Product Overview

The KJ4002X1-BF2 (Part Number 12P3866X012) is a specialized local bus expansion component for the Emerson DeltaV™ M-series I/O Subsystem. This high-integrity extender cable is engineered to bridge communication between I/O carriers, allowing the DeltaV local bus to span across multiple rows or separate sections within a control cabinet. By maintaining high-speed signal continuity, it enables the controller to manage expanded I/O counts without compromising data throughput or timing accuracy. It is an essential hardware element for modular DCS architectures requiring physical separation between the controller and remote I/O banks.

Hardware Parameters and Technical Characteristics

• Function: Local I/O bus extension for DeltaV M-series carriers.

• Wiring Composition: Premium high-strand copper conductors optimized for low-impedance data transmission.

• Signal Integrity: Industrial-grade shielding to mitigate Electromagnetic Interference (EMI) in high-density cabinet environments.

• Connector Interface: Robust industrial connectors designed for vibration-resistant seating and rapid installation.

• Thermal Range: Rated for extreme operational temperatures ranging from -40°C to +70°C.

• Compliance: Certified to CE and UL standards for global industrial safety and regulatory adherence.

• Physical Weight: 0.5 kg.

• Dimensions: 136 cm (length) x 7 cm x 2 cm.

• Durability: Reinforced jacket material designed to withstand mechanical stress and chemical exposure common in factory environments.

Industrial Applications

The 12P3866X012 Bus Extender Cable is primarily utilized in large-scale Distributed Control Systems where I/O requirements exceed the physical capacity of a single carrier row. In Oil & Gas Refineries and Chemical Processing plants, it facilitates the connection of supplemental I/O carriers to the main controller bus, allowing for extensive monitoring of field instrumentation across multi-cabinet suites. It is also a critical component in Power Generation and Water Treatment facilities undergoing system upgrades, as its flexible design permits engineers to reorganize I/O layouts and expand system capacity without reconfiguring the core network architecture.
