Emerson KJ4003X1-BH1+KJ4003X1-BH5 Single-Carrier Extender Cable

High-Integrity Carrier Extension for DeltaV System Architecture

The Emerson KJ4003X1-BH1 + KJ4003X1-BH5 Single-Carrier Extender Cable is designed to extend communication and power pathways between DeltaV I/O carriers, enabling flexible cabinet expansion in distributed control system (DCS) architectures. This combination supports modular system layouts where multiple carriers must be interconnected while maintaining stable LocalBus performance and industrial reliability.

With configurable cable length options, this extender solution is widely used in large-scale process automation systems requiring scalable I/O deployment.

Typical applications include:

• Emerson DeltaV Distributed Control Systems (DCS)
• Horizontal and vertical I/O carrier expansion
• Oil & gas production and refining systems
• Petrochemical and chemical processing plants
• Power generation and utility automation
• Industrial manufacturing control systems
• Complex modular automation cabinet architectures
