2703012

Overview

The Phoenix Contact 2703012 is a passive network isolator designed for Ethernet applications, specifically engineered for the railway industry. It provides electrical isolation to protect equipment against potential differences up to 4 kV AC. The device supports data transmission rates of 10/100 Mbps over IEEE 802.3 compliant interfaces. Connection is facilitated via two M12 D-coded female connectors. It operates without an external power supply and ensures transparent protocol support for IPv4 and IPv6.

Feature Summary

• Passive operation requiring no external power supply
• Electrical isolation protecting against potential differences up to 4 kV
• M12 D-coded connector interface for secure attachment
• Transparent protocol support for industrial networks

Applications

• Railway industry infrastructure protection
• Industrial Ethernet network segmentation
• Protection of devices with potential differences up to 4 kV

Procurement Notes

Verify the specific part number 2703012 against official Phoenix Contact documentation to confirm compatibility with your system requirements. Ensure that the M12 D-coded interface matches your existing cabling infrastructure. Confirm that the passive design meets your power budget constraints, as this unit does not require an external voltage source for operation.

Selection Notes

Select this component when electrical isolation between Ethernet segments is required without introducing active electronic components or power consumption. It is suitable for environments where potential differences between connected devices exceed safe limits. The M12 connection type makes it ideal for rugged industrial settings requiring secure, vibration-resistant connections.

Part Context

This model belongs to the FL ISOLATOR series from Phoenix Contact, which focuses on providing reliable galvanic isolation for industrial communication networks. The series is tailored for harsh environments, particularly in transportation sectors like railways, ensuring continuous operation despite electrical disturbances or ground loops between connected systems.

Replacement Considerations

Consult official Phoenix Contact substitution guides for verified equivalents. Generic isolators may lack the specific M12 D-coded interface or the certified 4 kV isolation rating required for railway compliance.
