YOKOGAWA ANB11D-B25BU2A

The YOKOGAWA ANB11D-B25BU2A is a robust dual-redundant ESB bus node unit integrated with an optical repeater, engineered exclusively for Yokogawa CENTUM VP AFV300 and AFV400 series distributed control systems. As a core field communication component for industrial process automation, this module solves long-distance bus signal transmission limitations, delivering stable, interference-free data connectivity for chemical, oil & gas, power plant, and heavy manufacturing industrial sites.

Built with industrial-grade optical transmission technology, the YOKOGAWA ANB11D-B25BU2A upgrades standard electrical ESB bus signals to optical fiber transmission, completely isolating electromagnetic interference and signal attenuation in long-distance wiring. It supports ultra-long transmission distances up to 50 km, far exceeding conventional bus modules, making it ideal for large-scale, widely distributed industrial control networks and remote field equipment monitoring.

Equipped with comprehensive professional technical parameters, the YOKOGAWA ANB11D-B25BU2A features flexible multi-power compatibility, supporting 100–120V AC, 220–240V AC, and 24V DC power inputs to adapt to diverse on-site power supply conditions. Adopting a dual-redundant power and bus structure, it eliminates single-point failure risks, ensuring uninterrupted system operation during equipment switching or partial circuit maintenance.

For harsh environment adaptability, the module complies with ISA G3 industrial standards, operating reliably within a wide temperature range of -20°C to 70°C and 10%–90% non-condensing humidity. Its reinforced industrial casing resists vibration, dust, and corrosive industrial atmospheres, extending service life in rigorous production environments. The optimized internal circuit design ensures low power consumption while maintaining 100% accurate bus data transmission and fast signal response.

The YOKOGAWA ANB11D-B25BU2A supports flexible network topology layout and seamless compatibility with all CENTUM VP system modules. It simplifies on-site network deployment, reduces system wiring costs, and lowers daily maintenance frequency. With high stability, strong scalability, and strict Yokogawa original manufacturing standards, it serves as a premium replacement and upgrade solution for industrial ESB bus communication systems.
