Product Description
The ANB10D-410/CU2T is a critical infrastructure component within the Yokogawa CENTUM VP distributed control system (DCS). It functions as an ESB Bus Node Unit, providing a high-reliability interface for local and remote I/O modules while enabling deterministic communication with the Field Control Unit (FCU).
This model features a dual-redundant power supply system (100–120 V AC), ensuring uninterrupted operation even if one power source fails.
Equipped with the CU2T connector unit, this configuration includes integrated terminators (S9564FA), making it specifically designed for use as the final node in an ESB bus chain. The built-in termination prevents signal reflections and maintains communication integrity across the Extended Serial Backplane (ESB).

Deployment Applications
The ANB10D-410/CU2T is typically used as the terminal node in an ESB bus segment within facilities operating on 110 V AC infrastructure.
It is widely applied in:
-
Oil refineries
-
Pharmaceutical batch plants
-
Utility and power control systems
By serving as the end-of-chain node, it ensures proper bus termination, stabilizing the communication loop and maintaining Yokogawa’s deterministic timing performance across the control system.
Common Technical Queries
Q: Can this node be placed in the middle of a bus chain?
A: It is possible, but not recommended. The CU2T connector includes built-in termination, which is intended for the last node. For intermediate nodes, the CU2N (non-terminated) version should be used to avoid impedance mismatch.
Q: Does the ANB10D-410/CU2T support 24 V DC field devices?
A: Yes. While the node itself operates on 100–120 V AC, it supports a wide range of CENTUM VP I/O modules, including 24 V DC analog and digital modules, through the backplane interface.
