ABB NKTU11-20 I/O Module to Termination Unit Cable

ABB NKTU11-20 I/O Module to Termination Unit Cable

Technical Parameters

Electrical parameters:

Rated voltage: usually 24V DC or 110V AC/220V AC, etc., to meet the power supply requirements of different I/O modules and terminal units.

Rated current: generally within a few amperes to meet the signal transmission and power supply requirements of conventional equipment.

Signal transmission rate: supports high data transmission rate, which can meet the rapid transmission of digital and analogue signals to ensure the real-time and accuracy of the system.

Mechanical parameters:

Length: Its standard length is generally 20 feet, in the actual application can also be customised according to the specific installation distance and needs.

Diameter: Generally between a few millimetres and a dozen millimetres, depending on factors such as the number of cores inside the cable, the thickness of the insulation and the structure of the shield.

Plug and socket specifications: Plugs and sockets are of a specialised design matched to ABB's specific I/O modules and terminal units, ensuring robust connections and reliable signal transmission.

Environmental parameters:

Operating temperature range: Typically capable of normal operation over a wide temperature range from - 20°C to around + 70°C, with some special models available for more extreme temperatures.

Humidity range: the relative humidity range is generally 5% to 95% (non-condensing), can be stable in the humid industrial environment.

Protection level: With a certain protection level, such as IP40 or higher, it can prevent solid objects with a diameter of more than 1mm from entering, and is waterproof and dustproof to a certain extent, protecting the internal core and signal transmission from the influence of the external environment.

Functionality

Signal transmission function: It can transmit various types of signals, including digital and analogue signals. In the transmission process, shielding design is adopted to reduce the impact of electromagnetic interference on the signals and ensure the accuracy and stability of the signals, which can reliably transmit the signals even in the complex industrial electromagnetic environment.

Connection compatibility: The cable's plugs and sockets are designed to match perfectly with ABB's I/O modules and terminal unit interfaces, ensuring a tight and reliable connection. At the same time, it supports system expansion and updating, and can be easily reconfigured and reconnected when I/O modules or terminal units need to be added or replaced.

Application Areas

Industrial automation production line: Widely used in various industrial automation production lines such as automobile manufacturing, electronic product manufacturing, food and beverage production, etc. It connects the I/O modules and terminal units of the production equipments to realise the signal transmission and control between the equipments.

Process control system: In chemical, petroleum, electric power and other process industries, it is used to connect the I/O modules and terminal units of various process control equipment, such as sensors, transmitters, actuators, etc., to achieve precise control and monitoring of the production process.

Intelligent Building Automation System: In the HVAC system, lighting system, security system, etc. of intelligent buildings, I/O modules and terminal units are connected to realise intelligent control and management of building equipment, and to improve the building's energy efficiency and comfort.
