Product Overview
The Yokogawa EC401-11 ESB Bus Coupler Module is a high-performance communication module designed for Yokogawa’s CENTUM VP system. It serves as an interface that connects the Field Control 单位 (FCU) with Node 单位s via the ESB bus, enabling real-time data transmission and system integration across various control architectures. This module supports both non-redundant and dual-redundant configurations and is specifically tailored for N-IO (Network-based I/O) and FIO (Field I/O) environments.
By enabling reliable communication over short distances (up to 10 meters) at high speed (128 Mbps), the EC401-11 significantly contributes to enhancing system reliability and scalability. It is also engineered for compatibility with a range / Field Control 单位s such as AFV30S/D, AFV40S/D, A2FV50S/D, and A2FV70S/D, ensuring integration flexibility.
