Product Overview

The Emerson KJ4010X1-BG1 (Order Number: 12P0830X072) is a fundamental infrastructure component for the DeltaV™ M-series I/O Subsystem. This Localbus Right Extender serves as the physical and electrical bridge required to expand a DeltaV rail, allowing for the addition of further I/O interface carriers. By providing a secure connection on the right-hand side of a carrier bank, the module enables the horizontal scaling of the Distributed Control System (DCS) without requiring complex rewiring or system shutdowns.

This extender ensures that power and communication signals are transmitted consistently across the local bus to downstream I/O modules. It is an essential component for system integrators and plant engineers looking to increase point density or integrate new communication interfaces into existing DeltaV environments.

Technical Characteristics and Specifications

The KJ4010X1-BG1 is designed for high-availability industrial environments, prioritizing signal continuity and mechanical stability.

• Function: Localbus communication and power rail extension.

• Placement: Right-hand side of DeltaV M-series carriers.

• Bus Compatibility: Proprietary DeltaV Localbus for M-series hardware.

• Environmental Resistance: Ruggedized housing capable of withstanding standard industrial vibration and temperature variations.

  
  

• Installation: Tool-free mounting onto standard DIN rails; plugs directly into the adjacent carrier.

• Weight: 0.15 kg (approx. 0.33 lbs).

• Dimensions: 16.8 x 4.2 x 4.4 cm.

• DCS Integration: Fully transparent to DeltaV Explorer software; no specific firmware configuration is required for the extender itself.

Industrial Applications and Benefits

The Localbus Right Extender is utilized across heavy industries where DeltaV systems manage critical process variables.

• System Scaling: Allows for the incremental addition of 8-slot or 2-slot I/O carriers as process requirements grow.

• Retrofitting: Enables the integration of modern digital communication cards into legacy M-series racks.

• Space Optimization: The compact footprint allows for efficient use of cabinet space while maintaining the required clearance for heat dissipation.

• Maintenance Continuity: Facilitates a robust mechanical connection that prevents signal intermittent failure caused by cabinet vibration in power plants or chemical refineries.
