Product Description
The SNT501-13 is an optical communication repeater designed to extend the Extended System Bus (ESB) within Yokogawa CENTUM VP and Yokogawa CENTUM CS 3000 control architectures. Operating as the slave-side module of an optical ESB link, it receives high-speed control data via fiber optic cable from a master repeater and converts it back into electrical signals for local I/O backplane distribution.
By leveraging fiber optic transmission, the SNT501-13 provides full galvanic isolation between distributed plant areas. This eliminates ground loops and protects control systems from lightning strikes, high-voltage surges, and severe electromagnetic interference.
The module enables long-distance geographic distribution of I/O nodes—far beyond the limitations of copper-based ESB cables—while preserving deterministic communication performance required for real-time process synchronization. It is engineered for seamless integration and stable operation in large-scale industrial facilities.

Application
The SNT501-13 is commonly used in:
-
Tank farm automation systems
-
Water and wastewater treatment plants
-
Offshore oil & gas platforms
-
Multi-building industrial complexes
It is particularly suitable for connecting remote I/O racks across long distances or in high-EMI environments where copper communication would be unreliable.
Technical FAQ
What is the maximum supported distance?
Depending on fiber type and the paired master module, the SNT501-13 typically supports transmission distances from approximately 500 meters up to 5 kilometers without signal degradation.
Does the SNT501-13 support redundant configurations?
Yes. In high-availability systems, dual SNT501-13 modules can be installed to create a redundant optical ESB path, ensuring continuous operation even if one fiber link fails.
