Honeywell 51195153-002 Coaxial Set – High-Integrity Signal Cable Assembly | TDC 3000 DCS Platform
Engineering Background
The Honeywell TDC 3000 (Total Distributed Control) platform has been the backbone of process automation in refining, petrochemical, and power generation facilities for decades. Reliable inter-module communication depends critically on the integrity of coaxial cable assemblies. The 51195153-002 Coaxial Set is the OEM-specified cable assembly designed to maintain signal fidelity across the Local Control Network (LCN) and Highway backplane interconnects within TDC 3000 cabinets.
Product Positioning
This coaxial set is a direct-replacement, factory-grade cable assembly for maintenance, cabinet rebuild, and system expansion projects. It is sourced from authorized Honeywell distribution channels and verified against OEM specifications before shipment. Procurement engineers specify this part to eliminate signal degradation, ground loop interference, and intermittent communication faults that arise from aged or non-OEM cables.

Engineering Advantages
- OEM-matched impedance: Eliminates reflections and signal attenuation on the LCN Highway that cause intermittent node dropouts.
- Factory-terminated connectors: Precision crimp/solder terminations maintain VSWR within TDC 3000 specification — no field-termination variability.
- Flame-retardant jacket: Complies with cabinet fire-safety requirements in classified process areas.
- Drop-in replacement: Identical form, fit, and function to original Honeywell BOM — no re-engineering or re-qualification required.
- Traceable provenance: Each unit ships with documentation supporting maintenance records and ISO 9001 audit trails.
System Architecture & Signal Flow
Within the TDC 3000 architecture, the Local Control Network (LCN) is a 5 Mbit/s token-passing coaxial highway connecting Application Modules (AM), History Modules (HM), Universal Stations (US), and Network Interface Modules (NIM). The 51195153-002 Coaxial Set provides the physical-layer segment between cabinet backplane tap points and the LCN trunk cable, ensuring the 75 Ω characteristic impedance is maintained end-to-end. Impedance discontinuities as small as ±5 Ω can cause reflected signals that degrade network throughput and trigger spurious node resets — making OEM cable assemblies non-negotiable for mission-critical installations.
Sourcing & Quality Verification

Technical FAQ
Q: Is 51195153-002 compatible with both TDC 3000 and TPS (TotalPlant Solution) systems?
A: Yes. TPS is the evolutionary successor to TDC 3000 and retains LCN coaxial infrastructure. This cable set is compatible with both generations.
Q: Can I substitute a generic 75 Ω RG-59 cable?
A: Not recommended. The OEM assembly uses specific connector termination geometry and cable capacitance values optimized for the LCN token-passing protocol. Generic substitutes introduce impedance discontinuities and may void Honeywell system support agreements.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For larger quantities, lead time is confirmed at quotation stage.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A CoC and inspection report are available upon request for all shipments.
