Technical Specifications
Main Features and Advantages
The Yokogawa ANB10D-425/CU2N offers a range of features and advantages that make it a cornerstone of the CENTUM VP DCS architecture. Its most significant strength is its role in enabling system redundancy. When a second ANB10D-425/CU2N is installed, the system automatically operates in a redundant mode. If the primary unit fails, the backup unit seamlessly takes over, preventing any interruption to process control. This failover capability is critical for ensuring the continuous and safe operation of a plant. The module’s high-speed Vnet/IP communication bus provides a robust and deterministic network for real-time control.
Reliable Design: The ANB10D-425/CU2N is designed for exceptional reliability, with a fanless, rugged construction that ensures a long service life in harsh industrial environments. Its compact size and hot-swappable design allow for quick and easy replacement without needing to shut down the entire system, minimizing downtime. The module also features built-in diagnostics that continuously monitor its own health and the status of the I/O modules it is connected to, providing a clear indication of any issues. This integrated approach to diagnostics simplifies troubleshooting and maintenance. The Yokogawa ANB10D-425/CU2N‘s combination of high reliability, redundancy, and compact design makes it a highly effective solution for large-scale process automation.
Application Field
The Yokogawa ANB10D-425/CU2N is an integral part of the CENTUM VP distributed control system, which is used in a wide array of large-scale, mission-critical process industries. Its primary application fields are in:
- Oil and Gas: Used in refineries, offshore platforms, and pipelines to control complex processes like distillation, cracking, and fluid transfer.
- Chemical and Petrochemical: Employed in chemical plants for managing reactions, blending, and other critical processes.
- Power Generation: Used in power plants to control boiler operations, steam turbines, and balance-of-plant systems.
- Pharmaceuticals and Biotechnology: Applied in manufacturing facilities to ensure precise control over batch processes and clean-in-place operations.
- Pulp and Paper: The ANB10D-425/CU2N provides the communication backbone for controlling everything from pulping to drying. In all these applications, the Yokogawa ANB10D-425/CU2N ensures that a plant’s field devices and control logic are connected in a reliable and high-performance manner, which is essential for safety, efficiency, and quality.

Installation and Maintenance
Pre-installation preparation: Before installing the Yokogawa ANB10D-425/CU2N, ensure the node cabinet is correctly mounted and that the Vnet/IP cables are properly terminated. The ANB10D-425/CU2N is a module that slides into its designated slot in the node cabinet. Once installed, the power supply is connected to the cabinet, and the unit is ready for configuration within the CENTUM VP engineering software. The wiring of I/O modules to field devices is performed separately.
Maintenance recommendations: Routine maintenance for the ANB10D-425/CU2N is minimal due to its durable and modular design. The system’s self-diagnostics continuously monitor the health of the module. In the event of a fault, the module will indicate a status change, and the issue will be reported in the CENTUM VP software. The hot-swappable design allows for quick and easy replacement of the module without needing to power down the entire cabinet, which simplifies maintenance and minimizes downtime.
