What Is the 140NOA61110C?
The 140NOA61110C is an Interbus communications module from Schneider Electric’s Modicon Quantum series. It handles the data link between a Quantum controller and Interbus field devices, so machines and lines stay synchronized. Buyers typically specify it for material handling, packaging and textile machinery, where steady communication matters more than raw speed.
This is a practical spares choice, not a lab curiosity. If a line is down and the module is the suspect, you want a unit that matches the original part number exactly. Oil AutoTech supplies ready-to-ship automation spares for oil, gas and industrial sites, with fast dispatch worldwide.

What These Ratings Mean in Practice
The 0 to 40 degrees Celsius operating window tells you this module belongs in a controlled cabinet or clean plant room, not on a sun-baked skid. Keep panel cooling and filtration in good order and the unit stays inside its comfort zone.
The 80% RH non-condensing limit is the one people overlook. Condensation is the enemy of any communications board, so avoid washdown spray and cold-start humidity spikes near the enclosure. The 1000m altitude ceiling is generous for most inland plants but worth checking for high-elevation sites.
Where It Fits on the Plant Floor
Material handling is the classic fit. Conveyor zones, transfer cars and sortation loops rely on deterministic device communication, and an Interbus module keeps those handshakes predictable.
Packaging lines are the second common home. Fillers, cartoners and case packers run tightly sequenced motions, and a stable communications link reduces nuisance faults that eat into output.
Textile machinery rounds out the picture. Winding, spinning and finishing equipment often runs long shifts in clean indoor halls, which matches the module’s stated operating environment.
Integration and Selection Notes
Before you order, confirm three things: the host rack is Modicon Quantum, the field network is Interbus, and the existing module carries the exact part number 140NOA61110C. Mixing revisions or series is the fastest way to create a commissioning headache.
Interbus wiring into an existing network may require the correct connector and cable set. Confirm your cabling and any gateway needs with the supplier before dispatch, and our team can help you match the module to your panel.
Environmental checks matter too. Verify the cabinet stays within 0 to 40 degrees Celsius, keeps humidity below 80% RH without condensation, and sits under 1000m altitude. If any of those fail, address the enclosure first.
Maintenance and Reliability
Inspect the module periodically for loose connections, dust build-up and signs of heat stress. Follow the manufacturer’s safety manual for all work on the rack. Keep the enclosure closed and filtered, and the module will typically outlast the surrounding wiring.
Please verify current lifecycle status and availability with Oil AutoTech before ordering.
