ANB10D-420/CU2T/NDEL | Yokogawa | CENTUM VP ESB Bus Node Unit

Product Overview

The Yokogawa ANB10D-420/CU2T/NDEL serves as a vital expansion node for the CENTUM VP Distributed Control System (DCS). This unit facilitates high-speed communication between the Field Control Station (FCS) and remote I/O modules via a dual-resistant ESB bus interface. It enables the seamless scaling of I/O points across industrial facilities. We supply this unit as 100% Brand New and Original, serving as the direct, upgraded replacement for the legacy ANB10D/CU2T configuration.

Engineering Advantages

The ANB10D-420/CU2T/NDEL provides critical solutions for high-availability process control and system scalability:

• Eliminate Signal Reflections: The integrated /CU2T option provides a dedicated connector unit with an internal terminator. This hardware eliminates electrical "noise" and signal reflections on the ESB bus, ensuring data integrity across long cable runs between nodes.

• Pre-Licensed Scalability: The /NDEL suffix includes the software license for Node Expansion at the point of purchase. This removes the administrative burden of sourcing separate licenses when adding new I/O nodes to an existing CENTUM VP project.

• Fail-Safe Power Architecture: The -4 suffix indicates dual-redundant power supplies. If one power module fails, the secondary module assumes the full load instantly. This prevents node-wide shutdowns and ensures that the field I/O data remains visible to the operator at all times.

• Simplified Rack Integration: The unit includes specialized insulation bushes and standard M5 screws. These accessories simplify 19-inch rack installation while preventing ground loops and electromagnetic interference (EMI) from migrating through the rack frame.

FAQs

• Can the ANB10D-420/CU2T/NDEL replace the older ANB10D/CU2T? Yes, Yokogawa designates this specific model as a direct replacement. It maintains the same physical footprint while integrating the latest component revisions for improved thermal management.

• Does this unit support 110V AC power? The "2" in the suffix code specifically indicates a 220-240V AC configuration. If your site utilizes 100-120V AC, you must select the model with the "1" suffix code.

• What is the benefit of the dual-resistant ESB bus? The dual-resistant architecture provides two independent physical paths for data. If one ESB cable sustains physical damage, the node continues to communicate through the secondary cable, maintaining 100% process visibility.

• Is the NDEL software license physical or digital? The license is tied to the hardware's serial number and firmware. By ordering the /NDEL version, the hardware arrives ready for expansion within the Yokogawa engineering environment.
