Product Overview
The ABB Bailey NKTM02-15 is an Infi 90 Expansion Cable used to establish physical interconnections between compatible components within an ABB Bailey Infi 90 control system. With a 15-foot cable length, it can be used where system components are positioned farther apart than a shorter expansion cable can accommodate.
In a typical Infi 90 control cabinet, system hardware may be distributed across different mounting sections or cabinet areas. The NKTM02-15 provides the cable path needed to connect applicable system components while allowing more flexibility in equipment placement and cable routing.
It is also useful as a maintenance replacement for existing Infi 90 installations. When an expansion cable has been damaged, aged, or removed during cabinet work, the correct replacement cable helps restore the original system interconnection without changing the active control hardware.

Product Features
- Infi 90 system application — Intended for compatible ABB Bailey Infi 90 system interconnections.
- 15-foot cable length — Provides additional installation reach for system components positioned farther apart.
- Expansion connection — Used to establish the required physical connection between applicable Infi 90 components.
- Cabinet installation flexibility — The longer cable length can simplify routing between separate cabinet sections or mounting locations.
- Maintenance replacement — Suitable for replacing an existing expansion cable during troubleshooting or control-system maintenance.
- Legacy system support — Helps maintain existing Infi 90 installations without requiring replacement of the associated control hardware.
Working Principle
The NKTM02-15 functions as a passive physical connection within the Infi 90 system. Unlike an electronic control module, it does not execute control logic, process field signals, or make control decisions.
The basic connection path can be represented as:
Infi 90 Component → NKTM02-15 → Infi 90 Component
The cable maintains the required connection between compatible system elements. Its 15-foot length gives the installer additional routing distance, which can be useful when the connected components are located in different cabinet areas.
During troubleshooting, the cable should therefore be checked as part of the physical interconnection path. Connector seating, cable condition, routing, and correct part-number selection are important points to verify if the connected system section does not operate as expected.
Role in an Infi 90 Control System
| System Element | Function |
|---|---|
| Infi 90 Controller | Executes control functions and system processing |
| Infi 90 I/O Hardware | Interfaces process signals with the control system |
| NKTM02-15 | Provides the required physical expansion connection |
| Infi 90 Communication Hardware | Supports communication between applicable system sections |
| Cabinet Wiring | Provides the supporting electrical interconnection infrastructure |
Industrial Applications
| Application | Typical Use |
|---|---|
| Process Control Cabinets | Connecting Infi 90 components installed in different cabinet locations |
| Power Generation | Maintaining expansion connections in legacy plant control systems |
| Oil and Gas | Supporting existing Infi 90 control-system interconnections |
| Chemical Processing | Connecting distributed control hardware within process-control cabinets |
| Water Treatment | Maintaining physical connections between Infi 90 system sections |
| Control System Maintenance | Replacing damaged or aged expansion cables during service work |
Installation and Maintenance
- Verify the part number — Confirm that NKTM02-15 is the correct expansion cable for the intended Infi 90 connection before installation.
- Inspect the cable — Check the cable and connection ends for visible damage, contamination, deformation, or other conditions that could affect installation.
- Identify both connection points — Confirm that each end is connected to the correct compatible Infi 90 system component.
- Route the cable carefully — Use the available 15-foot length to establish a suitable routing path without placing unnecessary mechanical stress on the cable.
- Check connector seating — Make sure the connections are fully seated before returning the system to normal operation.
- Verify system operation — After replacement or installation, check the affected Infi 90 section and confirm that the expected system functions are restored.

Technical FAQs
What is the main purpose of the NKTM02-15 in an Infi 90 system?
The NKTM02-15 is used to establish the required physical expansion connection between compatible ABB Bailey Infi 90 system components. Its 15-foot length makes it suitable for installations where the connected components require a longer cable path.
When would the NKTM02-15 be preferred over a shorter Infi 90 expansion cable?
The NKTM02-15 can be considered when the distance between the applicable connection points requires additional cable length. It can be particularly useful when Infi 90 hardware is distributed across different cabinet sections or mounting locations.
Does the NKTM02-15 perform any control or signal-processing function?
No. The NKTM02-15 is a passive expansion cable. It does not execute control logic or process signals; its function is to maintain the physical connection between compatible Infi 90 system components.
What should be inspected when replacing an NKTM02-15 during Infi 90 maintenance?
Check the cable condition, connection points, connector seating, and routing before returning the system to operation. It is also important to verify that the replacement cable is the correct part number and that the connected Infi 90 components match the intended application.
