2026-04-20T00:19:47-07:00

Type: ESB Bus Node Unit
Price: 66.00

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.

Part Number Breakdown

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

-4 | Power Redundancy | Equipped with Dual-redundant power supplies
2 | Voltage | 220 - 240 V AC power supply input
0 | Protection | Basic type (Non-explosion protection)
/CU2T | Option | Connector Unit with Terminator (Includes 2x S9564FA)

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.
