Honeywell 51308112-015 TDC 3000 LCN Coaxial Cable
Configured for Local Control Network (LCN) communication in Honeywell TDC 3000 and Experion PKS systems, the Honeywell 51308112-015 (51308112-015 Coaxial Cable Set) provides direct physical/electrical execution. The hardware establishes deterministic serial data links across redundant A/B infrastructure paths, transferring process bus frames between network nodes without introducing impedance mismatches or propagation delay anomalies within the communication loop.

Process Control and DCS Instrumentation Technical Attributes
The cable assembly utilizes an industrial-grade RG11 shielded coaxial layer that supports high-speed data transmission over the Local Control Network bus architecture. To prevent data corruption from transient high-frequency ambient noise, the assembly integrates dedicated ferrite cores that provide continuous electromagnetic interference (EMI) and radio frequency interference (RFI) suppression.
The physical configuration directly handles the primary high-velocity communications linking TotalPlant Management System units, maintaining exact characteristic impedance profiles to eradicate signal reflections at the termination interfaces. Physical node connection loops utilize a 2-wire arrangement across independent A/B dual paths to establish media layer redundancy, safeguarding channel-to-channel isolation parameters and ensuring uninterrupted process variable updates at the distributed control system (DCS) console.
Frequently Asked Questions
Q: How do the integrated ferrite cores affect the routing footprint of the 15-meter cable set?
A: The ferrite cores are fixed directly onto the cable ends near the connectors, creating a localized rigid section that requires a larger minimum bend radius during installation to prevent core breakage or shield distortion.
Q: Can the 51308112-015 cable assembly be modified or spliced in the field to adapt to shorter control cabinet runs?
A: No, field splicing shifts the internal capacitance and characteristic impedance of the RG11 coaxial structure, which degrades signal attenuation limits and can trigger network errors on the active LCN bus.
Q: How does this assembly interact with legacy Honeywell LCN connection paths?
A: The hardware serves as a direct drop-in replacement for the older 51109181-015 cable variant, introducing upgraded noise rejection properties while matching standard physical coaxial connector interfaces.
Field Installation Guidelines
- Bending Radius Constraints: Maintain the minimum factory-specified bending radius for RG11 coaxial media during vertical and horizontal tray routing to avoid crushing the internal dielectric core.
- Shield Grounding Protocols: Secure all coaxial connector housings into the designated mating bulkheads to confirm positive grounding continuity across the overall system shield matrix.
- Physical Isolation of Redundant Pathways: Route the redundant LCN A and LCN B coaxial links through separate wire trays or conduit channels inside the enclosure to isolate the network from single-point mechanical damage.
- Ferrite Core Alignment: Position the integrated ferrite cores completely clear of sharp metallic edges or structural hinges to block mechanical stress or cracking during prolonged industrial vibrations.
