Distributed I/O Expansion Solution – Schneider Electric 140XCA71706 | Modicon Quantum
Where This Product Is Used
The Schneider Electric 140XCA71706 is a backplane expander cable engineered for the Modicon Quantum PLC platform. It is deployed in environments where rack-to-rack I/O expansion is required within a single control system architecture. Typical application scenarios include:
- Large-scale process automation – Oil & gas refineries, chemical plants, and water treatment facilities requiring distributed I/O across multiple racks in a single cabinet or remote panel.
- Power generation & utilities – Turbine control panels and substation automation systems where Quantum racks must be physically separated but logically linked.
- Automotive & heavy manufacturing – Assembly line PLCs with high I/O counts that exceed a single rack’s slot capacity, requiring seamless backplane extension.
- Building management systems (BMS) – HVAC, fire suppression, and access control panels using Modicon Quantum as the central controller with expanded I/O modules.
- Mining & metals – Conveyor control, crusher automation, and smelter process control where rugged, reliable rack interconnects are critical.

Application-Specific FAQ
Q: Is the 140XCA71706 compatible with all Modicon Quantum rack sizes?
A: Yes. It is designed to interconnect standard Quantum backplane racks (6, 10, and 16-slot) within the 140-series platform. Verify rack model compatibility with your system integrator for non-standard configurations.
Q: Can this cable be used in a hot-standby (HSBY) Quantum system?
A: The 140XCA71706 is a backplane expander cable and is not part of the HSBY redundancy interconnect. HSBY systems use dedicated fiber or copper redundancy cables (e.g., 140XCA71202). Consult your Quantum system architecture documentation.
Q: What is the maximum number of racks that can be connected using this cable?
A: The Modicon Quantum architecture supports up to 16 local I/O racks. The number of expander cables required depends on your rack layout. Contact our technical team for a rack expansion design review.
Q: Do you provide a warranty on this part?
A: Yes. Konmask.com provides a 90-day functional warranty on all parts. Extended warranty options are available — contact us for details.
Q: Can I return the part if it is not compatible with my system?
A: We accept returns within 30 days of delivery for unused, unopened items in original packaging. Please contact support@konmask.com to initiate a return authorization.
