Product Description
The ANB10D-415/CU2N/NDEL is a fundamental expansion component for the Yokogawa CENTUM VP control system. This ESB Bus Node Unit provides remote housing for I/O modules, enabling seamless communication with the Field Control Unit (FCU) via the Extended Serial Backplane (ESB) bus.
This unit is configured with a dual-redundant 100–120 V AC power supply, ensuring continuous field data acquisition even if one power source or module fails.
As a Basic Type node, it is intended for non-hazardous environments where explosion protection is not required. It includes the CU2N connector unit (non-terminated, for mid/start bus placement) and the NDEL software license, which authorizes node expansion within the control system.
Note: Despite some misclassifications, this is strictly a high-performance ESB communication node, not an encoder or signal processing device.

Operational Applications
The ANB10D-415/CU2N/NDEL is typically deployed in control cabinets to increase I/O density without requiring additional processors. It is widely used in manufacturing plants and utility facilities operating on 110 V AC infrastructure.
By distributing these nodes across a facility, engineers can reduce field wiring complexity while maintaining a high-speed, deterministic communication link to the central controller.
Technical FAQ
Q: Is the /CU2N connector suitable for the end of a bus line?
A: No. The CU2N is a non-terminated connector and should be used at the start or middle of the ESB bus chain. If the node is the last in the chain, a CU2T connector or external terminator is required to ensure signal stability.
Q: Does this unit support G3 environmental protection for corrosive gases?
A: No. The “5” suffix indicates a standard basic type. For corrosive environments with gases such as H₂S or SO₂, a model with an ISA G3 option should be selected.
