Product Description
The ANB10D-420/CU2T is a high-availability interface chassis designed for the Yokogawa CENTUM VP distributed control system (DCS). It serves as a localized communication hub, connecting field I/O modules to the Field Control Unit (FCU) via a dual-redundant Extended Serial Backplane (ESB) bus.
Engineered for mission-critical reliability, this unit features an active-active redundant power supply architecture, ensuring uninterrupted process control even if a single power source or hardware component fails.
Equipped with the CU2T connector unit, this model includes integrated 100-ohm termination resistors, making it the required terminal node at the end of an ESB bus chain. This prevents signal reflections and maintains communication integrity across the control system. It also offers improved thermal stability and durability as a modern replacement for legacy ANB10D/CU2T hardware.

Deployment Applications
The ANB10D-420/CU2T is commonly used in refineries, chemical plants, and power generation facilities operating on 220 V AC infrastructure.
It is specifically intended for use as the terminal node in a distributed I/O architecture, typically installed in:
-
Remote Instrument Enclosures (RIEs)
-
Centralized control cabinets
By providing proper termination and redundant power, it ensures stable communication, low error rates, and high system availability across the ESB bus network.
Technical FAQ
Q: Why is the CU2T version necessary for the final node in a chain?
A: The CU2T includes built-in termination resistors, which are required at the end of the ESB bus to prevent signal reflections and ensure stable communication. Without termination, the system may experience data errors or signal degradation.
Q: Can this unit be used with both AFV30 and AFV40 Field Control Units?
A: Yes. The ANB10D-420/CU2T is fully compatible with both AFV30 and AFV40 controllers, allowing flexible system expansion and smooth integration across different CENTUM VP configurations.
