ABB NKAS11-45 Analog Slave Termination Unit Cable

ABB NKAS11-45 Analog Slave Termination Unit Cable

Basic Structure

Conductor: Usually high purity copper to ensure good electrical conductivity and signal transmission quality, lower resistance and reduce signal attenuation during transmission.

Insulation layer: generally high-quality insulating materials, such as polyvinyl chloride (PVC), cross-linked polyethylene (XLPE) or polytetrafluoroethylene (PTFE), etc., with good insulation properties, voltage resistance and low-loss characteristics, which can effectively prevent short-circuiting between the conductors and signal leakage.

Shield: mostly copper tape or braided copper mesh structure, can provide good electromagnetic shielding effect, effectively prevent the external electromagnetic interference on the internal signal, but also to avoid internal signal radiation to the outside, to ensure the stability and reliability of signal transmission.

Sheath: usually made of low-smoke halogen-free material or flame retardant PVC material, which has good resistance to abrasion, corrosion, weather aging and flame retardant properties, and can protect the internal structure of the cable in harsh industrial environments and improve the service life and safety of the cable.

Technical Parameters

Rated voltage: generally about 24V DC, which can provide stable working voltage for analog slave terminal unit to ensure its normal operation and signal transmission.

Rated current: According to the connected equipment and load, the rated current is usually between 0.5A and 1.5A, which can meet the power demand of multiple analog slave terminal units.

Characteristic impedance: commonly 50Ω or 75Ω, matching the impedance of other devices and networks in the system to achieve efficient signal transmission and reduce signal reflection and attenuation.

Signal Transmission Rate: Supports high data transmission rates, typically up to several Mbps or higher, for fast and accurate transmission of analog signals and control commands.

Functional features

High compatibility: Specially designed for the analog slave terminal unit of ABB Bailey Infi 90 system, it has good compatibility with other devices in the system, such as PLC, DCS system, communication module, etc., which ensures the stable operation of the system and reliable communication between devices.

Strong anti-interference: Its good shielding structure and high-quality shielding materials make the cable have excellent anti-interference ability, which can effectively resist electromagnetic interference generated by industrial sites such as motors, frequency converters, high-voltage equipment, etc., and at the same time, prevent the internal signals from radiating outward, avoiding interference with other equipment.

Good stability: the use of high-quality materials and advanced manufacturing processes to ensure the stability of the cable's electrical and mechanical properties, signal transmission attenuation is small, able to transmit signals stably for long periods of time, reduce signal loss and BER, and improve the reliability of the system.

Convenient installation and maintenance: Usually adopts standardized interfaces and connections, such as BNC connector, RJ45 connector or other special connectors, the installation process is simple and convenient, without special tools, and it is also more convenient in the maintenance and expansion of the system, which can reduce the installation and maintenance costs of the system.
