Honeywell 51195199-005 TDC 3000 Coaxial Drop Cable Assembly

The Honeywell 51195199-005, operates as a dedicated hardware component for high-frequency serial network communication within Honeywell TDC 3000 Universal Control Network (UCN) architectures.

Hardware Specifications

Process Control and Network Architecture

• Backplane Bus Communication Velocity: The cable assembly routes serialized field data between localized process managers and the 5 Mbps token-passing Universal Control Network (UCN) backbone. This dedicated media line maintains deterministic transmission velocities, eliminating signal propagation skew to support precise sub-millisecond control loop execution.
• I/O Density Scaling: The 5 m physical length allows for flexible vertical or horizontal separation of high-density I/O card files from the main network tap boxes. This architecture enables concentrated multi-channel data aggregation within a single cabinet footprint without introducing signal attenuation or dropouts across the 75 Ohm communication line.
• Firmware Flash Compatibility: Being a passive physical layer conductor, the cable requires no internal flash microcode or configuration software. However, it interfaces directly with intelligent communication processors whose internal transceiver firmware and node address assignments must match the system baseline to guarantee correct slot identification during cold boot sequences.

Frequently Asked Questions

Q: What are the engineering consequences of exceeding the minimum bend radius of this 5 m coaxial drop cable during installation?

A: Bending the cable beyond its physical threshold deforms the internal dielectric core spacing between the center conductor and the outer shield. This geometric alteration causes a localized shift in characteristic impedance away from 75 Ohms, producing high-frequency signal reflections that manifest as CRC frame errors or packet drops on the active UCN bus.

Q: Can this cable assembly be spliced or extended in the field if the 5 m length is insufficient?

A: No. Field splicing of the 51195199-005 coaxial assembly is strictly prohibited. Modifying the factory-terminated line introduces impedance discontinuities and attenuation nodes that degrade the high-frequency 5 Mbps data signal, compromising the noise immunity margins of the entire network segment.
