection component used within Emerson DeltaV M-Series system hardware. It belongs to the carrier and LocalBus interconnection layer and is intended for installations where the physical arrangement of DeltaV hardware requires an extended connection between compatible system sections.
Unlike field cables that connect sensors or actuators to individual I/O channels, the KJ4002X1-BF1 serves a system-level interconnection function. Its application is associated with the carrier structure and the arrangement of DeltaV control-system hardware inside the cabinet.
The bottom extender configuration distinguishes this assembly from other extender cable variants. For replacement or system expansion, the carrier position, connection arrangement, cable routing, and required cable length should all be considered before installation.

The KJ4002X1-BF1 is intended for DeltaV installations requiring a bottom-position extender connection within the system hardware arrangement.
Key characteristics include:
The KJ4002X1-BF1 extends the interconnection between compatible sections of the DeltaV carrier architecture.
A simplified arrangement is:
DeltaV Carrier Section → KJ4002X1-BF1 → Extended Carrier / System Section
The cable assembly maintains the required electrical connection between the associated hardware sections when they are not directly adjacent within the cabinet arrangement.
Its role is different from an ordinary instrumentation cable. The KJ4002X1-BF1 is associated with the system’s carrier-level interconnection rather than being assigned to an individual temperature transmitter, pressure transmitter, valve, or other field device.
Because this model is identified as a bottom extender cable assembly, its position and connection points should correspond to the applicable DeltaV hardware arrangement.
The KJ4002X1-BF1 occupies the system interconnection layer of a DeltaV M-Series installation.
Controller / Carrier → Bottom Extender → Extended Carrier Section → I/O Hardware
| System Layer | Typical Component | Function |
|---|---|---|
| Control Layer | DeltaV Controller | Executes control strategies |
| Carrier Layer | DeltaV Carrier | Provides module mounting |
| Interconnection Layer | KJ4002X1-BF1 | Extends the carrier-level connection |
| I/O Layer | DeltaV I/O Modules | Processes field signals |
| Interface Layer | Terminal Blocks | Connects field wiring |
| Field Layer | Sensors / Actuators | Measures and affects the process |
The extender assembly helps maintain the required system architecture when the carrier arrangement requires an extended connection.
The KJ4002X1-BF1 can be used in DeltaV-based industrial control installations where extended carrier interconnections are required.
| Application | Typical Use |
|---|---|
| Process Automation | DeltaV system expansion |
| Oil & Gas | Control cabinet interconnection |
| Chemical Processing | Extended carrier arrangements |
| Power Generation | Distributed control hardware installation |
| Water Treatment | Modular DeltaV system construction |
| Pharmaceutical Manufacturing | Control-system cabinet integration |
| Manufacturing | Extended automation hardware layouts |
| Plant Maintenance | Replacement of existing extender assemblies |
The specific application depends on the carrier configuration and physical arrangement of the DeltaV system.
The extender cable assembly should be installed with careful attention to its position and connection points.
Recommended checks include:
When replacing an existing extender assembly, recording the original cable routing and connection locations can help restore the system correctly.
The KJ4002X1-BF1 works together with other DeltaV control-system hardware.
| Component | Function |
|---|---|
| DeltaV Controller | Executes control strategies |
| DeltaV Power Supply | Provides system operating power |
| DeltaV Carrier | Provides module mounting and interconnection |
| KJ4002X1-BF1 | Provides bottom extender connection |
| DeltaV I/O Carrier | Supports I/O module installation |
| DeltaV I/O Modules | Interfaces with field signals |
| LocalBus Hardware | Supports system-level interconnection |
| Terminal Blocks | Provides field wiring termination |
| Field Wiring | Connects control hardware to field devices |
| Sensors / Actuators | Provides process measurements and control actions |
The extender assembly should be selected together with the carrier architecture and connected DeltaV hardware.
| Model / Product Family | Product Type | Typical Application |
|---|---|---|
| Emerson KJ4002X1-BF1 | DeltaV M-Series Bottom Extender Cable Assembly | Bottom carrier interconnection |
| Emerson KJ4002X1-BE1 | DeltaV M-Series Top Extender Cable | Top carrier interconnection |
| Emerson KJ4001X1-GA1 | DeltaV Local Bus Right-Hand Extension Cable | LocalBus extension |
| Emerson KJ4001X1-HA1 | Horizontal LocalBus Cable Extender Assembly | Horizontal system interconnection |
| Emerson KJ4002X1-BD2 | DeltaV 4-Wide Vertical Power/Controller Carrier | Vertical carrier arrangement |
Selection should be based on the carrier position, connection arrangement, required cable length, and existing DeltaV system architecture.
The KJ4002X1-BF1 is used for system-level carrier interconnection rather than direct connection to an individual field instrument. It forms part of the DeltaV hardware architecture between compatible system sections.
It is required when the DeltaV carrier arrangement calls for an extended connection at the bottom portion of the applicable system configuration. The physical layout should be checked before selecting the extender assembly.
The length should be selected based on the physical spacing and routing between the connected carrier sections. Proper routing should allow the cable to reach both connection points without excessive tension, bending, or unnecessary slack.
Inspect the KJ4002X1-BF1 connectors, cable condition, routing, and connected carrier interfaces. Loose connections, mechanical stress, damaged cable insulation, or contamination can affect system-level interconnection and should be ruled out during troubleshooting.
