Product Description

The ANB10D-400 is a foundational ESB Bus Node Unit within the Yokogawa CENTUM VP distributed control system (DCS). It serves as the physical housing and communication gateway for I/O modules, enabling seamless data exchange between field instrumentation and the Field Control Unit (FCU).

By providing a high-speed ESB bus backplane, the ANB10D-400 ensures real-time process visibility and reliable control execution across distributed architectures.

This variant is configured for dual-redundant operation, supporting two independent power supply modules to eliminate downtime risks and enhance system availability. Built to Yokogawa’s industrial standards, the unit features a rugged construction suitable for long-term deployment in demanding environments.

With eight available I/O slots, the ANB10D-400 offers flexible expansion for both local and remote I/O configurations, making it a versatile component in scalable control systems.

Technical Specifications

Application Scenarios

The ANB10D-400 is widely used in high-availability industrial environments requiring reliable I/O processing and scalable control architectures, including:

• Petrochemical plants

• Oil refining facilities

• Power generation stations

It typically functions as an expansion node for AFV30 or AFV40 Field Control Units, allowing system designers to extend I/O capacity across multiple racks while maintaining redundant power and communication paths for critical processes.

FAQ

Is the connector unit included with the ANB10D-400?
No, the ANB10D-400 refers to the base node unit only. Connector units such as CU2N or CU2T must be selected separately depending on the node’s position within the ESB bus (intermediate or end-of-line).

Can I mix different types of I/O modules in this node?
Yes, the unit supports a wide range of Yokogawa FIO series analog and digital I/O modules. However, total power consumption must be calculated to ensure the installed power supply modules can support the combined load.
