Product Overview
The Yokogawa ANT401-5E is a high-performance optical bus repeater main module designed to facilitate long-distance and noise-immune data transmission in industrial control networks. Developed by Yokogawa Electric Corporation, a global leader in industrial automation, the ANT401-5E acts as the central node in a fiber optic repeater system, extending communication distances and ensuring stable signal integrity in distributed control systems (DCS).
By converting electrical signals into optical signals and vice versa, this module plays a critical role in reducing electromagnetic interference (EMI) and enhancing the reliability of plant-wide automation networks. It is typically deployed in CENTUM VP and STARDOM systems, supporting real-time data exchange over optical fiber in hazardous and high-noise environments.
