Product Description

The ANB10D-F2 is a mission-critical interface node designed for Yokogawa CENTUM VP distributed control systems. It functions as a localized communication hub, linking field I/O modules to the Field Control Unit (FCU) via the Extended Serial Backplane (ESB) bus.

Engineered for high-availability architectures, this unit features a dual-redundant (active-active) power supply system optimized for 220–240 V AC operation, ensuring uninterrupted data acquisition even if one power source fails.

The ANB10D-F2 is a basic type (non-Ex) model intended for non-hazardous environments, providing a cost-effective yet reliable solution for expanding I/O capacity.

• Primary Function: ESB bus node (I/O expansion)

• Power Supply: Dual-redundant (220–240 V AC)

• I/O Capacity: 8 slots

• Application Type: Non-hazardous environments

• System Role: High-density I/O expansion node

Technical Specifications

Operational Applications

The ANB10D-F2 is widely used in:

• Refineries

• Chemical processing plants

• Power generation facilities

It is ideal for 220 V AC industrial environments, where:

• I/O signals are distributed closer to field instruments

• Wiring complexity and costs are reduced

• High-speed, deterministic communication with the FCU is required

By deploying multiple nodes, the system achieves scalable I/O expansion while maintaining high reliability and system integrity across large-scale plants.

Technical FAQ

Q: Does the ANB10D-F2 include the ESB bus connector units?
A: No. The base unit requires a separate connector selection:

• /CU2N for non-terminated nodes

• /CU2T for terminal nodes with integrated termination

Q: Can this unit be monitored for power health?
A: Yes. The CENTUM VP system provides real-time diagnostics for both redundant power supplies, enabling immediate detection and alarm of any power module failure to maintain system reliability.
