Reliable Expansion for Modicon Quantum Systems
When your automation layout demands flexible placement of I/O modules or remote racks, the Schneider 140XCA71706 backplane expander cable provides a straightforward solution. This 2-meter cable extends the backplane bus within Modicon Quantum systems, allowing you to position field devices where they are most effective without compromising signal integrity.
Technical Specifications Breakdown
The 140XCA71706 is engineered for consistent performance in industrial environments. Key parameters from the manufacturer include:
- Cable Length: 2 meters – sufficient reach for common cabinet layouts and rack-to-rack connections.
- Connector Types: PROFIBUS connectors at both ends ensure a secure, standardized interface for automation networks.
- Material: Durable PVC jacket protects against abrasion and typical industrial contaminants.
- Environmental Range: Operates from 0 °C to 60 °C ambient temperature, with humidity tolerance up to 80% (non-condensing).
- Protection Class: IP20 rating guards against solid objects larger than 12.5 mm, suitable for enclosed control panels.
- Certifications: CE marked, confirming compliance with applicable EU safety and environmental directives.
These specifications make the 140XCA71706 a reliable choice for standard industrial conditions, avoiding the need for specialized environmental enclosures in most factory floor applications.
Industry Applications
Scenario 1: Distributed I/O in Manufacturing Lines
In a production line where multiple Modicon Quantum racks must be spaced apart, the 140XCA71706 provides the necessary bus extension. The 2-meter length allows one rack to be placed near sensors while the controller remains in a central cabinet, reducing wiring complexity and improving signal quality.
Scenario 2: Retrofit of Existing Control Panels
When upgrading an older system, space constraints often force relocation of modules. This cable enables you to keep the existing backplane while adding a remote expansion rack, minimizing downtime and rewiring costs.
Scenario 3: Testing and Commissioning Setups
During system validation, temporary rack connections are common. The robust PVC jacket and PROFIBUS connectors withstand repeated connect/disconnect cycles, making the 140XCA71706 suitable for test benches and commissioning carts.
Installation & Setup Guidance
Proper installation ensures reliable communication. Follow these practical steps:
- Verify Cable Orientation: The PROFIBUS connectors are keyed – align the connector notch with the receptacle on the backplane module before inserting. Do not force the connection.
- Secure the Cable: Use cable ties or routing channels to keep the 140XCA71706 away from sharp edges and high-voltage power cables. This prevents mechanical stress and electrical noise coupling.
- Check Bend Radius: Although the PVC jacket is flexible, avoid bending the cable tighter than a 10x cable diameter radius to prevent internal conductor damage.
- Confirm Termination: Ensure that the backplane expander module at each end is properly terminated (if required by your system configuration). Refer to the Modicon Quantum hardware manual for termination resistor settings.
Maintenance & Reliability
The 140XCA71706 requires minimal routine care. Periodically inspect the cable for cuts, kinks, or crushed sections, especially near connector strain reliefs. Clean connectors with a dry, lint-free cloth if dust accumulates. The IP20 rating means the cable is not intended for washdown areas; keep it inside enclosures rated for the environment. With proper handling, this cable delivers years of trouble-free service, reducing unplanned downtime.
Compatibility & Integration
This cable is designed exclusively for Schneider Electric's Modicon Quantum product line. It connects backplane expander modules (such as 140XBP00600 or 140XBP01000) to extend the backplane bus. The PROFIBUS connector type is physically compatible with standard PROFIBUS DP connectors, but the cable is optimized for Quantum backplane signals. Always verify that your specific Quantum backplane modules accept PROFIBUS-style connectors before ordering.
Selection Guide & Purchasing Advice
Before purchasing the 140XCA71706, confirm:
- Your system uses Modicon Quantum backplane expander modules.
- The required cable length is 2 meters – if you need a different distance, contact SpareTechPLC for alternative lengths.
- The operating environment stays within 0 °C to 60 °C and below 80% humidity (non-condensing).
