ABB NKTU01-3 I/O Module to Termination Unit Cable

ABB NKTU01-3 I/O Module to Termination Unit Cable

Basic Characteristics

Length specification: Commonly, there are standard lengths such as 1 metre, 2 metres, 3 metres, etc., and special lengths can also be customised according to specific needs.

Appearance and marking: Usually the cable jacket is black or grey, with clear marking of model, specification and brand printed on it, which is easy to identify and install and maintain.

Technical Performance

Electrical performance:

Rated voltage: generally about 300V, which can meet the common voltage requirements in industrial sites and ensure stable signal transmission within the normal working voltage range.

Signal transmission rate: with high transmission rate, it can quickly and accurately transmit digital and analogue signals between I/O modules and terminal units to meet the real-time requirements of industrial automation systems.

Signal attenuation: within the specified transmission distance, the signal attenuation rate is low, which can ensure the integrity of the signal during long-distance transmission and reduce the problems of signal distortion or BER caused by signal attenuation.

Mechanical properties:

Wear-resistant: the cable jacket is made of wear-resistant materials, such as polyvinyl chloride (PVC) or polyurethane, etc., which can resist mechanical abrasion in long-term use and extend the service life of the cable.

Anti-tensile: with a certain degree of tensile strength, it can withstand a certain degree of external tension without being easily damaged, ensuring the stability of the connection in the process of installation and use.

Flexibility: the cable is soft and easy to bend, convenient for wiring and connection in different installation environments, and can be adapted to a variety of complex industrial site layout.

Functions and Roles

Signal transmission: The main function is to transmit signals accurately and stably between NKTU01-3 I/O modules and terminal units, including digital input/output signals, analogue input/output signals, etc., so as to realize the information interaction between field equipment and control system.

System Integration: As an important part of Pöyry Infi 90 system, the cable ensures the reliable connection between I/O modules and terminal units, which contributes to the integration and stable operation of the whole system, and improves the system's automation control level and production efficiency.

Areas of application

Power industry: In power plants, substations and other places, it is used to connect the I/O modules and terminal units of various automation and control equipment, such as the monitoring system of generator sets and the automation and protection system of substations, etc., to realise the remote monitoring and automation control of power equipment.

Chemical industry: In the process of chemical production, I/O modules of various sensors and actuators can be connected with terminal units of control systems, such as temperature sensors, pressure sensors, regulating valves, etc., to achieve precise control and safety monitoring of chemical production processes.

Metallurgical industry: In the automated production line of iron and steel, non-ferrous metal and other metallurgical enterprises, it is used to connect the I/O modules and terminal units of the production equipment, such as the control system of rolling mills, continuous casting machines, electric furnaces and other equipment, to ensure the efficient and stable operation of the production process.
