The Schneider Electric Modicon Premium 490NRP95400 Fiber Optic Repeater is a critical networking component for expanding the architecture of Modicon Premium automation systems. It is specifically designed to interface with the FIPIO (Factory Instrumentation Protocol I/O) fieldbus, a high-speed deterministic network used for connecting CPUs with remote I/O, experts, and drives.

Industrial installations often require distributing I/O over long distances or in areas with extreme electromagnetic interference (EMI). Copper-based networks are susceptible to this noise and have length limitations. The 490NRP95400 solves these challenges by converting the network to a light-based signal transmitted over fiber optic cable, which is completely immune to EMI and enables significantly longer transmission distances.

Key Features & Benefits:

• Noise Immunity: Fiber optic communication is completely immune to electromagnetic interference (EMI), radio frequency interference (RFI), and ground loops, ensuring data integrity in electrically noisy environments like steel mills or power plants.

• Long-Distance Extension: Enables extension of the FIPIO network far beyond the limitations of copper cabling (up to several kilometers with the appropriate fiber type), providing unparalleled layout flexibility.

• Electrical Isolation: Provides complete galvanic isolation between network segments, protecting sensitive PLC equipment from voltage surges, lightning strikes, and differences in ground potential between buildings.

• High-Speed and Secure: Supports the full 2.5 Mbps speed of the FIPIO network and offers a secure data transmission medium that is extremely difficult to tap into without detection.

• Redundant Power Supply Options: Features connections for two separate power supplies, enhancing the reliability of the repeater itself within the network infrastructure.

• LED Diagnostics: Includes comprehensive status LEDs for power, network activity, and link status on both the electrical and optical sides, enabling quick fault finding and maintenance.

Typical Applications:

• Extending Modicon Premium PLC systems across large facilities or between separate buildings.

• Protecting control networks in areas with high EMI (e.g., welding shops, large motor control centers).

• Creating electrically isolated network segments for safety and equipment protection.

• Securing data transmission against eavesdropping in sensitive applications.

• Water treatment plants, manufacturing facilities, and transportation systems.

The 490NRP95400 is an essential solution for engineers designing robust, scalable, and reliable Modicon Premium automation architectures that must perform reliably in challenging conditions.
