Yokogawa ANB10D-426/CU2N/NDEL CENTUM VP Node Unit for Dual-Redundant ESB Bus

Product Overview

The Yokogawa ANB10D-426/CU2N/NDEL functions as a high-performance interface node for the CENTUM VP distributed control system. This unit connects I/O modules to the Field Control Station (FCS) via a dual-redundant ESB bus, maintaining high-speed data synchronization. Engineered for harsh environments, this specific configuration incorporates G3-level environmental protection and an extended temperature range. We guarantee this product as 100% brand new and original, shipped in factory-sealed packaging.

Part Number Breakdown

The suffix and option codes define the specialized hardware capabilities of this ANB10D unit:

Technical Specifications

This unit meets the following industrial hardware standards:

• Power Supply: Dual-redundant 220–240 V AC

• Operating Temperature: -20°C to 70°C (Extended Range)

• Corrosion Resistance: ISA Standard G3 compliant conformal coating

• Bus Interface: Dual-Redundant ESB Bus

• Included Hardware: 2x S9562FA Connector Units

• Software Status: NDEL Node Expansion License included

• Explosion Protection: None (Basic Type)

• Condition: Brand New, Original Yokogawa Stock

Engineering Advantages

• Corrosive Atmosphere Survival: The G3-rated conformal coating protects internal circuitry against corrosive gases (such as $H_{2}S$ and $SO_{2}$). This ensures long-term reliability in chemical processing plants or refineries where standard electronics often fail due to terminal corrosion.

• Extreme Thermal Resilience: While standard units fail at 50°C, the "-6" option extends the operational threshold from -20°C up to 70°C. This allows for installation in outdoor cabinets or non-climate-controlled environments without risking logic errors or hardware shutdown.

• Seamless Capacity Expansion: The /NDEL license enables immediate node expansion within the CENTUM VP architecture. This eliminates the need for post-purchase software upgrades and allows for rapid scaling of I/O capacity during system commissioning.

• High-Availability Power: The dual-redundant power architecture ensures that a single power module failure or a tripped circuit breaker does not halt the process. The unit seamlessly draws power from the healthy secondary source to maintain bus communication.

FAQs

• What is the benefit of the /CU2N option?

  The /CU2N option provides two S9562FA connector units. These connectors facilitate the physical link between the ESB bus cables and the node unit, ensuring low-impedance signal transmission and secure mechanical fastening.

• Can I install this unit in an outdoor cabinet?

  Yes, provided the enclosure meets the necessary IP rating for moisture and dust. The unit’s -20°C to 70°C rating specifically supports environments with significant temperature fluctuations that would damage standard-grade hardware.

• Does this unit support hot-swapping of power modules?

  The dual-redundant configuration allows you to replace one power supply module while the other remains energized, ensuring the node stays online during maintenance.

• Is the /NDEL license already activated?

  The /NDEL suffix indicates the unit comes with the node expansion software authorization. You should verify your system's total node count within the CENTUM VP software environment during integration.
