Honeywell 51196074-100 EPLCG Interlink Cable

Honeywell 51196074-100 EPLCG Interlink Cable

The Honeywell 51196074-100, also cataloged as the 51196074-100 EPLCG interlink cable, serves as a shielded communication link between redundant Enhanced PLC Gateway components within Honeywell TDC 3000 and Experion PKS systems.

Hardware Specifications

FOUNDATION Fieldbus / Profibus PA Connectivity

The interlink cable supports deterministic communication across redundant Enhanced PLC Gateway (EPLCG) modules. Shielding ensures suppression of EMI/RFI interference, while the industrial-grade build maintains signal integrity in continuous-duty environments. The design allows synchronization of redundant gateways, preserving channel-to-channel isolation and ensuring uninterrupted communication paths in Honeywell DCS architectures.

Frequently Asked Questions

Q: Can the 51196074-100 cable be field-terminated? A: No, it is supplied as a factory-terminated assembly to maintain shielding integrity and connector reliability.

Q: Does the cable support redundancy switchover without signal loss? A: Yes, the cable is designed for interlink communication between redundant EPLCG modules, ensuring seamless switchover.

Q: Is the cable interchangeable with non-Honeywell interlink cables? A: No, substitution may cause impedance mismatch or communication errors; use only Honeywell-specified assemblies.

Field Installation Guidelines

• Route the cable in dedicated trays or conduits to minimize EMI exposure.
• Maintain shield grounding at a single point to avoid ground loops.
• Avoid sharp bends; follow minimum bend radius per Honeywell installation standards.
• Verify connector seating and strain relief before energizing the system.
• Keep separation from high-voltage power lines to reduce induced noise.
