Honeywell MU-NKT050 51195199-050 50-Meter UCN Trunk Interface Cable

Technical Product Overview

The MU-NKT050 (51195199-050) is a high-integrity 50-meter Universal Control Network (UCN) trunk cable designed for the foundational communication layer of Honeywell TDC 3000 and Experion PKS systems. This specialized coaxial cable serves as the primary data highway, connecting High-Performance Process Managers (HPM), Network Interface Modules (NIM), and other UCN-based controllers across the plant floor.

Engineered to meet the rigorous demands of industrial data transmission, the MU-NKT050 (51195199-050) features advanced shielding to maintain signal purity over its 50-meter span. This cable is critical for ensuring low-latency, deterministic communication between the DCS controllers and the supervisory network, preventing data packet loss in high-interference environments.

Network Integration and Reliability

The MU-NKT050 (51195199-050) is vital for maintaining the "Always-On" requirement of a Distributed Control System. Its 50-meter length is factory-tested to ensure that the physical layer timing constants remain within the strict tolerances required by the UCN token-passing protocol. Using factory-certified cabling like the MU-NKT050 (51195199-050) minimizes the risk of standing wave interference and reflections that commonly occur with poor-quality or field-spliced coaxial lines.

Frequently Asked Questions

Can the MU-NKT050 (51195199-050) be shortened in the field?

While coaxial cable can technically be cut, it is highly recommended to use the factory-certified MU-NKT050 (51195199-050) length. Field-terminating UCN trunk cables requires specialized tools and testing to ensure the decibel loss remains within Honeywell's certified limits.

Is this cable suitable for burial?

This cable is typically designed for installation in cable trays, raceways, or conduits. For direct burial applications, additional mechanical protection or a specific "DB" rated jacket variant should be confirmed.
