140XCA71706 Schneider Electric Modicon Quantum Expander Cable 2m

Product Overview

The 140XCA71706 by Schneider Electric is a dedicated backplane expander cable engineered for the Modicon Quantum automation platform. This 2-meter cable is a critical accessory for system scalability, allowing for the seamless connection of additional racks and field devices to the primary controller. Weighing 0.45 kg (1.00 lbs), it facilitates high-speed data transmission across the backplane, ensuring that expanded I/O configurations maintain the same communication integrity as local rack installations.

Technical Specifications

Engineering Advantages

The 140XCA71706 hardware is designed to withstand standard industrial stress while providing an IP20 protection rating against dust and mechanical impact. The use of PROFIBUS-style connectors at both terminals ensures a secure, vibration-resistant physical link between Quantum backplanes. Its PVC construction remains flexible yet tough, supporting an operating temperature range of 0°C to 60°C and altitudes up to 1000 meters. This reliability is vital for maintaining constant uptime in distributed I/O architectures where signal loss could result in system-wide logic interruptions.

Technical FAQs

Q1: Is this cable compatible with other PLC series?
A1: The 140XCA71706 is specifically designed for the Schneider Electric Modicon Quantum series backplane expansion and is not recommended for other PLC platforms.

Q2: Can I use this cable in high-humidity environments?
A2: Yes, it is rated for up to 80% non-condensing humidity during both operation and storage, making it suitable for most standard factory environments.

Q3: Does the length affect the data transmission speed?
A3: At 2 meters, this cable is factory-validated to ensure that signal propagation delay remains within the strict tolerances required by the Quantum backplane timing specifications.
