Product Description

The ANB10D-420/CU2N/NDEL is a high-availability expansion interface designed for the Yokogawa CENTUM VP distributed control system. As the technological successor to the legacy ANB10D/CU2N series, this model delivers enhanced reliability and performance for critical industrial automation environments.

It functions as a communication bridge between Field Control Units (FCUs) and distributed I/O modules, enabling seamless and stable data transmission across the ESB bus.

Designed for flexibility, the ANB10D-420/CU2N/NDEL supports both AC and DC power input configurations, allowing adaptation to diverse plant utility infrastructures. The /NDEL designation indicates the inclusion of a software license for node expansion, ensuring scalable system growth in redundant architectures.

Built for demanding industrial conditions, the unit provides long-term operational stability in continuous process applications.

FAQ

What is the difference between the CU2N and CU2T connector units?
The /CU2N connector unit does not include a built-in terminator and is intended for intermediate nodes within an ESB bus daisy-chain. In contrast, the /CU2T version includes a terminator and is required for the final node in a bus segment.

Does this unit include the insulation bush for rack mounting?
Yes, the ANB10D-420/CU2N/NDEL is supplied with an insulation bush as a standard accessory, ensuring proper electrical isolation when installed in a 19-inch industrial rack.
