ANB10D-420/CU2T | Yokogawa | CENTUM VP Node Unit for Dual-Redundant ESB Bus

Product Overview

The Yokogawa ANB10D-420/CU2T serves as a high-availability node unit designed specifically for the CENTUM VP Distributed Control System (DCS). This unit facilitates seamless communication between the Field Control Unit (FCU) and various I/O modules. Unlike standard nodes, the ANB10D architecture supports dual-redundant ESB bus configurations, ensuring zero signal interruption even if one communication path fails. We supply this unit as 100% Brand New and Original, providing the technical integrity required for mission-critical industrial processes.

The suffix and option codes define the specific hardware capabilities of this unit:

Technical Specifications

The ANB10D-420/CU2T integrates robust electrical specs to handle continuous heavy-load processing:

• Communication Interface: Dual-Resistant ESB Bus (Redundant)

• Input Power: 220 V to 240 V AC (Wide range tolerance)

• Frequency: 50/60 Hz

• Redundancy: Supports both Power Supply and Communication Redundancy

• Termination: Integrated CU2T module with S9564FA terminators

• Mounting: Standard 19-inch rack-mount compatibility

• I/O Module Slots: Supports multiple Yokogawa I/O modules per node

Engineering Advantages

• Fault-Tolerant Communication: The dual-redundant ESB bus architecture eliminates single points of failure. If a cable breaks or a port fails, the system automatically switches to the secondary path without dropping process data.

• Power Reliability: Two independent power modules load-share the system requirements. This allows for live replacement of a power module or survival during the loss of a primary power circuit.

• Simplified Bus Termination: The /CU2T option includes the specific S9564FA terminators. This simplifies the end-of-line configuration for the ESB bus, preventing signal reflection and noise without requiring external termination blocks.

• Direct DCS Integration: This unit communicates natively with CENTUM VP controllers. Engineers save hours on configuration because the system recognizes the ANB10D hardware automatically upon connection to the ESB bus.

FAQs

• Does the ANB10D-420/CU2T include the ESB bus cables? No, the unit includes the connector unit and terminators (/CU2T), but you must specify and purchase the ESB bus cables separately based on the distance between your FCU and the node.

• Can I use this unit in a single-bus (non-redundant) setup? While the ANB10D supports redundancy, it can operate in a non-redundant mode. However, for cost-sensitive applications that do not require dual paths, the ANB10N model is the standard alternative.

• What happens if one power supply fails? The secondary power supply unit immediately takes over the full load. The DCS will trigger a system alarm to alert the operator, allowing for a "hot" replacement of the failed module without shutting down the entire node.

• Is this unit compatible with 110V AC environments? No. The "2" in the suffix code designates a 220-240V AC power supply. For 100-120V AC environments, you must order the ANB10D-410 variant.
