Product Overview

The ABB Bailey NKTL01-3 is an Infi 90 Coax Termination Cable used within ABB Bailey Infi 90 control system installations for coaxial signal and network connections. It belongs to the physical interconnection layer of the system, where properly terminated coaxial connections are required to maintain communication between control-system components.

In an Infi 90 installation, coaxial cabling can be routed between system modules, termination points, and associated network hardware. The NKTL01-3 provides a defined cable connection for installations where a 3-foot coaxial termination cable is required.

This type of cable is particularly useful during system expansion, cabinet wiring, replacement work, or maintenance of an existing Infi 90 installation. Correct cable identification is important because a visually similar coaxial cable may have different termination arrangements or be intended for another section of the control architecture.

Technical Specifications

Product Features

• Infi 90 system compatibility — Intended for use within ABB Bailey Infi 90 control-system applications.
• Coaxial connection — Provides a dedicated coaxial cable connection between compatible system points.
• 3-foot cable length — Suitable for short-distance cabinet and equipment interconnections.
• Termination cable construction — Supports organized connection between designated Infi 90 system components.
• Useful for maintenance — Appropriate for replacement of an identified cable during service work.
• Cabinet-friendly installation — The relatively short cable length can help keep local control-system wiring organized.

Working Principle

The NKTL01-3 functions as a physical transmission path within the Infi 90 system. It does not perform signal processing or control logic itself; its purpose is to establish the required coaxial connection between compatible system components.

A simplified connection can be represented as:

Infi 90 System Component → NKTL01-3 Coax Termination Cable → Infi 90 System Component

When installed in the correct position, the cable maintains the electrical connection required for the associated coaxial communication or signal path.

For maintenance work, the cable should be considered part of the complete communication path. If an Infi 90 node or associated system section reports a communication problem, technicians should inspect the cable condition and termination points along with the connected hardware. A loose connector, damaged cable, or incorrect replacement can interrupt an otherwise functional control-system network.

Role in an Infi 90 Control System

The NKTL01-3 therefore belongs to the physical infrastructure rather than the processing layer. Its condition can directly affect the continuity of the associated coaxial connection.

Industrial Applications

Installation and Maintenance

1. Confirm the cable identification — Verify that NKTL01-3 is the required cable for the intended Infi 90 connection before installation.
2. Check the connection points — Inspect both mating interfaces for contamination, physical damage, loose hardware, or signs of deterioration.
3. Route the cable correctly — Keep the coaxial cable properly routed and avoid unnecessary mechanical stress, sharp bends, or contact with moving components.
4. Secure the termination — Make sure the cable is fully seated and the termination is mechanically secure before returning the system to service.
5. Inspect replacement cables — Compare the replacement cable with the removed cable and confirm the part number and cable length before installation.
6. Check communication after installation — Following replacement, verify the status of the associated Infi 90 system section and confirm that the expected communication path has been restored.
7. Maintain spare identification records — Store the part number together with the equipment location and application information to simplify future maintenance.

Technical FAQs

What is the primary function of the ABB Bailey NKTL01-3?

The NKTL01-3 is a coax termination cable intended for compatible ABB Bailey Infi 90 system connections. It provides the physical coaxial connection required between designated system points.

Does the NKTL01-3 perform any control or signal-processing function?

No. The cable itself does not execute control logic or process signals. Its function is to provide the electrical connection between compatible Infi 90 components or termination points.

Why should the exact cable part number be checked before replacement?

Infi 90 installations can contain multiple cables with similar physical appearances but different lengths, termination arrangements, or intended connection points. Confirming NKTL01-3 before replacement helps prevent an incorrect cable from being installed in the system.

What should be inspected if an Infi 90 communication path becomes unstable after cable replacement?

Check that the NKTL01-3 is installed at the correct connection points and that both terminations are properly seated. The cable should also be inspected for physical damage or excessive mechanical stress. If the cable installation is correct, the connected communication hardware and the wider system path should then be checked.
