ABB NKTU11-17 I/O Module to Termination Unit Cable

Basic Introduction

The ABB NKTU11 - 17 I/O Module to Termination Unit Cable is a cable used to connect an I/O module to a termination unit. In ABB's industrial automation systems, this cable plays a vital role in ensuring that signals are transmitted accurately and reliably between different equipment units.

Technical data

Length specifications: These cables are usually available in a variety of lengths to suit different installation layouts. Common lengths may include standard lengths such as 1 metre, 2 metres, 5 metres, etc. and can also be customised to suit specific project requirements.

Number of cores and specifications: It contains multiple cores, the exact number and specifications depend on the interface requirements of the connected I/O modules and terminal units. The cores are generally made of high-quality copper conductors to ensure good electrical conductivity. The cross-sectional area of the cores also varies depending on the current carrying capacity and other factors, and may be available in sizes of 0.5 mm², 0.75 mm², 1.0 mm², for example.

Insulation: The insulation of cables is usually a material with good insulating properties and chemical resistance, such as polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE). These materials are effective in preventing short circuits between cores and are resistant to chemical attack in industrial environments.

Shielding properties: In order to prevent external electromagnetic interference from affecting signal transmission, cables may have a shield. The shielding layer may be in the form of woven metal mesh or aluminium foil, etc. It can effectively shield the external electromagnetic interference and also reduce the outward radiation of signals inside the cable, improving the quality and confidentiality of signal transmission.

Functional characteristics

Signal transmission accuracy: Its main function is to transmit digital and analogue signals accurately. In industrial automation systems, various types of signals need to be transmitted between I/O modules and terminal units, including analogue signals collected by sensors (e.g. temperature, pressure, flow, etc.) and digital signals from control devices (e.g. start/stop signals of devices). This cable ensures the accuracy of these signals during transmission and reduces signal attenuation and distortion.

HIGH RELIABILITY: Thanks to the use of high-quality materials and strict manufacturing processes, this cable has a high degree of reliability. It can operate stably for a long time in harsh industrial environments and can withstand a certain degree of mechanical stress, temperature changes and chemical corrosion, thus ensuring the continuous and stable operation of industrial automation systems.

Good compatibility: Designed for good compatibility with ABB's NKTU11 - 17 I/O modules and corresponding terminal units. This compatibility makes the installation and connection process easier, reduces problems that may arise due to incompatible equipment, and improves the efficiency of system integration.

Application Scenarios

Industrial automated production lines: In automated production lines, the cable is used to connect various I/O modules, such as digital I/O modules for collecting device status and analogue I/O modules for monitoring production process parameters, to terminal units. For example, in an automotive manufacturing line, it connects the I/O modules of the robot control system to the terminal units of sensors and actuators on the robot arm, enabling precise control and status monitoring of the robot's movements.

Process control system: In the process control field of chemical industry, petrochemical industry and electric power, it is used to connect the I/O modules in the process control system with the terminal units of field devices. For example, in the chemical production process, it can be used to monitor the reactor temperature, pressure, liquid level of the I/O module and installed in the reactor temperature sensors, pressure sensors, liquid level sensors terminal unit connected to ensure that the production process of real-time monitoring and accurate control.

Intelligent Building Automation System: It is also widely used in the automation system of intelligent buildings. It can connect the I/O module in the building control system with the terminal units of the lighting system, air-conditioning system, lift system and other equipments to achieve centralised control and automated management of various equipments in the building, such as automatically adjusting the brightness of the lighting according to the indoor light intensity and personnel activities, and automatically adjusting the operation status of the air-conditioner according to the indoor temperature.
