ANB10D-445/CU2N/NDEL | Yokogawa CENTUM VP ESB Bus Node Unit

Product Overview

The Yokogawa ANB10D-445/CU2N/NDEL functions as a high-availability Node Interface Unit (NIU) for the CENTUM VP Distributed Control System. This unit expands I/O capacity by bridging local and remote I/O modules with the Field Control Unit (FCU) via the high-speed ESB bus. The "D" designation confirms its Duplicated (Redundant) architecture, ensuring continuous process communication even during a hardware fault. This specific configuration operates on a 24 V DC power system, making it ideal for standard industrial DC power grids.

Condition: 100% Brand New and Original Factory Sealed.

Part Number Breakdown: ANB10D-445/CU2N/NDEL

Yokogawa utilizes a structured coding system to define the hardware and licensing requirements of the NIU:

• ANB10D: Duplicated Node Interface Unit (for FIO).

• -4: Dual-redundant power supply configuration.

• 4: 24 V DC power supply input.

• 5: Basic hardware type (No explosion protection).

• /CU2N: Includes Connector Units for ESB Bus (2 pieces of Part No. S9562FA).

• /NDEL: Includes Software License for Node Expansion.

Engineering Advantages

• Fault-Tolerant 24V DC Architecture: The unit utilizes dual-redundant 24V DC power supply modules. If one power source fails, the secondary module carries the full load instantaneously, preventing node dropouts and maintaining process integrity.

• Seamless Node Expansion: The integrated /NDEL license eliminates the need for separate software procurement during system scaling. This simplifies the procurement process and accelerates the deployment of additional I/O nodes.

• Optimized Signal Integrity: The /CU2N option provides two S9562FA connector units. These specialized connectors secure the ESB bus physical layer, preventing signal attenuation and protecting the high-speed data backbone from electromagnetic interference (EMI).

• Robust Load Capacity: At 10 kg net weight, the unit features industrial-grade chassis construction. It withstands the mechanical stresses and thermal loads typical of high-density DCS cabinets, ensuring a 20+ year service life.

• Native DC Integration: Unlike AC models, the ANB10D-445 integrates directly into 24V DC battery-backed systems. This provides a simpler power architecture for facilities prioritizing DC-only control rooms.

FAQs

• What is the difference between ANB10D and ANB11D?

  The ANB10D utilizes the standard ESB Bus for local/near-distance communication, whereas the ANB11D supports the Optical ESB Bus for long-distance remote I/O requirements up to 5km.

• Does the /NDEL option require additional activation?

  The /NDEL code indicates that the node unit comes with the necessary license for node expansion. You must register the license within the CENTUM VP engineering station to recognize the new node.

• Is this unit suitable for hazardous area installation?

  No. The suffix "5" identifies this as a basic type without explosion protection. You must install this unit in a non-hazardous area or within a suitably rated explosion-proof enclosure if used in a Class I Div 2 environment.
