Yokogawa ANB10D-425-CU2N CENTUM VP series ESB Bus Node Unit

Configured for distributed control network expansion in CENTUM VP platforms, the Yokogawa ANB10D-425-CU2N (ANB10D-425-CU2N ESB Bus Node Unit) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

• ANB10D: Base platform designating the node unit for dual-redundant ESB bus architectures.
• -4: Dual-redundant power supply configuration option.
• 2: Power supply voltage rating for 220-240 V AC operation.
• 5: Basic hardware type with no explosion protection.
• -CU2N: Connector unit option for ESB bus integration without terminal resistors.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation

The internal signal processing architecture provides rigorous channel-to-channel isolation across connected analog modules, protecting sensitive measurement circuits from common-mode voltage spikes and ground loops. Communication subsystems handle standard 4-20 mA HART loop protocols natively, ensuring uninterrupted diagnostic data overlay and precise process variable scaling without introducing conversion latency or signal attenuation across extended control loops.

Frequently Asked Questions

Q: How does the -CU2N connector unit differ in network topology placement compared to terminal node variations?

A: The -CU2N configuration is designed for intermediate or daisy-chain drop points along the Extended Serial Backplane (ESB) bus, requiring downstream continuation cables rather than integrated terminal resistors.

Q: How does the dual-redundant power supply architecture manage active-active switchover during input voltage loss?

A: The dual 220-240 V AC power modules operate in a balanced load-sharing configuration; if one power rail experiences voltage drop or total failure, the redundant module instantly assumes full load demand without causing a reset or communication interruption on the backplane bus.

Field Installation Guidelines

• Rack Mounting: Secure the 19-inch rack-mount chassis into the cabinet profile using all designated mounting points to withstand mechanical vibrations and prevent structural misalignment.
• Shielded Cabling: Route all ESB bus communication cables through dedicated metallic wireways, ensuring that cable shields are properly grounded to the enclosure bus bar to suppress electromagnetic interference.
• Thermal Management: Maintain a clear vertical airflow path above and below the 10 kg unit enclosure to allow natural convection cooling within the specified 0 to 50 deg C operating temperature window.
