Overview
Signal degradation over long distances can disrupt critical control loops and cause costly downtime. The Schneider 140NRP95401C Coated Fibre Optic Repeater addresses this challenge by regenerating optical signals with precision. As part of the Modicon Quantum automation platform, this unit delivers consistent performance in demanding environments. With a power dissipation of only 5 W and a bus current requirement of 750 mA, it integrates efficiently into existing systems.

The Schneider 140NRP95401C uses single-mode fiber and offers a receiver sensitivity of -25 dBm, ensuring clear signal capture even in low-power conditions. Its ability to detect silence at -45 dBm makes it ideal for noise-sensitive communication links.
Application Scenarios
In a typical industrial network, the 140NRP95401C extends the distance between a controller and remote I/O racks over fiber optic cable. For example, in a water treatment plant where control cabinets are spread across 500 meters, this repeater maintains signal integrity without degradation. Similarly, in a mining operation where electromagnetic interference is high, the fiber optic repeater provides isolation and reliable data transmission. The 5 W power dissipation and 750 mA bus current allow for easy integration into existing quantum backplanes.
Compatibility and Integration
The 140NRP95401C is designed for the Modicon Quantum automation platform from Schneider Electric. It connects directly to the backplane and requires no additional configuration for basic operation. The two LC fiber optic ports and one coaxial port provide flexible connectivity to various network topologies. This device supports single-mode fiber, which is preferred for long-distance runs up to 10 km. Installers should verify that the fiber optic cable type and connector style match the repeater's specifications.
Selection Guide
Before purchasing a replacement or new 140NRP95401C, confirm that your system uses a Modicon Quantum backplane and that the bus current capacity can accommodate the 750 mA draw. Also check the ambient temperature range of your installation location—0 to 60°C—and ensure adequate ventilation. For high-availability systems, consider stocking a spare unit to minimize downtime.
