Product Details
The Yokogawa ANB10D-425, also cataloged as the ANB10D ESB Bus Node Unit, operates as a dedicated hardware component for converting and transmitting field I/O signals to the Field Control Unit (FCU) within Yokogawa CENTUM VP CS 3000 systems. It routes analog and contact I/O data through the deterministic ESB bus architecture.

4-20 mA HART Loop Protocol and Channel Isolation
The ANB10D-425 node unit acts as a high-density backplane interface that routes 4-20 mA HART loop protocol signals directly to the system bus without introducing signal attenuation. Galvanic channel-to-channel isolation across the installed I/O cards prevents earth potential differences from corrupting low-level signal processing. The backplane bus structure enforces signal integrity across all slotted I/O positions while maintaining high-frequency HART digital communications across analog channels.
Frequently Asked Questions
Q: How does the dual-redundant power supply operate in the ANB10D-425?
A: The node unit contains two independent power supply modules operating in a load-sharing configuration. If one power source fails, the remaining unit immediately assumes the full power load without interrupting ESB bus communications.
Q: Are I/O modules installed in the ANB10D-425 hot-swappable?
A: Yes. I/O modules mounted on the node unit backplane can be replaced while the system remains powered and operational, provided the host FCU is configured for online module replacement.
Q: What is the primary purpose of the ESB bus connection on this node?
A: The ESB bus interface provides high-speed, deterministic optical/coaxial data link capability to transfer process variable data directly to the host Field Control Unit.
Field Installation Guidelines
- Secure the unit into a standard 19-inch instrument rack using four M5 retaining screws, maintaining at least 100 mm of vertical clearance above and below for convective cooling.
- Ensure both AC or DC power feed lines are connected to separate, circuit-breaker-protected power sources to maintain true dual-power redundancy.
- Terminate the ESB bus cable connectors firmly and ensure protective grounding conductors are bonded to the rack chassis with a ground resistance of less than 10 ohms.
- Verify that all I/O module slot filler plates are installed over unused slots to maintain proper internal enclosure airflow.
