Product Overview

The ABB Bailey NKCL01-30 is an INFI 90 COAX INFI-Net Cable used for physical network interconnection within ABB Bailey INFI 90 control systems. It provides the coaxial communication path required to connect INFI-Net network points and associated system hardware.

In an operating INFI 90 system, the cable forms part of the communication layer between controllers, network interfaces, and other INFI-Net components. Its 30-foot length is suited to installations where the connected equipment is distributed across a control cabinet, equipment rack, or adjacent control-system sections.

Because it is a passive interconnection component, the NKCL01-30 does not perform signal processing or control logic. Its function is to maintain the physical communication path between compatible INFI-Net devices.

Technical Specifications

Product Features

• Supports physical communication interconnection in ABB Bailey INFI 90 systems.
• Uses a coaxial cable construction for the INFI-Net communication path.
• Suitable for connecting compatible INFI-Net network components and system hardware.
• Functions as a passive communication-layer component without independent processing.
• Useful for cabinet, rack, and control-system interconnection where the required cable route is longer than shorter NKCL01 variants.
• Can be applied as part of existing INFI 90 system maintenance, replacement, or expansion work.

Working Principle

The NKCL01-30 operates as the physical transmission path for the INFI-Net network. When connected between compatible INFI-Net interfaces, the coaxial cable carries the communication signals between the connected system components.

The cable itself does not interpret messages or execute control functions. Network communication is handled by the connected INFI 90 hardware, while the NKCL01-30 maintains the electrical connection between those interfaces.

In practical maintenance work, the cable should be treated as part of the communication infrastructure. A damaged connector, poor connection, or incorrect cable routing can interrupt communication even when the connected controllers and network hardware are operating normally.

Role in an INFI 90 Control Architecture

The NKCL01-30 occupies the physical interconnection layer of an INFI 90 control architecture. It links compatible INFI-Net interfaces so that network communication can pass between the connected control-system components.

Industrial Applications

Installation and Maintenance

1. Verify the cable application — Confirm that the NKCL01-30 is intended for the specific INFI-Net connection before installation.
2. Check the mating interfaces — Inspect the connectors and connected network interfaces for compatibility and physical condition.
3. Inspect the cable before installation — Look for cuts, crushed sections, damaged insulation, or other visible defects.
4. Route the cable carefully — Avoid sharp bends, excessive mechanical stress, and locations where the cable can be pinched.
5. Keep communication cabling organized — Maintain clear routing inside cabinets and equipment areas to simplify future troubleshooting.
6. Secure the cable appropriately — Prevent unnecessary movement or strain on the cable and its connection points.
7. Avoid unnecessary cable modification — Do not alter the cable construction unless the applicable ABB Bailey installation procedure specifically permits it.
8. Check both connection points — Make sure each end is fully seated and mechanically secure.
9. Inspect for communication faults — After installation, verify that the connected INFI-Net devices communicate normally.
10. Check connections during troubleshooting — When a network node becomes unavailable, inspect the cable and its interfaces before replacing active network hardware.
11. Replace damaged cables — A cable showing physical damage or persistent communication problems should be removed from service and replaced with a suitable component.
12. Document cable routing — Record the installed connection path so future maintenance personnel can identify and service the network connection efficiently.

Technical FAQs

What is the function of the ABB Bailey NKCL01-30?

The NKCL01-30 provides the physical coaxial communication path for compatible INFI-Net connections within ABB Bailey INFI 90 systems. It connects network interfaces without performing independent signal processing or control functions.

Is the NKCL01-30 an analog I/O termination cable?

No. The NKCL01-30 is an INFI-Net communication cable. It should be distinguished from ABB Bailey NKAS01-series analog module termination cables, which serve a different interconnection function.

Where is the NKCL01-30 typically used?

It can be used between compatible INFI-Net interfaces in INFI 90 control installations, including control cabinets, equipment racks, and distributed sections of an industrial control system.

What should be checked if an INFI-Net connection becomes intermittent?

Inspect the cable routing, connectors, connection points, and visible cable condition first. If the physical connection is intact, troubleshooting can then continue toward the associated INFI-Net interface and other network components.
