Yokogawa ANB10D-427/CU2N CENTUM VP ESB Bus Node Unit

Product Overview

The Yokogawa ANB10D-427/CU2N functions as a high-availability I/O expansion hub within the CENTUM VP Distributed Control System (DCS). This ESB Bus Node Unit enables the connection of local and remote FIO modules to the Field Control Station (FCS), facilitating high-speed data acquisition and process control. By utilizing a dual-redundant architecture for both communication and power, it maintains uninterrupted signal flow between field instruments and the processor. We supply this unit as 100% Brand New and Original, ensuring your control infrastructure meets the highest factory-certified standards.

Part Number Breakdown: ANB10D-427/CU2N

Yokogawa specifies the functional capabilities of the ANB10D series through the following alphanumeric suffix logic:

Engineering Advantages

The ANB10D-427/CU2N addresses the core requirements of modern process automation facilities:

• Eliminate Signal Loss via Bus Redundancy: The dual-redundant ESB bus interface provides two independent physical paths for data. If one ESB cable sustains physical damage, the unit maintains 100% process visibility through the secondary path, preventing the loss of critical field data.

• Continuous Power Availability: The -4 suffix indicates a dual-redundant power supply configuration. This allows the unit to draw power from two independent sources. If one power module fails, the healthy module assumes the full load instantly, permitting "hot-swapping" or online replacement without interrupting I/O operations.

• Simplified Hardware Integration: The /CU2N connector unit facilitates rapid daisy-chaining of multiple I/O nodes. This standardized interface reduces wiring errors and ensures stable, high-speed signal transmission across the system backplane, even in cabinets with high-density cabling.

• High-Voltage Grid Compatibility: Specifically engineered for 220-240V AC environments, the internal power circuitry filters industrial line noise and handles voltage transients typical of large-scale manufacturing grids, protecting sensitive FIO modules from electrical interference.

FAQs

• Does the /CU2N option include an internal terminator?

  No. The /CU2N is a standard connector unit without a terminator. If this node occupies the final position in your ESB bus chain, you must use a /CU2T connector unit or install an external terminator to prevent signal reflections.

• Can I replace an ANB10S with this ANB10D model?

  Yes. The ANB10D (Duplexed) provides higher reliability than the ANB10S (Single). Ensure your Field Control Station (FCS) features dual-redundant ESB bus ports to utilize the secondary communication channel provided by this unit.

• What mounting hardware does the unit require?

  The unit fits standard 19-inch racks. We recommend utilizing the specified M5 screws and insulation bushes to prevent ground loops and ensure the 10 kg chassis remains stable against industrial vibrations.

• Is this unit compatible with 110V AC power?

  No. The suffix code "2" specifically denotes a 220-240V AC input. For 110V AC environments, you must select the model with the "1" suffix code to prevent hardware damage.
