Product 描述
The Yokogawa EB401-50 ER Bus Interface Master Module is a communication module developed by 横河 Corporation. It is used to establish connectivity between ESB Bus Node 单位s or Compact Field Control 单位s (for FIO) and ER Bus Node 单位s (Remote Nodes) via the ER bus. This module plays a vital role in distributed control systems by providing reliable data transmission channels across remote 件s. It is specifically designed to be installed in models such as ANB10S, ANB10D, AFF50S, AFF50D, AFV10S, and AFV10D.
The EB401-50 supports dual-redundant configurations when two modules are installed, enhancing communication reliability and system robustness.
