Product Description
The ANB10D-425/CU2T S2 is a high-availability expansion node designed for the Yokogawa CENTUM VP distributed control system. It enables integration of I/O modules and serves as a communication bridge between field instrumentation and the Field Control Unit (FCU) via the Extended Serial Backplane (ESB) bus.
This S2 revision is engineered for demanding industrial environments and features a dual-redundant power supply (220–240 V AC) to ensure uninterrupted operation even in the event of a single power failure.
A key feature is the CU2T connector unit, which includes an integrated terminator, making it ideal for use as the final node in an ESB bus chain. This prevents signal reflection and ensures stable, high-integrity communication.
Additionally, the unit supports ISA G3 environmental protection, allowing reliable operation in corrosive gas environments with temperatures ranging from -20°C to 70°C.

Operational Applications
The ANB10D-425/CU2T S2 is commonly deployed in refineries, power plants, and chemical processing facilities that operate on 220 V AC infrastructure.
It is particularly suited for Remote Instrument Enclosures (RIEs) in harsh or corrosive environments, where high reliability and robust communication are essential. By serving as the terminal node in a distributed I/O network, it ensures proper signal termination and stable ESB bus communication back to the central control system.
Technical FAQ
Q: Why is the "T" in the CU2T connector important?
A: The "T" indicates that the connector includes an integrated terminator, which is required at the end of an ESB bus chain to prevent signal reflections and maintain communication integrity.
Q: Does this unit support G3 corrosive environments?
A: Yes. The S2 revision supports ISA G3 protection, making it suitable for environments with corrosive gases such as H₂S and SO₂, commonly found in chemical and offshore facilities.
