Product Description
The Yokogawa EB401-50 ER Bus Interface Master Module is a communication module developed by Yokogawa Electric Corporation. It is used to establish connectivity between ESB Bus Node Unités or Compact Field Control Unités (for FIO) and ER Bus Node Unités (Remote Nodes) via the ER bus. This module plays a vital role in distributed control systems by providing reliable data transmission channels across remote unités. 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.
