Product Overview

The ABB Bailey NTCF02 Infi 90 Fiber Optic Termination Unit is used as a fiber optic termination component in ABB Bailey Infi 90 control-system installations. It provides a defined connection point for fiber optic communication wiring associated with the control-system network.

In an Infi 90 control cabinet, the NTCF02 can be used where fiber optic communication links need to be organized between control-system equipment and remote system sections. The termination arrangement helps keep fiber connections identifiable and manageable during commissioning, troubleshooting, and maintenance.

In a large process plant, for example, fiber optic communication may be routed between separate control cabinets or distributed system areas. The NTCF02 can form part of this communication path, with the connected fiber link carrying control-system information between the associated Infi 90 equipment.

For replacement work, technicians should verify the complete NTCF02 model, existing fiber connections, cable routing, connector assignments, and associated Infi 90 communication hardware before disconnecting the installed unit.

Working Principle

The NTCF02 serves as the termination interface for the fiber optic communication path used by associated Infi 90 system equipment.

Infi 90 Communication Equipment → NTCF02 → Fiber Optic Cable → Remote Infi 90 Equipment

The associated communication hardware sends and receives system data through the optical communication path. The NTCF02 provides the physical termination point for the fiber connection, while the connected communication equipment handles the actual exchange of control-system information.

Fiber optic connections are particularly useful in installations where control cabinets are separated by distance or where electrical interference makes conventional communication wiring less suitable.

Typical information carried through the communication architecture may include:

• Control-system data
• Process information
• Equipment status
• System diagnostics
• Communication data between distributed control sections

The NTCF02 itself does not execute PLC or process-control logic. Its function is associated with the physical termination and organization of the fiber communication connection.

Role in an Infi 90 Control Architecture

The NTCF02 operates at the fiber optic communication interface layer of an ABB Bailey Infi 90 system.

Infi 90 Controller / Communication Hardware → NTCF02 → Fiber Optic Network → Remote Infi 90 System

Industrial Applications

Installation and Maintenance

1. Confirm the complete NTCF02 model before installation or replacement.
2. Identify the associated Infi 90 communication equipment.
3. Record the existing fiber connection arrangement before disconnecting the unit.
4. Label the fiber connections according to the system documentation.
5. Inspect fiber optic connectors for contamination or physical damage.
6. Check the fiber routing for excessive bending, tension, or mechanical stress.
7. Install the NTCF02 in the approved cabinet location.
8. Reconnect the fiber optic cables according to the documented connection arrangement.
9. Confirm that each connector is properly seated.
10. Check the communication path after restoring the system.
11. Review communication diagnostics if the remote equipment cannot be reached.
12. Record the final fiber connection arrangement for future maintenance.

When troubleshooting a communication fault, the NTCF02, fiber connectors, cable path, associated communication hardware, and remote Infi 90 equipment should be checked individually to determine where the communication path is interrupted.

Technical FAQs

What is the ABB Bailey NTCF02 used for?

The NTCF02 is an Infi 90 Fiber Optic Termination Unit used to terminate and organize fiber optic communication connections within the associated control-system architecture.

What should be checked before replacing an NTCF02?

The existing fiber connections, connector assignments, cable routing, associated communication equipment, and system documentation should be checked before disconnecting the unit.

Can the NTCF02 itself perform Infi 90 control functions?

No. The NTCF02 is a termination component. Control logic and communication processing are handled by the associated Infi 90 controllers and communication equipment.

How should a fiber communication fault involving the NTCF02 be investigated?

Start by checking the termination connections and fiber connectors, then inspect the fiber cable path and associated communication equipment. Communication diagnostics at the local and remote Infi 90 equipment can help determine whether the problem is located at the termination, cable, or system level.
