Yokogawa ANT502-5E Optical ESB Bus Repeater Module

Product Introduction

The Yokogawa ANT502-5E Optical ESB Bus Repeater Module is a high-performance communication module designed for distributed control systems (DCS) that require robust and reliable optical communication. This module functions as a repeater within the ESB (Enhanced System Bus) optical network, extending communication distances between the central control system and remote nodes while maintaining deterministic and high-speed data transmission.

The ANT502-5E employs fiber-optic technology to eliminate electromagnetic interference (EMI), ensuring stable signal integrity across industrial environments. This module is widely deployed in power generation, petrochemical plants, oil & gas facilities, and large-scale manufacturing systems. Its rugged construction, integrated diagnostics, and flexible mounting options make it suitable for demanding plant environments, ensuring continuous operation and easy maintenance.
