YOKOGAWA ANT502-50 S1 OPTICAL ESB BUS REP MODULE

Description:

The Yokogawa ANT502-50 S1 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 bus systems for long-distance communication. 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 ANT502-50 S1 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, power generation, and large-scale manufacturing systems to extend ESB communication using optical fiber. The module converts electrical ESB signals into optical signals, allowing stable, noise-resistant transmission across extended distances in harsh industrial environments.
