ANB10D-427/CU2t YOKOGAWA ESB Bus Node Unit

The Yokogawa ANB10D‑427/CU2T is a high‑reliability ESB (Enhanced System Bus) Bus Node Unit designed for distributed industrial control systems, particularly in Yokogawa automation

platforms like CENTUM VP and related field I/O infrastructures. The unit acts as a communication hub between field‑level I/O modules (analog, digital,

contact signals) and the Field Control Unit (FCU) over a dual‑redundant ESB network — ensuring robust,

deterministic data exchange and power delivery to connected I/O modules.

Frequently Asked Questions

Q1. What is the purpose of an ESB Bus Node Unit?
An ESB Bus Node Unit provides the interface between field I/O modules and the Field Control Unit (FCU) over the Enhanced System Bus (ESB). It aggregates analog and contact signals from sensors and actuators in the field and relays them to the FCU for processing, also supplying power to I/O modules.

Q2. What does “ANB10D‑427/CU2T” represent?

• ANB10D: Series for Node Units that support dual‑redundant ESB bus connections.

• 427: Specific model number within the ANB10D family.

• /CU2T: Connector Unit with Terminator option for the ESB bus (Part No. S9564FA), which helps properly terminate the bus and maintain signal integrity.

Q3. What does dual‑redundancy mean in this unit?
Dual‑redundant means the node unit can be configured with redundant power supplies and ESB communication paths,

so if one fails, the other continues operation — improving reliability in safety‑critical or high‑availability systems.
