Yokogawa ANB10D-415/CU2N/NDEL ESB Bus Node Unit | CENTUM VP

Product Overview

The Yokogawa ANB10D-415/CU2N/NDEL functions as a high-availability expansion interface for the CENTUM VP Distributed Control System. This ESB Bus Node Unit facilitates the connection of local and remote I/O modules to the Field Control Station (FCS). By utilizing a dual-redundant architecture, it ensures seamless data flow between field instruments and the processor. We provide this unit as 100% Brand New and Original, featuring pre-installed software licensing for immediate system expansion.

(Note: While some technical databases may incorrectly categorize this as an "Incremental Encoder," this hardware is officially a DCS Node Unit used for I/O signal management.)

Part Number Breakdown: ANB10D-415/CU2N/NDEL

Yokogawa employs the following suffix and option logic to define the hardware capabilities of the ANB10D series:

Engineering Advantages

The ANB10D-415/CU2N/NDEL solves critical connectivity and availability challenges in process automation:

• Eliminate Single Points of Failure: The dual-redundant power supply configuration ensures that the I/O node remains active even if one power module fails. The unit draws current from two independent sources, allowing for online replacement of a faulty supply without interrupting the process.

• Pre-Authorized System Scaling: The integrated /NDEL license removes the administrative hurdle of purchasing expansion keys separately. This allows engineers to increase the node count within the CENTUM VP project software immediately upon hardware installation, significantly accelerating commissioning timelines.

• Simplified Bus Connectivity: The /CU2N option provides the specialized connector unit required for the ESB bus. This interface simplifies daisy-chaining multiple nodes, ensuring stable, high-speed signal transmission across the system backplane without the risk of loose manual wiring.

• Optimized Power Compatibility: Suffix code '1' targets the 100-120V AC standard common in North American and Japanese facilities. The internal power units handle the electrical transients typical of industrial grids, protecting the sensitive FIO modules from voltage spikes.

FAQs

• What is the purpose of the /NDEL software license?

  The /NDEL license authorizes the DCS to recognize and communicate with additional node units beyond the base system configuration. Having this pre-installed on the ANB10D-415 simplifies the engineering process during plant expansion.

• Does this model include an internal terminator for the ESB bus?

  No, the /CU2N is a standard connector unit. If this node occupies the final position in an ESB bus chain, you must use a connector with a terminator (/CU2T) or add an external terminator to prevent signal reflections.

• Can I replace an ANB10S with this ANB10D model?

  Yes, the ANB10D (Duplex) provides higher reliability by supporting dual-redundant bus paths. Ensure your Field Control Station (FCS) has the necessary dual-redundant ESB bus ports to utilize the secondary communication channel.

• How do I handle the 10 kg weight during installation?

  Always utilize a standard 19-inch rack with adequate rail support. We recommend installing the unit in the lower or middle section of the cabinet to maintain a low center of gravity for the enclosure.
