Schneider 140NOL91100 Modicon Quantum Transceiver for LON Networks

Introduction

When your industrial network demands reliable, high-speed communication over a Local Operating Network (LON), the Schneider 140NOL91100 Modicon Quantum transceiver delivers a proven solution. This module integrates seamlessly into Modicon Quantum rack systems, providing a dedicated LON interface that supports a data transfer rate of 1.25 Mbps. Designed for demanding environments, it operates within a temperature range of 0°C to 60°C and handles humidity from 10% to 95% RH, non-condensing. Whether you are upgrading an existing LON backbone or building a new control architecture, the 140NOL91100 offers the performance and durability required for continuous industrial operation.

Technical Specifications Breakdown

The 140NOL91100 operates on a 24 VDC power supply, ensuring compatibility with standard industrial power systems. Its LON interface uses the LonWorks (FTT-10) network protocol, enabling robust peer-to-peer communication at 1.25 Mbps. The module mounts directly onto a Modicon Quantum rack system, simplifying installation and reducing wiring complexity. Connections are secured via screw terminals, providing stable electrical contacts even in high-vibration environments. With a weight of only 0.06 lbs (0.03 kg), the transceiver adds minimal load to the rack, making it ideal for dense configurations. Compliance with CE, UL, and cUL standards confirms its adherence to international safety and quality requirements.

Industry Applications

In building automation systems, the 140NOL91100 connects lighting, HVAC, and access control subsystems over a LON backbone, enabling centralized monitoring and control. For manufacturing facilities, it links distributed I/O modules and sensors to a Quantum PLC, ensuring real‑time data exchange at 1.25 Mbps. The wide operating temperature range (0°C to 60°C) and humidity tolerance make it suitable for both climate‑controlled control rooms and harsher production floor environments. By integrating this transceiver, engineers can maintain a unified network architecture that reduces latency and improves system responsiveness.

Installation & Setup Guidance

Mount the 140NOL91100 onto any available slot in a Modicon Quantum rack system. Ensure the rack provides a stable 24 VDC power supply to the module. Connect the LON network cable to the screw terminal connector, observing proper polarity and termination as specified by the LonWorks (FTT-10) guidelines. Verify that the ambient temperature stays within 0°C to 60°C and that humidity remains below 95% RH, non‑condensing. After powering the system, check the module’s status indicators to confirm network communication. No special tools are required beyond standard screwdrivers for terminal tightening.

Maintenance & Reliability

Routine inspection of the 140NOL91100 should focus on the screw terminal connections to ensure they remain tight and free of corrosion. Periodically verify that the ambient environment stays within the specified temperature and humidity ranges, as extreme conditions can degrade performance over time. Because the module has no moving parts and draws low power from the 24 VDC supply, its expected service life is long under normal operating conditions. Including the transceiver in a regular preventive maintenance schedule helps avoid unexpected network interruptions and extends overall system reliability.

Compatibility & Integration

The 140NOL91100 is designed exclusively for the Modicon Quantum series from Schneider Electric. It integrates directly into Quantum racks and communicates using the LonWorks (FTT-10) protocol at 1.25 Mbps. This transceiver is compatible with any Quantum CPU or I/O module that supports LON networking. For systems using other protocols, a gateway may be required. Always verify that your existing Quantum backplane and power supply can accommodate the additional module before installation.

Selection Guide & Purchasing Advice

Before ordering the 140NOL91100, confirm that your network infrastructure uses LonWorks (FTT-10) and that your Quantum rack has an available slot. Check that your system’s 24 VDC power supply can handle the additional load. For large‑scale deployments, consider ordering spare units to minimize downtime.
