Specifications

Description

The ABB NKTU01-10 is a Bailey Infi 90 Termination Unit Cable designed for the Bailey Infi 90 and Network 90 Distributed Control Systems (DCS). This cable serves as the vital link between control processor modules and their corresponding termination units, facilitating the transmission of process I/O and communication signals. The "-10" designation indicates a specific 10-foot length, providing sufficient reach for routing through standard industrial enclosures. Engineered to maintain signal integrity in electrically noisy environments, this cable is essential for ensuring reliable data flow between the system backplane and the field wiring interface.

Applications

Power plants: Used for boiler, turbine, and auxiliary system control in thermal, hydroelectric, or nuclear power plants.

Petrochemical plants: Safety signal connections between various sensors and controllers in oil refineries and chemical production lines.

Paper and pulp mills: Used for paper machine control and process automation.

Metallurgical and mining plants: Blast furnace control in steel plants and automated monitoring systems in mines.

Features

High-Integrity Data Path: Constructed with precision-aligned conductors to minimize signal attenuation and crosstalk during high-speed data transfers.

Flexible Routing: Designed with a bend radius suitable for tight cabinet configurations, allowing for organized cable management within Module Mounting Units (MMU).

Secure Interfacing: Equipped with heavy-duty connectors that ensure a vibration-resistant physical connection, critical for continuous operation in power plants and refineries.

EMI/RFI Resistance: Features internal geometry optimized to reduce the impact of electromagnetic interference commonly found in industrial control rooms.

Plug-and-Play Compatibility: Factory-terminated and tested to meet original equipment manufacturer standards for immediate integration into existing Infi 90 architectures.

FAQ

Q: Are NKTU01-10 and NKTU01-20 interchangeable?
A: Yes. Both have identical electrical definitions; the only difference is the length (10 feet vs. 20 feet). The longer cable can replace the shorter one, provided there is sufficient space in the cabinet.

Q: Can this NKTU01-10 be used in hazardous locations?
A: Yes. According to the official manual, this series of cables meets UL Listed PLTC certification and is suitable for Class I Division 2 hazardous locations.

Q: Is system shutdown required when replacing NKTU01-10?
A: System shutdown is recommended. Although plugging and unplugging the cable itself does not involve a large current, disconnecting the I/O and terminal unit connections will open the relevant control circuit, potentially triggering system interlock protection.

Q: Why has the outer sheath of my NKTU01-10 cable become so hard?
A: Prolonged exposure to high temperatures (above a certain temperature) or chemical corrosion can cause the PVC material to age and become brittle. In this case, it should be replaced promptly to prevent short circuits.

Q: Is this NKTU01-10 specifically designed for analog or digital signals?
A: It's a universal cable. It's designed for Harmony Rack I/O modules and can transmit 4-20mA analog signals or 24VDC/125VDC digital signals.
