Product Description
The ANB11D-B25 is a high-performance modular I/O interface designed to extend the reach of Yokogawa CENTUM VP control systems. As an Optical ESB Bus Node Unit, it enables high-speed, deterministic data acquisition by connecting remote field instruments to the central Field Control Unit (FCU) via fiber optic communication.
By leveraging optical transmission, the ANB11D-B25 eliminates distance limitations and minimizes electromagnetic interference, making it ideal for large-scale and geographically distributed industrial systems.
This unit features a dual-redundant 220–240 V AC power supply architecture, ensuring continuous operation and high system availability. It also serves as a robust housing platform for up to eight I/O modules, providing both communication backplane functionality and power distribution for analog and digital signal processing.

Deployment Scenarios
The ANB11D-B25 is widely used in industries such as oil & gas, chemical processing, and power generation. It is particularly effective in applications like tank farms, offshore platforms, and large industrial campuses where field devices are located far from the main control system.
By utilizing fiber optic communication, this unit ensures stable, long-distance signal transmission without degradation, eliminating the need for additional signal boosters and reducing grounding or noise-related issues.
Technical FAQ
Q: What makes the B25 suffix unique compared to other ANB11D models?
A: The B25 suffix indicates a 220–240 V AC power supply configuration and classifies the unit as a basic type for general-purpose industrial environments.
Q: Can this unit be installed in a standard server rack?
A: Yes. It complies with the EIA/JIS 19-inch rack standard, but requires 8U vertical space and adequate airflow for proper cooling.
