Yokogawa ANT502-50 Optical ESB Bus Repeater Slave Module

Overview

The Yokogawa ANT502-50 is an Optical ESB Bus Repeater Slave Module. It extends the Ethernet Serial Bus (ESB) communication distance up to 5 km using optical signals. This module converts electrical ESB signals to optical form and back, enhancing signal reliability. It supports chain and star network topologies and installs in various Yokogawa control units like FCUs, ANT10U, ANB10, and ANB11. Additionally, it can transmit cabinet environmental data to the control system for monitoring.
