Yokogawa ANT502-53S1 Optical Bus Repeater Module

The Yokogawa ANT502-53S1 Optical ESB Bus Repeater Module extends ESB network distance by converting ESB electrical signals to optical signals for long-distance data transmission. In Yokogawa CENTUM DCS environments, it is commonly installed in node units and control cabinets for long-distance data communication. Key specifications include transmission up to ~5 km with optical fiber, support for chain and star topologies, and up to 8 nodes depending on configuration, with current consumption around 0.5 A and a weight of about 0.25 kg; the G3 option variant operates from -20°C to 70°C. Installation is in node units such as ANB11, AFV series, or repeater units, and the module provides signal regeneration for reliable long-distance communication across distributed DCS architectures. Common replacements include Yokogawa ANT512 Optical Bus Repeater Module, Yokogawa ANT401 Optical Bus Repeater (Master), and Yokogawa AIP502 Communication Module.
