Honeywell 51195153-900 Coaxial UCN Cable

The Honeywell 51195153-900, also cataloged as the 51195153-900 Trunk UCN A B Coaxial PLC Cable Wire, operates as a dedicated hardware component for localized high-frequency control network distribution within Universal Control Network (UCN) architectures.

Hardware Specifications

Process Control System Specifications

• FOUNDATION Fieldbus / Profibus PA Connectivity Interface Compatibility The coaxial media establishes the physical layer necessary for redundant Universal Control Network communication loops. It functions as the high-speed data highway connecting Field Control Network (FCN) nodes, Advanced Process Managers (APM), and High-Performance Process Managers (HPM) to link continuous loop data registers directly with field instrumentation data structures.
• Channel-to-Channel Isolation Performance and Radio Frequency Interference Suppression The physical shielding configuration prevents electromagnetic noise and adjacent cross-talk from corrupting token-passing communication cycles on the UCN bus. It blocks high-frequency transients and ground loop potentials from moving along the serial bus trunk, maintaining stable signal propagation across distributed plant environments.

Frequently Asked Questions

Q: How does the 51195153-900 cable interface handle data propagation across redundant UCN A and UCN B trunks?

A: The passive cabling layout transmits duplicate differential communication frames concurrently across separate physical lines. If mechanical damage or a short circuit breaks down the signal on UCN A, the system switches interface sensing to UCN B instantly without altering network update routines.

Q: Can this coaxial trunk cable be cut and terminated in the field to adapt to custom panel layouts?

A: Yes. The trunk cable is designed to be cut to size during installation. It must be terminated using matched, industrial-grade coaxial connectors and verified with a time-domain reflectometer (TDR) to confirm that impedance parameters meet network engineering standards.
