Honeywell 51308112-010 LCN RG11 Coaxial Cable Assembly

Product Description

The Honeywell 51308112-010 is a factory-terminated Local Control Network (LCN) coaxial cable assembly engineered for deterministic data transmission in Honeywell distributed control systems. Built on an RG11 coaxial platform and enhanced with integrated ferrite suppression, this cable is designed to maintain signal integrity in electrically noisy control-room and plant-floor environments.

This cable assembly is primarily deployed as a backbone or inter-cabinet connection within Honeywell LCN architectures, where impedance stability, shielding effectiveness, and long-term reliability are critical.

The 51308112-010 replaces earlier non-ferrite variants and reflects Honeywell’s updated design approach for improved electromagnetic compatibility in modern installations.

Technical Specifications

Key Technical Characteristics

The Honeywell 51308112-010 is designed to meet the electrical and mechanical requirements of Honeywell’s proprietary LCN architecture. Its RG11 coaxial construction ensures consistent characteristic impedance, while the added ferrite elements suppress high-frequency noise and transient interference.

Compared to legacy LCN cables without ferrite filtering, this version offers improved resistance to electromagnetic disturbances caused by power switching equipment, drives, and adjacent communication lines.

The cable is intended for fixed installation and long service life, minimizing the risk of intermittent communication faults that can affect system availability.

System Compatibility and Applications

The 51308112-010 is qualified for use in Honeywell control platforms that utilize LCN communication, including:

Honeywell TDC 3000 systems Honeywell Experion PKS architectures Honeywell TPS and legacy LCN-based systems

Typical application points include controller-to-controller links, LCN node interconnections, and structured control-room network layouts.

Replacement and Model Comparison

This cable assembly supersedes Honeywell 51109181-010, which used the same RG11 coaxial base but did not include ferrite noise suppression.

Key differences include enhanced EMI resilience, improved signal stability in mixed-signal environments, and alignment with current Honeywell installation recommendations.

Frequently Asked Questions

Q: Is the 51308112-010 backward compatible with older LCN systems? Yes. The cable maintains the same electrical characteristics as earlier RG11 LCN cables and can be used as a direct replacement.

Q: Why are ferrites integrated into this cable assembly? Ferrites reduce high-frequency interference and common-mode noise, improving communication reliability in electrically dense control environments.

Q: Can this cable be field-modified or cut to length? No. The cable is factory-terminated and certified; field modification is not recommended and may affect LCN performance.
