製品紹介
The Yokogawa ANT401-50/CU1N Optical ESB Bus Repeater Master Module is a high-performance optical communication module engineered for large-scale distributed control systems (DCS). As the master 台 in an ESB (Enhanced System Bus) optical repeater network, it enables long-distance, high-speed, and deterministic data communication between the central control system and remote field nodes.
This module leverages fiber-optic technology to eliminate electromagnetic interference, ensure signal integrity, and extend the communication range across industrial plants. The ANT401-50/CU1N is widely deployed in mission-critical applications where high reliability, system scalability, and redundancy are essential. Its rugged construction, integrated diagnostics, and flexible mounting options make it suitable for industries such as oil & gas, power generation, petrochemical processing, and automated manufacturing systems.
