Honeywell 51195153-900 UCN Drop Cable Set

The Honeywell 51195153-900, also cataloged as the 51195153 UCN Drop Cable Set, operates as a dedicated hardware component for high-frequency signal transmission within Universal Control Network (UCN) platforms.

Hardware Specifications

Process Control Integration & Cable Shielding

The 51195153-900 drop cable set is deployed to connect nodes within legacy and modern Honeywell architectures, integrating physical-layer signal protections:

• 4-20 mA HART Loop Shielding: The continuous overall metallic shielding of the RG6 coaxial assembly blocks high-frequency electromagnetic interference (EMI), ensuring nearby analog 4-20 mA HART loops are shielded from control network carrier frequencies.
• Channel-to-Channel Isolation Support: Grounding the drop cable shields at the dedicated TAP connectors prevents common-mode voltage spikes from entering the network, preserving the channel-to-channel isolation of connected nodes.
• FOUNDATION Fieldbus / Profibus PA Co-existence: The physical separation and high-rejection dielectric shielding design minimize radio-frequency cross-talk when run near digital fieldbus segments.

Frequently Asked Questions

Q: Can this drop cable set be shortened or extended in the field?

A: No. The 51195153-900 is factory-terminated to maintain exact signal attenuation and reflection limits. Splicing or manually installing alternative connectors will disrupt the impedance match and can cause critical communication losses on the UCN.

Q: What specific hardware does this cable connect?

A: This drop cable set links standard system modules directly to the UCN trunk line via tap units, facilitating reliable high-speed network communication across nodes.

Field Installation Guidelines

• Route Separation: Segregate the coaxial drop cable from high-voltage AC cables and variable-frequency drive motor leads, keeping a minimum distance of 300 mm to suppress noise induction.
• Bend Radius Limits: Maintain a minimum bend radius of ten times the cable outer diameter during mounting to prevent crimping the internal dielectric layer and changing cable impedance.
• Connector Protection: Protect the factory-installed connectors from dirt, oil, and moisture contamination during installation. Threaded terminations must be securely tightened to ensure continuous shield grounding.
• Physical Protection: Run cables within industrial conduits or trays where physical damage or sharp mechanical edges could sever the external protective jacket.
