YOKOGAWA ANT502-53 OPTICAL BUS REPEATER MODULE

Description:

The Yokogawa ANT502-53 Optical ESB Bus Repeater Module is used in distributed control systems to extend communication distance over the Enhanced Serial Bus (ESB) network using optical fiber. Commonly installed in Yokogawa CENTUM DCS node units and optical ESB systems for long-distance data transmission. Maintenance teams and system integrators use this part for extending network range, replacing failed repeater modules, or maintaining reliable communication between distributed control system components.

Applications:

The Yokogawa ANT502-53 is commonly used in industrial automation environments where long-distance communication between field control units and remote I/O nodes is required. It is frequently applied in oil & gas, chemical plants, and power generation systems to extend ESB communication over optical fiber. The module converts electrical ESB signals into optical signals, allowing stable, noise-resistant transmission over distances up to several kilometers in harsh industrial environments.
