Description
The Yokogawa EC401-50 S3 ESB Bus Coupler Module is a communication interface module used within the CENTUM VP and CENTUM CS 3000 Distributed Control System (DCS) platforms. Its primary function is to connect the Field Control Unit (FCU) with ESB Bus Node Units, enabling high-speed and reliable transfer of I/O data across the field network.
Operating at a transmission speed of 128 Mbps, the module supports up to nine node units and provides deterministic communication for process automation applications. The EC401-50 S3 supports both single-bus and dual-redundant bus architectures, allowing users to implement high-availability control systems with automatic redundancy.
