Product Overview
The Emerson KJ4002X1-BF2 is a LocalBus extender cable for horizontal I/O carriers. It connects compatible carrier assemblies within an Emerson distributed control system (DCS).
This cable provides a dedicated connection for LocalBus communication and power distribution. Its 1.2-meter length supports carrier interconnection in distributed cabinet layouts.
The cable features a 44-pin connector configuration. It supports LocalBus circuit power requirements of 12.6 VDC at 15 A.
For system designers and maintenance engineers, cable length and power compatibility are critical selection factors. The complete carrier and extender arrangement must remain within the specified maximum length.

Installation Guidelines
Correct installation protects the LocalBus interface and prevents electrical damage.
- Power Isolation: De-energize the system before disconnecting carriers or LocalBus extender cables.
- Hazardous Area Precautions: Never unplug the cable under power unless the area is confirmed safe.
- Length Restriction: Keep the combined I/O carrier and LocalBus extender length within 6.5 meters.
- Enclosure Interconnection: Install cables between separate enclosures inside conduit.
- Connector Inspection: Check connector alignment and contact condition before installation.
- Cable Routing: Avoid excessive bending, tension, and mechanical stress.
Engineering Note: The 6.5-meter limit applies to the combined carrier and extender arrangement. Do not interpret it as the permitted length of each individual cable.
Commissioning and Maintenance
The KJ4002X1-BF2 requires no calibration. It also contains no user-serviceable components.
- Verify the model and cable length before installation.
- Confirm the LocalBus power requirements against system documentation.
- Inspect connector seating after installation.
- Check cable routing and conduit protection.
- Isolate system power before removing the cable.
- Replace the complete cable if physical damage affects its integrity.
Do not disassemble the cable assembly. The manufacturer specifies no internal user maintenance or adjustment.
Compatibility and Selection Guide
The Emerson KJ4002X1-BF2 serves horizontal I/O carrier interconnection applications.
Before ordering, verify these engineering details:
- Carrier Type: Confirm that the existing carrier supports the required LocalBus extender connection.
- Connector: Verify the 44-pin interface.
- Cable Length: Confirm that 1.2 meters suits the cabinet layout.
- Power Requirements: Check the 12.6 VDC, 15 A LocalBus circuit specification.
- System Configuration: Calculate the total carrier and extender length.
- Installation Environment: Check temperature, humidity, vibration, and contamination conditions.
Important: Similar cable appearance does not confirm electrical or mechanical compatibility. Always compare the exact part number with the system bill of materials and Emerson installation documentation.

Frequently Asked Questions (FAQ)
Q1: What is the primary function of the Emerson KJ4002X1-BF2?
It connects compatible horizontal I/O carriers through the LocalBus interface. It supports the required LocalBus power and interconnection arrangement.
Q2: What are the cable length and connector specifications?
The cable measures 1.2 meters and uses a 44-pin connector configuration. Verify both details against the existing carrier assembly.
Q3: Can the total LocalBus connection exceed 6.5 meters?
No. The combined I/O carrier and LocalBus extender arrangement must not exceed 6.5 meters. Calculate the complete connection length before installation.
Q4: Can engineers disconnect the cable while the system remains energized?
No. De-energize the system before disconnecting carriers or extender cables. An exception applies only when the area is confirmed safe under the specified safety requirements.
Q5: Does the KJ4002X1-BF2 require regular calibration?
No. Calibration is unnecessary. The cable also contains no user-serviceable parts.
Q6: What should engineers check when a LocalBus connection fails?
First, isolate power and inspect the connector seating and cable condition. Then verify the cable part number, carrier compatibility, and total connection length. Check the system diagnostics before replacing other LocalBus components.
Q7: Can a different 44-pin extender cable replace this model?
Not automatically. Matching pin counts do not guarantee identical wiring or electrical characteristics. Compare the complete part number and Emerson compatibility documentation before substitution.
Q8: What information should buyers provide when requesting a replacement?
Provide the following details:
- Exact part number: KJ4002X1-BF2.
- Existing horizontal carrier model.
- Required cable length.
- System configuration and installation environment.
- Required quantity and delivery destination.
These details help suppliers verify the correct cable configuration and reduce ordering errors.
