Introduction to the 140NRP31200 Ethernet Fiber Converter
Engineers upgrading legacy copper networks often face electromagnetic interference, distance limitations, and grounding issues. The Schneider 140NRP31200 solves these problems. This Modicon Ethernet fiber converter bridges electrical Ethernet and multimode optical fiber. It belongs to the Modicon Quantum automation platform. The module provides two fiber optic LC ports and two Ethernet RJ-45 ports. It operates at a wavelength of 1310 nm. With a receiver sensitivity of -30 dBm, it maintains reliable links even over long cable runs. This converter is an ideal replacement for aging copper-to-fiber modules in industrial control systems.
Key Technical Specifications
Optical Performance
The 140NRP31200 uses multimode fiber. It supports distances between two transceivers of 2000 m with 50/125 µm fiber and 3000 m with 62.5/125 µm fiber. Attenuation ranges are -23.5 to -14 dB for 50/125 µm and -20 to -14 dB for 62.5/125 µm. Receiver sensitivity is -30 dBm, and detected silence is -45 dBm. Rise/fall time is 3 ns. These specs ensure low-loss, high-speed data transmission.
Electrical and Power
Power dissipation is 5 W. Inrush current is 1 A at 5 V DC. Bus current requirement is 1000 mA. These values help you plan power budgets and avoid overloading backplanes.

Operating altitude is up to 2000 m. The housing is polycarbonate. Marking is CE. Product certifications include C-tick, TÜV, and Merchant Navy. Standards met are CSA C22.2 No 142, FM Class 1 Division 2, and UL 508.
Why Choose the 140NRP31200 for Your Network Upgrade
This converter directly replaces older copper-based Modicon communication modules. It eliminates ground loops and noise. The multimode fiber interface supports segment lengths up to 3000 m, far exceeding typical copper limits. The 1310 nm wavelength is optimal for low attenuation in multimode fiber. The LC connectors are small and secure. The RJ-45 ports allow seamless integration with existing Ethernet switches and PLCs. The module includes six LEDs for module status, fault, and channel link/activity. This simplifies troubleshooting and reduces downtime. For engineers planning a migration from legacy systems, the 140NRP31200 offers a proven, certified path.
Installation and Setup
Mount the module in a Modicon Quantum rack. Ensure the backplane provides 5 V DC with at least 1000 mA bus current. Connect multimode fiber cables with LC connectors to the fiber ports. Use RJ-45 cables for Ethernet devices. Verify link status via the green STS and FX LEDs. The red ERR LED indicates an internal fault. Keep the module within the operating temperature range. Do not exceed the specified humidity and altitude limits. Follow all local electrical codes and the manufacturer’s installation guide.
Maintenance and Reliability
Inspect the module periodically for dust or damage. Clean fiber connectors with approved cleaning tools. Check LEDs for normal operation. The 140NRP31200 has no moving parts, so wear is minimal. Its polycarbonate housing resists impact and chemicals. The wide storage temperature range allows for harsh environments. For maximum uptime, monitor the ERR LED and address faults promptly. This converter is designed for long service life in industrial settings.
Compatibility and Integration
The 140NRP31200 works with the Modicon Quantum automation platform. It integrates with Ethernet networks via RJ-45 ports. The fiber ports support multimode LC connections. It can link to other 140NRP31200 units or compatible fiber devices. The module meets UL 508, CSA C22.2 No 142, and FM Class 1 Division 2 standards. It also holds C-tick, TÜV, and Merchant Navy certifications. This makes it suitable for global deployments.
Selection Guide
Before purchasing, verify your fiber type (multimode 50/125 µm or 62.5/125 µm). Check that your power supply meets the 5 V DC, 1000 mA bus current requirement. Confirm rack compatibility with Modicon Quantum. The 140NRP31200 comes with a CE marking. For accessories, consult SpareTechPLC. They can advise on compatible LC connectors and cables. Always verify current lifecycle status and availability with SpareTechPLC before ordering.
