Product Overview
The Yokogawa SB401-10 S2 Bus Interface Module is an industrial communication interface module used in Yokogawa Distributed Control Systems (DCS), especially within CENTUM CS3000 and CENTUM VP architectures. It is designed to support ESB bus communication between Field Control Units (FCU), system backplanes, and distributed I/O modules.
This module operates as a high-reliability ESB bus interface node, ensuring stable and synchronized data transmission across complex automation systems. The “S2” variant typically represents a specific hardware or configuration revision within the SB401-10 series, optimized for system compatibility and redundancy applications.
