SNT501-S13 S1 YOKOGAWA Optical Bus Repeater Module

Extended Transmission Distance: The SNT501-S13 S1, when paired with a master module, enables ESB Bus transmission distances of up to 5 km per stage. 

Signal Integrity and Reliability: By converting electrical signals to optical and back, the module significantly enhances signal integrity over long distances, mitigating issues like electromagnetic interference (EMI/RFI) and signal degradation that can affect traditional copper-based bus systems.

Flexible Connection Methods: The module supports both star type and chain type connections, providing flexibility in designing the network architecture to suit various plant layouts and requirements.

Compact and Lightweight: With a weight of approximately 0.3 kg, it's designed for ease of installation and integration into existing control cabinets.

Integration with Yokogawa Systems: It seamlessly integrates with other Yokogawa DCS components, specifically connecting via optical fiber to a master repeater module and via ESB Bus cable to an ESB Bus Interface Module (SSB401) on safety node units .

The YOKOGAWA SNT501-S13 S1 is an Optical Bus Repeater Module used within Yokogawa's Distributed Control Systems (DCS), such as the CENTUM series. It forms a critical part of the optical ESB Bus communication system, working in conjunction with a master module (like the SNT401) to extend network distances.
