In chemical or oil processing facilities, electrical interference and explosive atmospheres demand safe, isolated communication systems. The PSI-MOS-PROFIB/FO 660 E allows copper PROFIBUS lines to be converted into fiber optic connections that remain immune to noise and grounding issues. Its alarm contact and diagnostic function help maintenance teams identify signal weakening early, preventing process interruptions and ensuring reliable data transfer in hazardous areas such as reactor zones or distillation sections.
Ships and offshore platforms experience strong vibration and electrical disturbances that can disrupt traditional copper cabling. By using this converter to shift data transmission onto fiber optics, communication between distributed sensors, drives, and controllers remains stable across long cable distances. Its rugged build and industrial approvals make it a dependable solution for shipboard automation, engine monitoring, and ballast control systems where downtime is costly.
In automotive welding or metal fabrication lines, electromagnetic interference often corrupts control signals. Integrating the PSI-MOS-PROFIB/FO 660 E isolates communication paths and converts them to optical fiber, completely shielding the data stream from EMI. With automatic baud rate adjustment and optical monitoring, it guarantees uninterrupted production by ensuring consistent data exchange between PLCs and intelligent devices throughout high-noise manufacturing zones.
Large utility or wastewater treatment facilities require communication across long distances where copper signal strength declines. The converter extends the PROFIBUS network using fiber optics, maintaining clear, distortion-free communication between control centers and remote field units. Its built-in monitoring and relay output provide predictive maintenance capability, alerting operators to potential link degradation before a breakdown occurs—ensuring system stability in critical public infrastructure.
