Schneider Electric Modicon Quantum Backplane Expander Cable | 140XCA71706

Product Overview

The 140XCA71706 serves as the high-speed data link between multiple racks within the Schneider Electric Modicon Quantum automation platform. This specialized 2-meter (6.6 ft) cable enables the expansion of the local I/O bus, allowing a single processor to control modules across secondary backplanes. We supply this unit as 100% Brand New and Original, ensuring low-impedance signal transmission and structural integrity for critical control networks.

Technical Specifications

The 140XCA71706 provides a precise physical and electrical bridge for rack-to-rack communication:

• Cable Length: 6.6 ft (2 m)

• Primary Destination: Backplane Expander Systems

• Product Compatibility: Specifically designed for 140XBE10000 expander modules

• Connection Category: Specialized PLC Bus Interconnect

• Material Construction: Industrial-grade shielded multi-core cabling

Engineering Advantages

• Local Bus Seamless Extension: This cable facilitates the extension of the Quantum backplane bus beyond a single rack. It allows engineers to scale I/O capacity without implementing complex Remote I/O (RIO) or Distributed I/O (DIO) drop architectures.

• Optimized Signal Integrity: Original Schneider Electric engineering ensures that the 140XCA71706 maintains the strict timing and voltage requirements of the Quantum bus. This prevents data packet loss and bus errors often caused by non-genuine or degraded cabling.

• Simplified Rack Layout: The 2-meter length provides sufficient reach to connect adjacent racks in standard 800mm or 1000mm wide control cabinets. Its flexible jacket allows for tight-radius bends, easing the cable management process in densely packed enclosures.

• Robust Connection Security: The connectors feature secure locking mechanisms. These prevent accidental disconnection caused by cabinet vibrations or mechanical shocks in heavy industrial environments like stamping plants or turbine halls.

FAQs

• Which expander modules require the 140XCA71706 cable?

  This cable specifically connects two 140XBE10000 backplane expander modules. One module acts as the transmitter in the primary rack, while the second acts as the receiver in the expansion rack.

• Can I use this cable for Modicon M340 or M580 systems?

  No. The 140XCA71706 belongs exclusively to the Modicon Quantum platform. The M340 and M580 series utilize different expansion bus technologies (such as BMXXBE series cables).

• Is there a maximum distance limit for backplane expansion?

  Yes. Backplane expansion relies on high-speed parallel bus communication, which is distance-sensitive. Schneider Electric limits local expansion to specific cable lengths (like this 2m version) to ensure timing synchronization. For longer distances, you must transition to a Remote I/O (RIO) architecture.

• Does the cable arrive in original factory packaging?

  Absolutely. We guarantee every 140XCA71706 is 100% Brand New and ships in original Schneider Electric packaging to ensure the product remains free from kinks, shielding damage, or connector corrosion.
