Schneider Electric 140NRP95400 Modicon Quantum Multi-Mode Fiber Optic Repeater

Product Overview

The 140NRP95400 provides high-speed signal regeneration and media conversion for the Schneider Electric Modicon Quantum platform. This fiber optic repeater facilitates long-distance communication between racks by converting coaxial electrical signals into multi-mode optical signals. It extends the reach of the Quantum network while providing total electrical isolation between drops. We supply this module as 100% Brand New and Original, ensuring peak data integrity for large-scale distributed control systems.

Engineering Advantages

• Extended Network Range: This repeater overcomes the physical limitations of copper cabling. It permits a distance of up to 3000 meters between transceivers, enabling the control of remote I/O racks in separate buildings or distant sections of a plant.

• Immunity to Electromagnetic Interference: By utilizing multi-mode fiber optics, the 140NRP95400 eliminates ground loops and protects the data stream from high-voltage EMI and RFI. This makes it essential for communications in power plants, substations, and environments with heavy motor traffic.

• Redundant Optical Paths: The dual ST fiber ports allow for flexible network topologies. Engineers can implement star or bus configurations to enhance network reliability and provide alternate data paths for the Quantum bus.

• Comprehensive Diagnostic Array: Seven integrated LEDs provide instantaneous status updates. Dedicated indicators monitor coaxial communication, optical link health, internal faults (ERR), and module readiness (RDY), significantly reducing the time required to diagnose network interruptions.

• Fast Signal Processing: A 20 ns rise/fall time ensures that the repeater introduces negligible latency into the Quantum bus. This maintains the high-speed synchronization necessary for real-time PAC performance and time-critical process control.

FAQs

• What fiber optic connectors does the 140NRP95400 use?

  The module features two standard ST (Straight Tip) connectors for the optical interface and one coaxial connector for the electrical drop.

• Can I mix different fiber sizes with this repeater?

  The 140NRP95400 supports 50/125 µm, 62.5/125 µm, and 100/140 µm multi-mode fibers. However, you must ensure that the cable and connectors remain consistent throughout a single link segment to avoid excessive signal attenuation.

• Does this module require external power?

  No. The 140NRP95400 draws its operating power directly from the Quantum backplane bus, requiring 700 mA at 5 V DC.

• Is this a current Schneider Electric product or a refurbished unit?

  We guarantee this is a 100% Brand New original factory product. It ships in original Schneider Electric packaging with the latest hardware revisions to ensure compatibility with your existing Quantum platform.
