Product Overview
The Emerson KJ4001X1-GA1 Local Bus Right-Hand Extension Cable is a connection accessory used in Emerson DeltaV distributed control systems (DCS) for extending the local bus communication path between DeltaV hardware components. It provides a physical communication link that allows I/O carriers, interface components, and related modules to be installed in expanded cabinet configurations.
In modular DeltaV architectures, local bus connections are responsible for communication between system hardware assemblies. When the distance or arrangement between carrier sections requires additional connection length, the KJ4001X1-GA1 extension cable provides a practical solution for maintaining communication continuity.
This cable is commonly used with DeltaV I/O carriers, power carriers, terminal blocks, and interface components. It helps engineers create flexible cabinet layouts while maintaining stable communication between distributed hardware modules.

Working Principle
The KJ4001X1-GA1 works by extending the local bus communication connection between DeltaV hardware components.
Typical connection structure:
DeltaV Carrier Assembly → Local Bus Extension Cable → Additional Carrier / Interface Assembly → I/O Modules
Operating process:
- The cable is connected between compatible DeltaV hardware assemblies.
- The local bus communication path is extended through the cable connection.
- Connected modules continue exchanging system information through the DeltaV architecture.
- Controllers communicate with installed I/O components for process monitoring and control.
The cable does not perform signal processing or control operations. Its primary function is to maintain a stable physical communication path between system hardware components.
Role in DeltaV System Architecture
The Emerson KJ4001X1-GA1 is used as an infrastructure component within modular DeltaV I/O installations.
| Component | Function |
|---|---|
| Local Bus Extension Cable | Extends hardware communication path |
| I/O Carrier | Provides module mounting |
| Power Carrier | Provides module power connection |
| I/O Modules | Process field signals |
| Controller | Executes control logic |
| Terminal Blocks | Connect field instruments |
By extending the local bus, the cable allows larger and more flexible DeltaV cabinet configurations.
