Product Overview
The Yokogawa EC401-50 ESB Bus Coupler Module is a high-performance communication interface designed to link Field Control ユニットs with Node ユニットs via the ESB (Extension System Bus). It plays a vital role in extending the field I/O capabilities / the CENTUM VP system. Built to support both single and dual-redundant configurations, it ensures reliability and efficient data communication at high speeds.
This module is compatible with FIO-based Field Control ユニットs such as AFV30S, AFV30D, AFV40S, AFV40D, A2FV50S, A2FV50D, A2FV70S, and A2FV70D, making it ideal for advanced industrial automation applications that require consistent uptime and robust I/O integration.
