Product Description

ESB Bus Infrastructure Overview

The ANB10S (Model: ANB10S) is a foundational ESB Bus Node Unit engineered for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). This unit functions as the primary hardware interface connecting Field Control Units (FCUs) to remote I/O subsystems. By facilitating high-speed, deterministic communication over the Enhanced System Bus (ESB), the ANB10S (Node Unit: ANB10S) ensures that field data is synchronized with the controller logic at the sub-millisecond intervals required for advanced process automation. This specific assembly is pre-configured with the SB401-10 (Bus Module: SB401-10) and the PW481-10 (Power Supply: PW481-10), providing a ready-to-deploy solution for expanding system I/O capacity.
