Product Description
The ANB10D-426/CU2N/NDEL is a high-availability expansion interface designed for the Yokogawa CENTUM VP distributed control system (DCS). It serves as a communication bridge, connecting multiple I/O modules to the Field Control Unit (FCU) via the high-speed synchronous ESB bus.
Engineered for mission-critical automation, the unit features a dual-redundant power supply architecture that eliminates single points of failure, ensuring continuous and reliable process operation.
This model is configured for 220–240 V AC power environments and utilizes the /CU2N connector assembly, a standard ESB bus interface designed for daisy-chain configurations within control cabinets. The /NDEL designation indicates the inclusion of a software node expansion license, enabling seamless scalability in larger system architectures.
With its rugged 19-inch rack-mount design, the ANB10D-426/CU2N/NDEL provides a scalable and reliable solution for high-density I/O management in industrial applications.

Application Context
The ANB10D-426/CU2N/NDEL is widely used in large-scale process industries, including:
-
Oil refining
-
Chemical manufacturing
-
Thermal power generation
It is particularly suitable for expanding I/O capacity in both local and remote control cabinets where redundant power and high system availability are required. The integrated expansion license simplifies deployment, making it a flexible “plug-and-play” solution for system integrators scaling CENTUM VP architectures.
FAQ
What is the difference between the /CU2N and /CU2T connectors?
The /CU2N connector is a standard ESB bus interface without a built-in terminator and is used for intermediate nodes in a daisy-chain. For end-of-line nodes, a /CU2T connector (with integrated terminator) or an external terminator is required to maintain signal integrity.
Does this unit support DC power inputs?
No, the ANB10D-426/CU2N/NDEL is designed for 220–240 V AC input only (suffix -42). For facilities requiring 24 V DC or other voltage ranges, a different model suffix must be selected to ensure proper compatibility.
