Honeywell 51196742-200 Industrial Video Cable Assembly

The Honeywell 51196742-200, also cataloged as the 51196742-200 Industrial Video Cable Assembly, operates as a dedicated hardware component for stable video signal transmission between video-enabled modules, displays, and diagnostic hardware within Experion PKS and C300 control system architectures.

Hardware Specifications

Process Control and DCS Instrumentation Characteristics

• 4-20 mA HART loop protocol: Although this assembly is designated for video transmission, it is designed for integration within the broader Experion PKS cabinet architecture. The shielding and termination geometry are engineered to prevent inductive crosstalk when routed through cable trays alongside signal-critical HART-enabled analog loops.

• Channel-to-channel isolation: The multi-layer shielded architecture provides robust electrical isolation for high-frequency video signals. This design ensures that the high-bandwidth requirements of the video link do not generate electromagnetic noise that could interfere with nearby low-voltage I/O modules.

• Cold junction compensation (CJC): In cabinets where this video assembly is co-located with thermocouple termination assemblies, the shielding effectiveness prevents localized thermal gradients that could otherwise influence CJC stability in surrounding process control modules.

• FOUNDATION Fieldbus / Profibus PA connectivity: The assembly’s characteristic impedance is optimized for signal fidelity in Honeywell control environments. This ensures that the video signal path maintains the required bandwidth for diagnostic visualization without inducing signal reflections that could disrupt the underlying Fieldbus network stability.

Frequently Asked Questions

Q: Can this cable assembly be used to replace standard commercial VGA or DVI cables?

A: No. The 51196742-200 is engineered to Honeywell-specific electrical and mechanical pinout standards. Substitution with standard commercial cables will result in signal loss or potential hardware damage to the interface ports.

Q: Is this assembly intended for long-distance runs between different control rooms?

A: No. This cable is optimized for intra-cabinet or control room console routing. For long-distance visualization links, consider utilizing specialized Honeywell-certified optical converters or signal boosters to maintain image quality and timing synchronization.

Field Installation Guidelines

• Mounting: Support the cable using industrial-grade cable ties at 300 mm intervals to prevent connector strain. Ensure the cable is not subjected to excessive tension or sharp-angle bending, as mechanical stress can fracture the internal shielding and degrade high-frequency image stability.

• Grounding: Secure the connector’s metal housing to the chassis ground of the interface module. A low-impedance bond is necessary to ensure the cable’s shield effectively drains high-frequency noise to the cabinet earth bus.

• Wiring: Maintain a physical separation of at least 150 mm from high-current power cables and VFD motor leads. When crossing high-voltage paths, ensure a 90-degree intersection to minimize inductive noise coupling into the video signal conductors.
