Product Description
The ANB10D-420/CU2N/NDEL serves as a high-availability expansion interface for Yokogawa’s CENTUM VP distributed control system. This ESB Bus Node Unit enables seamless integration of local and remote I/O modules, bridging field signals to the Field Control Unit (FCU) via a dual-redundant Extended Serial Backplane (ESB) bus.
Engineered for mission-critical environments, this configuration utilizes a dual-redundant 100–120 V AC power supply, ensuring uninterrupted I/O processing even if one power circuit fails.
Designed as a drop-in replacement for legacy ANB10D/CU2N units, it incorporates the CU2N connector unit (without terminator) for standard bus linking and includes the NDEL software license for node expansion within system projects. Its rugged 19-inch rack-mount chassis is built to withstand the electrical and thermal demands of industrial installations.

Installation Context
The ANB10D-420/CU2N/NDEL is typically deployed in 100–120 V AC infrastructure environments, common in North America and certain Asian facilities. It enables horizontal system expansion by housing analog and digital I/O modules that interface directly with field instrumentation.
Through the ESB bus, the unit maintains deterministic communication performance required for high-speed PID control loops and safety interlocking systems, ensuring stable and reliable plant operation.
Technical FAQ
Q: Can this unit be used as the last node in an ESB chain?
A: No. The CU2N configuration does not include a terminator, so it is intended for the start or middle of the chain. For end-of-line installation, a CU2T version or an external terminator is required to prevent signal reflection.
Q: What is included in the mounting kit?
A: The unit includes four M5 mounting screws and insulation bushings, ensuring proper mechanical installation and electrical isolation from the rack frame.
