ABB NKEB02 Expander Bus Interconnect Cable

ABB NKEB02 Expander Bus Interconnect Cable

Basic Information

Appearance and size: It is usually a black or gray round cable with moderate wire diameter and flexibility for easy installation and wiring. Its length specifications are varied, common 1 m, 2 m, 5 m and other standard lengths, can also be customized according to customer demand for special lengths.

Place of origin: generally from the United States and other industrially developed countries.

Technical Parameters

Electrical Performance

Rated voltage: generally between 24V DC and 48V DC, which can provide stable power supply for the expansion bus module to ensure the normal operation of the module.

Rated current: according to specific application scenarios and load requirements, the rated current is usually between 1A and 3A, which can meet the power requirements of multiple expansion modules.

Signal transmission rate: supports high data transmission rate, usually up to several Mbps, which can quickly and accurately transmit control signals and data information between expansion modules.

Transmission Characteristics

Signal type: mainly transmits digital signals, including equipment control instructions, status feedback signals, parameter setting signals, etc., to realize efficient communication between the expansion module and the main system.

Transmission distance: under the premise of guaranteeing the signal quality, the transmission distance can generally be up to several dozens of meters, the specific transmission distance depends on the quality of the cable, the type and strength of the transmission signal and the electromagnetic interference of the surrounding environment.

Functional characteristics

Connecting expansion modules: As an expansion bus interconnection cable, its main function is to connect the expansion modules in ABB Bailey Infi 90 system, such as I/O expansion modules, communication expansion modules, special function expansion modules, etc., to realize the flexible expansion and function customization of the system.

High-speed and stable communication: adopting high-quality conductor and shielding materials to ensure high-speed and stable signal transmission, reduce signal attenuation and distortion, ensure reliable communication between the expansion module and the main system, and improve the overall performance of the system.

Strong anti-interference ability: with good shielding performance, it can effectively resist external electromagnetic interference, such as electromagnetic interference generated by motors, frequency converters and other equipment at industrial sites, and at the same time, it can also prevent internal signals from radiating outward, avoiding interference with other equipment, and ensuring the stable operation of the system in a complex electromagnetic environment.

Easy to install and maintain: Adopting standardized interfaces and connections, such as plug-and-play connections, the installation is simple and convenient without special tools, and it also facilitates the maintenance and expansion of the system, which reduces the installation and maintenance costs of the system.

Application Fields

Industrial automation control system: Widely used in automation control system of electric power, chemical industry, steel, paper making and other industrial fields, used to connect various expansion modules to realize real-time monitoring and precise control of production process, such as distributed I/O control, remote communication, intelligent meter connection, etc.

Intelligent building system: In the security system, lighting system and air conditioning system of intelligent building, it can be used to connect the expansion module to realize the function expansion and intelligent management of the system, such as increasing the monitoring point, expanding the lighting control area, realizing the remote monitoring of the air conditioning system and so on.

Transportation system: In signal system, monitoring system, ticketing system and so on in the field of transportation such as railroad, subway, airport, etc., it is used to connect the relevant expansion module to ensure the normal operation and safety of the system, such as increasing signal monitoring points, expanding monitoring range, realizing the function upgrade of ticketing system and so on.
