Product Overview
The Yokogawa EC401-10 ESB Bus Coupler Module is a critical communication component in the CENTUM VP integrated production control system. It connects the Field Control 单位 (FCU) to the Node 单位s (ANB10S, ANB10D, ANT401, etc.) via the high-speed ESB (Enhanced Serial Bus). Designed specifically for N-IO/FIO systems, the EC401-10 supports both single and dual-redundant configurations to ensure system reliability and data integrity in industrial automation environments.
