Why the 140XCA71706 Belongs in Your Quantum Spares Kit
Downtime on a Modicon Quantum line rarely announces itself. When a backplane link fails, the whole rack stops talking. The Schneider Electric 140XCA71706 backplane expander cable exists for exactly that moment: a 2-meter cable with PROFIBUS connectors positioned at both ends, built to keep field devices connected inside Quantum automation systems.
If you maintain oil, gas, or process automation racks, this is the kind of practical spare that pays for itself the first time a cable is damaged during service work. Oil AutoTech keeps fast-dispatch spares for oil, gas and industrial automation applications, so you are not waiting weeks for a replacement.
What This Cable Actually Does
The 140XCA71706 is a backplane expander cable from Schneider Electric’s Modicon Quantum product line. Its job is straightforward: extend connectivity between backplane positions so field devices and modules continue communicating without interruption. At 2 meters, it gives engineers enough reach for a range of cabinet configurations without adding unnecessary slack.
Both ends carry PROFIBUS connector types. That matters because connector integrity is where most intermittent faults begin. A properly seated PROFIBUS connector on each end reduces the chance of signal loss and keeps the segment stable during vibration or routine maintenance.
Integration Note
When wiring this cable into a PROFIBUS network, the physical connection may require an external gateway or connection module depending on your architecture. Confirm the correct cables and gateways with your supplier before commissioning.

Built for Real Industrial Conditions
The PVC jacket handles regular industrial use while maintaining performance integrity. The cable operates between 0 degrees Celsius and 60 degrees Celsius, which suits standard control-room and cabinet environments. Humidity tolerance reaches 80% in non-condensing conditions for both operating and storage environments, so the cable is fit for active setups and shelf storage alike.
It also functions at altitudes up to 1000 meters above sea level without affecting performance. The IP20 protection class indicates adequate shielding against dust and mechanical impacts in cabinet-mounted installations. CE certification confirms compliance with applicable safety and environmental standards.
Where Engineers Deploy It
Quantum rack expansion. When a Modicon Quantum system needs additional backplane reach, the 140XCA71706 provides a clean, manufacturer-matched connection rather than a workaround.
Oil and gas control cabinets. In upstream and midstream facilities, cabinets are often dense and service access is tight. A 2-meter cable with connectors at both ends simplifies routing and reduces strain on adjacent modules.
Planned replacement programs. Maintenance teams that stock this cable avoid expedited freight costs and unplanned production losses when a link fails during a shift.
Selection Advice Before You Order
Verify three things before purchase: your Quantum rack configuration, the required cable length, and the connector type at each termination point. The 140XCA71706 uses PROFIBUS connectors at both ends, so confirm this matches your existing setup.
