Product Overview
The Emerson KJ4002X1-BF3 Horizontal Carrier Extension Cable is a high-reliability carrier interconnection cable developed for the Emerson DeltaV™ Distributed Control System (DCS). Designed to extend communication and interconnection between compatible DeltaV carrier assemblies, the cable enables flexible cabinet layouts while maintaining dependable local bus communication and electrical continuity across modular automation systems.
The KJ4002X1-BF3 features a 1.2-meter cable length, providing engineers with additional installation flexibility when connecting horizontally mounted DeltaV I/O carriers or expansion assemblies. It simplifies cabinet design by allowing greater separation between hardware components without compromising communication reliability or system integrity.
Manufactured using industrial-grade materials, the cable is designed to withstand vibration, electrical noise, temperature variations, and continuous operation in demanding industrial environments. The pre-terminated connectors ensure fast installation while minimizing wiring errors and reducing commissioning time.
With a shipping weight of approximately 3 kg, the KJ4002X1-BF3 is suitable for new DeltaV installations, system upgrades, cabinet expansion projects, and replacement applications requiring reliable carrier-to-carrier communication.
Typical industries include oil and gas, petrochemical processing, chemical manufacturing, power generation, pharmaceutical production, food and beverage processing, mining, pulp and paper, and water and wastewater treatment.
