Fibre Optic Repeater Schneider 140NRP95400 Modicon Quantum

Product Overview

The 140NRP95400 functions as a high-performance fiber optic repeater specifically engineered for the Schneider Electric Modicon Quantum automation platform. It facilitates robust communication across Remote I/O (RIO) S908 networks by converting coaxial signals into optical signals. This module enables long-distance data transmission while providing total electrical isolation between network segments. We provide this unit as 100% Brand New and Original, ensuring full compliance with your critical control system requirements.

Technical Specifications

Engineering Advantages

• Eliminate Ground Loops: By utilizing multi-mode fiber optics, the 140NRP95400 provides complete galvanic isolation. This effectively solves common industrial noise issues and protects the Quantum backplane from lightning strikes or high-voltage surges on the network line.

• Extended Network Reach: Traditional coaxial RIO segments face strict distance limitations. This repeater extends your network architecture up to 3000 meters, allowing for the centralized control of widely distributed remote I/O drops.

• Real-Time Diagnostics: The front panel features a comprehensive LED array. Dedicated LEDs monitor coaxial communication status, optical link activity, module readiness (RDY), and internal faults (ERR/FAULT), allowing technicians to troubleshoot link integrity at a glance.

• High-Speed Signal Integrity: With a rise/fall time of only 20 ns and a 20 dB dynamic range, the module maintains high-speed data throughput without signal degradation, even in environments with heavy electromagnetic interference (EMI).

FAQs

• Can the 140NRP95400 work with single-mode fiber? No. This module specifically supports multi-mode fiber (50/125 µm, 62.5/125 µm, or 100/140 µm). Attempting to use single-mode fiber will result in excessive signal loss and link failure.

• What is the maximum distance supported between two transceivers? The distance depends on the fiber core size. It supports up to 2000 meters for 50/125 µm fiber and up to 3000 meters for 62.5/125 µm or 100/140 µm fiber.

• Does this module require external power? The module draws its operating power directly from the Quantum backplane (700 mA bus current requirement). Ensure your power supply module (PSM) has sufficient capacity to handle the load.

• What does a solid red ERR LED indicate? A solid red ERR LED signifies an internal module failure or a critical hardware fault. In such cases, the module typically requires replacement to restore network segment communication.
