Product Introduction

The Yokogawa ANB10D-420/CU2N is a robust ESB Bus Node Unit, part of Yokogawa’s CENTUM VP integrated production control system architecture. Designed to serve as a gateway between the control unit and I/O modules, this node unit forms a critical component in distributed control environments, especially in industries requiring high reliability and deterministic communication such as oil & gas, chemical, power generation, and water treatment.

It supports ESB (Enhanced Serial Bus) communication and enables high-speed, redundant data transfer across the control network. The model includes embedded diagnostics and can handle multiple I/O types through associated terminal modules. With support for redundancy and fault tolerance, the ANB10D-420/CU2N ensures seamless plant operation, contributing to Yokogawa’s reputation for operational excellence.
