Schneider Electric 140NOE35100 Modicon Quantum Fiber Optic

Product Overview

The 140NOE35100 stands as a specialized fiber optic Ethernet communication module within the Schneider Electric Modicon Quantum series. Engineered for environments prone to electromagnetic interference, this module utilizes 10BASE-FL connectivity to ensure isolated and secure data transmission over long distances. By facilitating high-speed communication within a local backplane, it serves as a critical gateway for PLC data exchange, providing a robust backbone for industrial automation architectures that demand zero signal degradation.

Core Technical Advantages

This module features a unique dual-port 10BASE-FL configuration using ST-style connectors, specifically designed for fiber optic media. The hardware is treated with a professional-grade conformal coating, protecting internal circuitry against humidity, dust, and chemical contaminants. It is built to operate seamlessly at altitudes up to 2,000 meters, supporting global deployment in various industrial climates. Its flexible power architecture allows for integration into systems ranging from 24 VDC to 230 VAC, ensuring universal compatibility across the Quantum product line.

Technical Specifications

Installation & Maintenance

The module must be installed exclusively in a local backplane to ensure proper bus communication and timing. When connecting fiber optic cables, ensure the ST-style connectors are clean and fully seated; a light audible click confirms a secure link. Weighing approximately 0.45 kg, the unit is easily handled but requires careful alignment with the backplane pins to prevent mechanical damage. Periodic inspection of the fiber ports is recommended to prevent signal loss caused by dust accumulation on the optical lenses.

Engineering Advantages

The unit offers superior noise immunity compared to copper-based Ethernet, making it the preferred choice for motor control centers or facilities with high-frequency noise. The conformal coating provides an extra layer of defense in "harsh" environments, extending the lifecycle of the 140NOE35100 significantly. With full compliance for UL, CE, and CSA standards, this module meets the safety and insurance requirements for high-stakes infrastructure and manufacturing projects.

Technical FAQs

Q1: Can I use standard RJ45 copper cables with the 140NOE35100?
A1: No, this module is specifically designed for fiber optic media using ST-style 10BASE-FL connections and does not support copper cabling.

Q2: Does this module support remote I/O backplanes?
A2: No, the hardware is designed strictly for support in local backplanes only to maintain communication speed and integrity.

Q3: What is the benefit of the conformal coating on this specific model?
A3: The coating protects the PCB from corrosion and moisture, allowing the module to maintain a 95% humidity tolerance without the risk of electrical short-circuits.
