Description

Yokogawa ANB10D-425/CU2T S2 ESB Bus Node Units

The Yokogawa ANB10D-425/CU2T, also cataloged as the ANB10D ESB Bus Node Unit, operates as a dedicated hardware component for high-speed I/O signal interfacing within CENTUM VP and CENTUM CS 3000 DCS platforms. It provides dual-redundant power and communication paths to maintain continuous field bus operations.

Process Control Features

The ANB10D supports 4–20 mA HART loop connectivity and ensures channel-to-channel isolation to prevent cross-talk between analog and digital signals. The node unit maintains cold junction compensation (CJC) for thermocouple measurements and supports FOUNDATION Fieldbus communication for deterministic process control integration. Firmware updates are compatible across Style 2 revisions without interruption to the redundant ESB bus operation.

Frequently Asked Questions

Q: VnA: Can I hot-swap I/O modules without shutting down the ESB bus?
A: Yes, modules are hot-swappable within the dual-redundant configuration; ensure proper module seating and follow rack isolation procedures.

Q: VnA: What is the maximum current load on the ESB backplane per node?
A: The backplane supports the cumulative current of eight standard FIO modules plus two SB401 bus interfaces within rated specifications of the PW482 power modules.

Q: VnA: Are firmware updates for the ANB10D-425/CU2T backward-compatible?
A: Updates within the Style 2 revision maintain dual-redundant functionality and module communication integrity.

Field Installation Guidelines

• Mount the unit in a standard 19-inch rack using M5 × 4 screws.
• Ensure the ESB bus terminator (/CU2T) is installed on the last node of the network.
• Route power and communication cables separately to reduce EMI interference.
• Connect the grounding point on the chassis to facility earth to maintain EMC compliance.
• Avoid obstructing front and rear airflow; maintain minimum 50 mm clearance around the chassis.
• Verify dual-redundant power supply connection before commissioning the I/O modules.
