Question 1: What is the purpose of the ABB NKTU01-12 Termination Loop Cable?

The ABB NKTU01-12 Termination Loop Cable is used in INFI-Net communication networks to provide a termination loop for coaxial cables, ensuring proper signal continuity and stable communication across devices in an industrial system. This cable is essential for completing the loop in the network and preventing signal reflections, which can cause data transmission errors or loss of communication. 

Question 2: What are the key features of the ABB NKTU01-12 Termination Loop Cable?

Signal Continuity: The NKTU01-12 ensures proper signal continuity in INFI-Net communication systems by completing the required loop, which prevents signal degradation and ensures stable data transmission.

Low Loss and High Integrity: The NKTU01-12 cable minimizes signal loss, ensuring high-quality communication even over extended distances or in environments with potential electromagnetic interference (EMI).

Question 3: How do I install and troubleshoot the ABB NKTU01-12 Termination Loop Cable?

Locate the Network Termination Points: Identify the termination points where the loop cable will be installed. These are typically at the ends of the communication line or between network devices that need the loopback connection.

Connect the Cable: Attach the NKTU01-12 Termination Loop Cable to the designated ports on the devices or network components. 

Secure the Cable: Ensure that the cable is securely fastened and that the connectors are properly seated to avoid signal interruptions.

It is used primarily in signal transmission loops to ensure accurate and reliable communication between devices, such as transmitters, controllers, and monitoring systems. 

This cable is essential for proper system operation, offering both durability and electrical performance in demanding industrial environments.

The NKTU01-12 cable is typically rated for 300V to 600V operation, depending on the specific requirements of the connected equipment and system configuration.

The use of tinned copper in the cable provides high conductivity, excellent resistance to corrosion, and reliable performance over time. Copper conductors ensure efficient and low-resistance signal transmission, crucial for precise control and monitoring.

Foil Shielding or Braided Shielding: The NKTU01-12 cable is often equipped with shielding to reduce electromagnetic interference (EMI) and radio frequency interference (RFI).

The NKTU01-12 cable typically operates within a temperature range of -20°C to +80°C (-4°F to +176°F), making it suitable for most industrial environments.

The resistance of the conductor is typically low, around 0.02 Ω/m, depending on the conductor gauge and length. This low resistance ensures minimal signal loss over long cable runs.

Insulation Resistance: The insulation resistance is typically higher than 100 MΩ/km, ensuring proper electrical isolation between conductors and preventing leakage or short-circuits.

The cable may be designed with 50Ω or 75Ω impedance to ensure compatibility with specific loop and signal transmission applications. 

The typical outer diameter of the NKTU01-12 cable is between 5 mm to 10 mm, depending on the construction, number of conductors, and insulation materials.
