ANB10D-410/CU2N/NDEL CENTUM VP ESB Bus Node Unit | Yokogawa

Product Overview

The Yokogawa ANB10D-410/CU2N/NDEL acts as a high-availability I/O expansion hub for the CENTUM VP Distributed Control System (DCS). This unit facilitates the connection between the Field Control Station (FCS) and remote FIO modules via a dual-redundant Extended Serial Backplane (ESB) bus. By integrating dual-redundant power modules and a pre-installed node expansion license, it provides a "plug-and-play" solution for scaling industrial control networks. We supply this unit as 100% Brand New and Original, ensuring your critical infrastructure benefits from factory-certified hardware and long-term stability.

Part Number Breakdown: ANB10D-410/CU2N/NDEL

Yokogawa utilizes a structured suffix and option system to define the power, connectivity, and licensing of the ANB10D series:

Technical Specifications

The ANB10D-410/CU2N/NDEL incorporates robust industrial parameters designed for 24/7 operation:

• Bus Architecture: Dual-redundant ESB Bus (128 Mbps synchronization)

• Power Input: 100 - 120 V AC, 50/60 Hz

• Power Redundancy: Supports two hot-swappable power supply modules (Active-Active)

• I/O Capacity: Supports a wide array of Yokogawa Analog and Digital FIO modules

• Expansion License: Includes /NDEL (authorized node expansion license)

• Mounting: 19-inch rack-mountable (Occupies 5U of vertical space)

• Net Weight: 10 kg

• Status Monitoring: Front-panel LED indicators for Power and Bus communication

Engineering Advantages

The ANB10D-410/CU2N/NDEL addresses specific pain points in DCS deployment and facility expansion:

• Instantaneous Power Failover: The dual-redundant power configuration (-4) allows the unit to draw power from two independent AC sources. If one source or module fails, the secondary module carries the full load instantly. This ensures that the field I/O data remains visible to the control room without interruption during electrical maintenance.

• Streamlined System Scaling: The included /NDEL option provides the software license for Node Expansion directly with the hardware. This eliminates the delay of purchasing and activating separate software keys, allowing engineers to add the node to the CENTUM VP project database immediately upon physical installation.

• Enhanced Signal Reliability: The /CU2N option provides factory-certified connector units that ensure a secure, low-impedance connection to the ESB bus cables. This hardware-level reliability prevents data packet loss often caused by vibrations or poor contact in industrial environments.

• Optimized for Standard Racks: The 5U, 19-inch chassis fits into standard control cabinets. The unit includes insulation bushes as standard accessories, which isolate the chassis from the rack frame to prevent ground loops—a critical factor in maintaining the accuracy of sensitive analog measurement signals.

FAQs

• Does this unit include the ESB bus terminator?

  No. The /CU2N option provides standard connector units. If this node occupies the final position in your ESB bus chain, you must use a connector unit with a terminator (/CU2T) or install an external bus terminator.

• Can I use this unit in a 220V AC environment?

  No. The suffix code "1" specifically denotes a 100-120V AC input. Applying 220V AC will result in immediate hardware failure. For 220V applications, please request the ANB10D-420 model.

• Is the NDEL license already activated?

  The license is tied to the hardware serial number. When you add the node to your CENTUM VP Engineering station, the system recognizes the /NDEL capability, allowing the software to address the node without additional licensing prompts.

• How many I/O modules can I install in this node?

  The ANB10D chassis typically provides slots for up to 8 FIO modules, though the exact count depends on the specific power consumption of the installed modules (Analog vs. Digital).
