NKTU01-11 ABB Bailey Termination Unit Cable (PVC)

NKTU01-11 Termination Unit Cable is a dedicated cable component used in ABB's automation control systems to connect I/O modules with the termination unit (Termination Unit, TU). This product comes in a standard length of 11 feet and is suitable for signal connections between internal modules in the control cabinet and the termination unit, helping to achieve a clear, standardized, and reliable system wiring structure. It is commonly used in ABB Symphony, Harmon,y and INFI 90 control systems.

The ABB NKTU01-11 termination unit cable is a robust industrial-grade cable designed to connect I/O modules to termination units in ABB Bailey INFI 90 distributed control systems (DCS). Engineered for reliable low-voltage signal transmission in process automation, this 11-foot (≈3.35 m) PVC-insulated cable ensures stable communication and excellent durability in demanding industrial environments. With optimized conductivity and shielding, it supports efficient signal integrity and minimizes electromagnetic interference, making it ideal for power plants, manufacturing, water treatment, and other automation applications.

Specialized cable design for termination units
As a Termination Unit Cable, NKTU01-11 Termination Unit Cable is used to establish a stable physical connection between the I/O module and the termination unit, ensuring a clear and controllable signal path.
Standardized length configuration (11 ft)
Suitable for cabinet layouts where the terminal unit and I/O module are relatively close to each other, it helps reduce excess cables and improve wiring tidiness.
Prefabricated termination structure
The NKTU01-11 Termination Unit Cable has undergone termination processing upon leaving the factory, eliminating the need for secondary wiring on site, thereby reducing the complexity of the construction.
Suitable for the industrial environment inside the control cabinet
The structural design meets the general requirements for industrial control cabinets, facilitating installation, wiring organization, and maintenance.
Compatible with multiple series of ABB termination units
It can be used in conjunction with various ABB Termination Units, facilitating unified planning of the system.

1 . Standard connection between the I/O module and the stop unit
As a dedicated connection cable for the I/O module to the stop unit in the control system, it builds a stable signal channel. 
2.Standardized application of wiring inside the control cabinet
By using the standard Termination Unit Cable, the wiring inside the cabinet becomes clearer, facilitating later inspection and maintenance. 
3.New DCS / Control System Project
In the initial stage of the system, the use of terminal unit cables is uniformly adopted, which helps to enhance the overall consistency of the project.
4.System expansion and local renovation
When adding or adjusting the position of the termination unit, an appropriate length of cable can be selected for quick connection.
5.Maintenance of spare parts and on-site replacement
As the connection cable for the commonly used terminal unit, it is suitable to be included in the maintenance spare parts system.

Q1: What is the main function of the NKTU01-11 Termination Unit Cable in the system?
A: As a Termination Unit Cable, it is used to connect the I/O module with the termination unit, and complete the signal transmission from the module to the terminal.
Q2: How is this product different from ordinary control cables?
A: NKTU01-11 is a dedicated cable for the final stage unit. Its interface and structure are compatible with the ABB final stage unit, making it more suitable for long-term stable operation.
Q3: What wiring scenarios are suitable for an 11 ft length?
A: Itappliese to applications where the distance between the I/O module and the termination unit is short, and the control cabinet layout is compact.
Q4: Can it be used in conjunction with different types of termination units?
A: Within the ABB control system architecture, it can be used in combination with various compatible Termination Units.
Q5: Is the termination unit cable easy to maintain and replace?
A: The standardized model and length configuration facilitate quick identification and replacement at the site.

ABB Bailey Infi 90

 

ABB Bailey Infi 90 is a classic distributed control system (DCS) widely used in industrial automation with high reliability and advanced control functions.

 

1987

 

The Infi 90 was originally launched in 1987.

 

1992

 

This was later developed into the INFI 90 Open in 1992. This was followed in 1996 by the launch of Symphony Harmony.
