Schneider 140NOL91110 Modicon Quantum Lonworks Transceiver for Reliable Data Communication

Introduction

When industrial networks demand robust and deterministic data communication, the Schneider 140NOL91110 transceiver delivers a reliable Lonworks interface for Modicon Quantum systems. This component addresses the pain point of integrating disparate automation devices by providing a standardized, low-bandwidth connection that ensures data integrity over long distances. Designed for stable operation across challenging environments, the 140NOL91110 is a key enabler for building management, process control, and remote monitoring applications.

Technical Specifications Breakdown

The 140NOL91110 operates with a Lonworks interface using TPT/XF-78 transmission at 78 kbps, ensuring efficient data flow for control and monitoring tasks. It requires a 24 V DC power supply with a current rating of 150 mA, making it energy-efficient and easy to integrate into existing 24 V systems. The transceiver mounts on a DIN rail, simplifying installation in crowded cabinets. For environmental resilience, it supports an operating temperature range of -20°C to 60°C and can be stored between -40°C and 85°C. Maximum operating humidity is 80% RH non-condensing, and it functions reliably up to 1000 meters altitude without derating. These specs ensure the module withstands typical industrial conditions.

Industry Applications

In building automation, the 140NOL91110 connects HVAC controllers, lighting systems, and energy meters to a central Lonworks network, enabling coordinated energy management. For process industries, it links remote I/O stations and sensors to a Modicon Quantum PLC, reducing wiring costs and improving data accuracy. In water treatment facilities, the transceiver's robust temperature range and humidity tolerance allow deployment in pump houses and outdoor enclosures without failure.

Installation & Setup Guidance

Mount the 140NOL91110 on a standard DIN rail within the control panel. Connect the 24 V DC power supply to the designated terminals, ensuring polarity matches. Use twisted-pair cabling for the Lonworks network, following TPT/XF-78 guidelines for maximum segment length and termination. Verify the bus voltage is stable at 24 V before powering up. After installation, configure the network address using the Modicon Quantum programming software to ensure proper node identification.

Maintenance & Reliability

To maximize uptime, inspect the 140NOL91110 periodically for dust accumulation and ensure ventilation around the DIN rail mount. Check the 24 V DC supply voltage regularly; deviations can cause intermittent communication errors. The transceiver's non-condensing humidity limit of 80% RH means avoid installing near steam or water leaks. Given its solid-state design, the module requires minimal routine care beyond environmental monitoring, reducing total cost of ownership.

Selection Guide & Purchasing Advice

Before purchasing, verify that your Modicon Quantum system has a free slot for the transceiver and that your network uses Lonworks protocol. Confirm the 24 V DC power supply can deliver at least 150 mA per module. For large networks, calculate the total current draw to avoid overloading the supply.
