Honeywell 51308111-002 LCN Coax Cable Set

Overview

The Honeywell 51308111-002, also cataloged as the 51308111-002 LCN Coax Cable Set, operates as a dedicated hardware component for coaxial data transmission within Honeywell TDC 3000 and Experion PKS LCN network platforms.

Hardware Specifications

LCN Network Signal Transmission Characteristics

The Honeywell 51308111-002 provides physical coaxial connectivity between LCN nodes, processors, and communication interface assemblies. It transfers network signals through a shielded cable structure, while the outer conductive layer reduces electromagnetic interference during operation.

In addition, the factory-terminated connector design maintains controlled impedance and reduces signal degradation caused by field splicing. The cable assembly supports standard LCN communication practices used in Honeywell process control architectures.

Frequently Asked Questions

Q: Does the Honeywell 51308111-002 require external power input?
A: No. The 51308111-002 is a passive coaxial cable assembly and does not consume electrical power during signal transmission.

Q: Can the cable length or connector type be modified in the field?
A: Field modification is not recommended because cutting, extending, or replacing factory-installed connectors can affect impedance matching and network signal quality.

Q: What installation practice applies to the cable shielding?
A: The cable shield should maintain proper grounding practices according to the Honeywell system cabinet and LCN installation requirements to minimize electromagnetic interference.

Field Installation Guidelines

1. Install the 51308111-002 between designated LCN communication ports without excessive bending or mechanical stress on the coaxial cable.
2. Verify connector seating before system startup. Loose coaxial connections may introduce signal attenuation or intermittent communication faults.
3. Route the cable separately from high-voltage power wiring, motor supply cables, and strong electromagnetic noise sources.
4. Maintain the factory cable termination and shielding structure. Do not remove the outer shield or perform unauthorized cable repairs.
5. Confirm the connected Honeywell node addresses and LCN network configuration before returning the control system to operation.
