Emerson DeltaV KJ4010X1-BG1 12P0830X072 Right LocalBus Extender

Description

The Emerson DeltaV KJ4010X1-BG1 (12P0830X072) is a Right LocalBus Extender designed for the DeltaV scalable process control system. This module is essential for expanding the LocalBus backplane, enabling the interconnection of multiple I/O carriers across different rows or enclosures within a control cabinet. It ensures high-speed data synchronization and maintains power distribution integrity across the extended bus, providing the necessary flexibility for large-scale distributed control system (DCS) deployments.

Features

• Facilitates physical expansion of the DeltaV LocalBus backplane.
• Enables signal transition between carrier rows via dedicated cable assemblies.
• Designed for high-availability industrial environments including oil, gas, and chemical processing.
• Rated for operation in hazardous locations (Zone 2).
• Conformal coating compliant with ISA-S71.04-1985 Class G3 for protection against corrosive contaminants.

Applications

This module is used in industrial automation environments where the I/O count requires multiple carrier rows. It is commonly deployed in oil refineries, chemical processing plants, and mining operations where robust, reliable communication between the controller and remote I/O is required.

Technical Specifications

Installation Guidelines

• Ensure all power is de-energized before connecting or disconnecting LocalBus cables.
• The module must be installed as the physical termination point on the right side of a carrier row.
• Verify that the total combined length of I/O carriers and LocalBus extenders does not exceed 6.5 meters to maintain signal timing integrity.
• Handle with standard ESD precautions to prevent damage to internal circuitry.
• Ensure the environment meets the specified temperature and humidity ranges for optimal performance.

Compliance and Certifications

The KJ4010X1-BG1 is certified for use in hazardous atmospheres, specifically II 3 G, Nemko 02ATEX431U, and EEx nA IIC T4, making it suitable for Zone 2 installations.

FAQ
