Yokogawa ANB10D-425/CU2N ESB Bus Node Unit
ANB10D-425/CU2N
The Yokogawa ANB10D-425/CU2N is a dual-redundant ESB bus node unit designed to interface field I/O signals with Field Control Units in CENTUM VP automation systems. Operating on a 220-240V AC dual-redundant power supply, it securely communicates analog and contact signals while housing up to 8 I/O modules on a standard 19-inch rack.
Robust System Integration for Industrial Distributed Control
In complex process control environments such as oil refineries, chemical plants, and power generation facilities, reliable communication between field instrumentation and control processors is critical. The Yokogawa ANB10D-425/CU2N ESB Bus Node Unit serves as a core hardware interface within the Yokogawa CENTUM VP distributed control system (DCS) architecture. Engineered for high reliability, this node unit acts as a secure bridge that links analog and digital contact I/O signals from the field directly to the Field Control Unit (FCU) via a high-speed copper-based Enhanced Safety Bus (ESB).
Dual-Redundant Architecture and Power Stability
To eliminate single points of failure in mission-critical industrial loops, the ANB10D-425/CU2N model features a robust dual-redundant power supply configuration designed for 220-240V AC input voltages. By accommodating redundant power modules and dual communication interface slave modules, the unit maintains continuous operation even during power fluctuations or module maintenance. The standard 19-inch rack-mounted chassis houses up to 8 I/O modules, providing a compact, highly organized footprint for marshaling cabinets and remote instrument enclosures.
Seamless Communication and Diagnostics
The unit utilizes specialized ESB bus connector units (/CU2N option) to ensure secure physical connections and real-time data transmission integrity over distances up to 100 meters. Integrated diagnostic functions and status indicators allow maintenance personnel to monitor power status, communication health, and module performance continuously, minimizing unexpected downtime and ensuring maximum plant availability.
