Product Overview
The Emerson KJ4001X1-HA1 Horizontal LocalBus Cable Extender Assembly is a DeltaV system hardware accessory used for extending LocalBus connections between Emerson DeltaV I/O components installed in horizontal cabinet arrangements.
In modular DeltaV control architectures, LocalBus provides communication between I/O interface components and connected modules. When system layouts require additional spacing between hardware assemblies, the KJ4001X1-HA1 helps maintain communication continuity by extending the LocalBus connection path.
This extender assembly is typically used in control cabinets where I/O carriers, power carriers, and interface components need to be arranged with flexible spacing. It supports modular cabinet design, simplifies hardware installation, and provides a practical solution for expanding DeltaV I/O system configurations.

Product Features
The Emerson KJ4001X1-HA1 provides flexible LocalBus extension capability for DeltaV modular hardware installations.
Key features include:
- Emerson DeltaV compatible LocalBus extender assembly
- Model KJ4001X1-HA1
- Horizontal installation configuration
- Supports extended cabinet hardware arrangements
- Maintains communication between connected DeltaV assemblies
- Enables flexible placement of I/O components
- Helps simplify control cabinet layout design
- Suitable for modular DeltaV system expansion
- Supports reliable hardware interconnection
- Designed for industrial process control environments
The extender assembly provides the connection flexibility required when standard carrier positioning cannot meet cabinet layout requirements.
Working Principle
The KJ4001X1-HA1 functions as a physical extension interface for the DeltaV LocalBus communication network.
Typical connection structure:
DeltaV Carrier / I/O Assembly → Horizontal LocalBus Extender → Additional Carrier Assembly → DeltaV I/O Modules
Operating process:
- The extender assembly is installed between compatible DeltaV LocalBus connection points.
- The LocalBus communication path is extended horizontally within the cabinet.
- Connected I/O assemblies continue exchanging system data through the DeltaV hardware architecture.
- The controller communicates with distributed I/O modules for process monitoring and control.
The extender assembly does not perform signal conversion or control processing. Its primary purpose is maintaining communication connectivity between separated DeltaV hardware sections.
Role in DeltaV System Architecture
The KJ4001X1-HA1 is an infrastructure component that supports flexible DeltaV I/O system installation.
| Component | Function |
|---|---|
| LocalBus Cable Extender | Extends hardware communication distance |
| I/O Carrier | Provides module mounting structure |
| Power Carrier | Supplies module power connection |
| I/O Modules | Process field signals |
| Controller | Executes automation logic |
| Terminal Blocks | Connect field devices |
By extending the LocalBus connection, the module arrangement can be adapted to different cabinet designs and installation requirements.
