Product Overview
Downtime on a Modicon Quantum line gets expensive fast. The 140NOL91110 from Schneider Electric is a Quantum transceiver built to keep Lonworks data moving across your automation system. It plugs into the Modicon Quantum platform and handles the communication layer that many process and utility installations depend on.
This is a practical, single-purpose module: a Lonworks interface transceiver with TPT/XF-78 transmission at 78 kbps. If you run Quantum hardware and need a ready-to-ship spare, this unit is built for the job.
Key Parameters That Matter
Lonworks Interface at 78 kbps
The 140NOL91110 uses a Lonworks interface with TPT/XF-78 transmission running at 78 kbps. That rate suits control-level data exchange — status, commands, and process values — where deterministic behavior beats raw bandwidth. It is not a high-throughput backbone device, and it is not meant to be.
24 V DC Power, 150 mA Draw
The transceiver runs on a 24 V DC supply and draws 150 mA. Bus voltage is also 24 V. That low current draw keeps panel loading predictable and simplifies power budgeting when you add or replace modules.
Environmental Envelope
Operating temperature spans -20°C to 60°C. Storage handles -40°C to 85°C. Humidity tops out at 80% RH non-condensing in both states. Maximum altitude is 1000 meters above sea level without derating, for operation and storage alike. In a climate-controlled rack room, these limits are comfortable. In an unconditioned cabinet near a furnace or compressor, they are the numbers to check first.
DIN Rail Mounting, 6.80 kg
The unit mounts on DIN rail, so it drops into standard Quantum racks and enclosures. Shipping weight is 15.00 lbs (6.80 kg).
Where It Fits
Process skids and utilities. Lonworks is common in building automation, metering, and utility-adjacent control. A Quantum rack feeding a Lonworks segment needs a transceiver that speaks the protocol cleanly. This is that part.
Legacy Quantum expansions. Plants running older Quantum systems often need spares that match the existing architecture. The 140NOL91110 keeps the Lonworks segment alive without a platform migration.
Replacement and upgrade work. When a transceiver fails, the fastest path back to production is a like-for-like swap. Matching the exact model avoids re-engineering the network segment.
Integration Notes
Lonworks segments frequently require an external gateway or connection module when tying into plant Ethernet or a DCS. Confirm your cabling, terminators, and gateway selection with your supplier before commissioning. Oil AutoTech offers hands-on technical selection help for exactly this kind of question.
Selection Checklist
Before ordering, verify:
- Your rack is Modicon Quantum and the slot supports this transceiver
- Your Lonworks segment uses TPT/XF-78 at 78 kbps
- Panel supply provides 24 V DC at 150 mA or better
- Ambient stays within -20°C to 60°C and 80% RH non-condensing
- Site altitude is at or below 1000 meters
Please verify current lifecycle status and availability with Oil AutoTech before ordering.
