Emerson KJ4002X1-BF2 12P3866X012 Bus Extender Cable Assembly

Overview

Configured for bottom bus extension connection in the Emerson DeltaV system, the Emerson KJ4002X1-BF2 12P3866X012 (KJ4002X1-BF2 Bus Extender Cable Assembly) provides direct physical signal interconnection between system hardware components. This 1.40 m bottom extender cable assembly uses a dedicated cable structure for DeltaV controller and I/O subsystem installation.

Hardware Specifications

DCS Bus Interconnection and Signal Routing Characteristics

The KJ4002X1-BF2 cable assembly provides a physical extension path for Emerson DeltaV system bus connections. It maintains electrical continuity between connected hardware positions and supports cabinet-level installation layouts.

Furthermore, the assembly uses stranded copper conductors with a 24-26 AWG gauge to provide signal transmission between compatible DeltaV hardware interfaces. The 300 V AC/DC voltage rating defines the insulation capability of the cable assembly under specified operating conditions.

The cable design supports controlled cabinet wiring practices. Therefore, installers should maintain proper cable separation from high-voltage power conductors to reduce electrical interference during system operation.

Frequently Asked Questions

Q: What is the primary function of the Emerson KJ4002X1-BF2 12P3866X012?
A: The KJ4002X1-BF2 is a bottom bus extender cable assembly designed to provide physical bus extension and interconnection within compatible Emerson DeltaV system hardware configurations.

Q: Does the KJ4002X1-BF2 require an external power supply?
A: No. The cable assembly is a passive interconnection component and does not contain active electronic circuits or require external power input.

Q: What installation practices should be considered for this cable assembly?

Field Installation Guidelines

1. Verify the cable part number before installation to confirm compatibility with the intended Emerson DeltaV hardware assembly.
2. Install the cable according to the cabinet wiring layout and maintain proper bend radius to prevent mechanical stress on connectors and conductors.
3. Route the cable separately from high-current AC power lines, motor cables, and sources of electromagnetic interference.
4. Ensure connectors are fully seated and mechanically secured before system startup.
5. Inspect the cable jacket, terminals, and connection points during maintenance activities to identify physical damage or contamination.
