Overview
The Yokogawa EB401-10 ER Bus Interface Master Module is a key component in Yokogawa’s CENTUM VP distributed control system (DCS), designed to establish high-speed and reliable communication between field control stations and I/O modules. This module functions as the master unit on the ER Bus, enabling deterministic and redundant data transmission across multiple subsystems.
Moreover, its advanced communication technology ensures precise data exchange with minimal latency, supporting mission-critical process automation applications. Built to meet Yokogawa’s rigorous quality standards, the EB401-10 delivers stable operation, easy configuration, and long-term dependability in harsh industrial environments.
