6GK1502-3CB10 | Siemens | PROFIBUS Optical Link Module

Product Description

The Siemens 6GK1502-3CB10 is a PROFIBUS optical link module from the SIMATIC NET portfolio, designed to extend PROFIBUS DP and PA networks through fiber-optic transmission. By converting RS-485 electrical signals into optical signals, this module enables stable and noise-immune communication across long distances and electrically harsh industrial environments.

The 6GK1502-3CB10 is typically used in factory automation, process automation, and distributed control systems where electromagnetic interference, grounding differences, or large plant layouts make copper cabling impractical. Support for flexible and redundant network structures allows this module to be integrated into both standard and high-availability PROFIBUS architectures.

Application Scope

This optical link module is suitable for legacy and existing PROFIBUS installations requiring extended transmission distance, galvanic isolation, and improved network robustness. Typical use cases include production lines, process plants, utilities, and outdoor or large-scale industrial facilities.
