Schneider 140XCA71706 Modicon Quantum Backplane Expander Cable 2m

Solving Field Device Connectivity Challenges

When expanding a Modicon Quantum automation system, engineers often face the challenge of connecting field devices across distances within a control cabinet. The Schneider 140XCA71706 backplane expander cable provides a reliable solution. This 2-meter cable uses PROFIBUS connectors at both ends to ensure seamless communication between backplane segments, eliminating signal degradation and simplifying wiring in dense installations.

Technical Specifications Breakdown

The 140XCA71706 is built for standard industrial environments. It operates within a temperature range of 0 to 60 degrees Celsius and tolerates humidity up to 80% non-condensing, both in operation and storage. With a maximum operating altitude of 1000 meters above sea level, it suits most factory floor and process plant applications. The cable's PVC construction provides durability against mechanical wear, while the IP20 protection class guards against dust and accidental contact. CE certification confirms compliance with European safety and environmental standards.

Industry Applications

In discrete manufacturing, the 140XCA71706 connects remote I/O racks to a central Quantum controller, enabling distributed control without signal loss. In process industries, it links expansion backplanes in larger cabinets, maintaining PROFIBUS communication integrity. The 2-meter length offers flexibility for cabinet layouts where standard shorter cables cannot reach.

Installation & Setup Guidance

Install the 140XCA71706 by connecting each PROFIBUS connector to the corresponding backplane port. Ensure the cable is routed away from high-voltage power lines to avoid electromagnetic interference. Secure the cable with cable ties to prevent stress on the connectors. Verify that the ambient temperature stays within 0 to 60 degrees Celsius and humidity below 80% non-condensing for optimal performance.

Maintenance & Reliability

Regularly inspect the 140XCA71706 for signs of wear on the PVC jacket or connector damage. Clean connectors with a dry, lint-free cloth if needed. Storing the cable in environments with humidity up to 80% non-condensing and temperatures within its rated range preserves its lifespan. The robust construction minimizes downtime, making it a cost-effective choice for long-term use.

Compatibility & Integration

The 140XCA71706 is designed exclusively for Schneider Electric Modicon Quantum systems. It works with any Quantum backplane that accepts PROFIBUS-style connectors. Ensure your system's backplane ports match the connector type before ordering. For integration with other automation networks, use appropriate gateways or converters as needed.
