Description

The Siemens 6ES5711-0AD20 is a specialized vertical rail-to-rail cable connector designed for the Siemens Simatic S5-110 modular automation system. This 0.23-meter interconnect is engineered to bridge signal lines between vertically adjacent mounting rails, ensuring continuous internal bus communication across split-tier control panel configurations. It is a critical component for expanding system capacity in legacy S5-110 installations, providing a reliable, low-impedance path for time-critical control signals.

Features

• Designed specifically for Siemens Simatic S5-110 modular frameworks.
• Facilitates seamless vertical rail-to-rail signal bridging.
• 0.23-meter length optimized for compact control enclosure layouts.
• Heavy-duty insulation protects logic paths from industrial vibration and thermal stress.
• Positive-locking pin headers ensure secure connection to backplane extension receptacles.
• Maintains predictable bus scan rates by preventing impedance mismatch.

Applications

This cable connector is widely utilized in legacy industrial automation environments, including power generation stations, metal processing facilities, and bulk material handling systems. It is essential for field engineers performing system expansions or maintenance on S5-110 racks where vertical rail connectivity is required.

Technical Specifications

Installation Guidelines

• Ensure the PLC system is fully powered down before connecting or disconnecting any bus cables to prevent electrical damage to backplane components.
• Inspect pin headers for debris or bent pins prior to insertion into the chassis receptacles.
• Route the cable to avoid sharp bends or proximity to high-voltage power lines to minimize EMI interference.
• Ensure the connector is fully seated and the locking mechanism is engaged to prevent signal intermittent loss due to vibration.
• Verify bus continuity after installation before restoring full system operation.

FAQ

Is this cable compatible with other Siemens S5 series?

This specific model is designed for the S5-110 series. Please verify your specific backplane receptacle type before installation, as compatibility with other S5 families (such as S5-115U or S5-155U) is not guaranteed.

Does this cable require external power?

No, the 6ES5711-0AD20 is a passive signal routing cable and does not require external power or configuration.
