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

Product Overview

The Yokogawa ANB10D-415/CU2N acts as the high-availability interface for expanding I/O capacity within the CENTUM VP Distributed Control System (DCS). This ESB Bus Node Unit facilitates high-speed communication between the Field Control Station (FCS) and FIO modules. By supporting dual-redundant ESB bus paths and power modules, this unit maintains continuous process visibility and control. We provide this hardware as 100% Brand New and Original, ensuring your automation architecture meets strict factory specifications for mission-critical reliability.

Part Number Breakdown: ANB10D-415/CU2N

Yokogawa defines the configuration of the ANB10D series through a modular suffix and option system:

Technical Specifications

The ANB10D-415/CU2N incorporates robust electrical and mechanical parameters to handle high-density I/O traffic:

• Communication Bus: Dual-redundant ESB Bus (Extended Serial Backplane)

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

• Redundancy: Supports dual-path bus and dual-power module hot-swapping

• Mounting: 19-inch Rack Mounting (Requires 5U space)

• Included Hardware: 2 pieces of S9562FA Connector Units

• Installation Accessories: M5 x 4 screws and insulation bushes

• Weight: 10 kg (Net)

Engineering Advantages

The ANB10D-415/CU2N addresses specific industrial installation and uptime challenges:

• Mitigate Ground Loop Interference: The unit includes specialized insulation bushes (accessories). These components isolate the chassis from the rack frame, preventing circulating ground currents from corrupting sensitive analog I/O signals.

• High-Speed Signal Integrity: The /CU2N option provides two S9562FA connector units. These factory-certified connectors ensure a low-impedance path for the 125 Mbps ESB bus, preventing data packet loss in electrically noisy environments near VFDs or high-voltage switchgear.

• Uninterrupted Process Uptime: The dual-redundant power supply (Suffix -4) configuration allows the node to draw current from independent AC sources. If one power module fails, the secondary module carries the full load instantly, permitting the replacement of the faulty unit without interrupting the control logic or field data flow.

• Flexible Cabinet Integration: Designed for 19-inch rack mounting, the unit utilizes standard M5 screws. This allows engineers to consolidate extensive I/O points into high-density cabinets, reducing the overall footprint in the control room or Remote Instrument Enclosure (RIE).

FAQs

• Does the /CU2N option include terminators? No. The /CU2N refers to the standard Connector Unit. If this node sits at the end of an ESB bus chain, you must use a connector unit with a terminator (/CU2T) or add an external terminator to prevent signal reflection.

• Can I use this unit with 220V AC power? No. This specific configuration (Suffix 1) targets 100-120V AC. Applying 220V AC will damage the internal power modules. For 220V applications, you require the ANB10D-425 model.

• How does the unit handle vibration in industrial racks? The 10 kg robust chassis and M5 secure mounting system withstand the mechanical vibrations common in process plants. The included insulation bushes also provide a degree of mechanical damping between the unit and the rack frame.

• Is this unit compatible with the latest CENTUM VP software? Yes. The ANB10D-415 remains a standard component for current CENTUM VP deployments, providing full compatibility with LFS1500 and related control functions.
