Channel Isolation and Process Interface Features
The Honeywell 51308112-005 coaxial cable set provides deterministic physical-layer connectivity across redundant LCN "A" and "B" network trunks. Engineered to suppress high-frequency electromagnetic interference, the cable construction preserves signal integrity across high-density I/O cabinets and DCS control room interfaces. The assembly operates alongside 4-20 mA HART analog communication loops and multi-channel field interface racks, maintaining low-noise transmission and robust ground potential isolation.
Frequently Asked Questions
Q: What physical connectors are terminated on the 51308112-005 LCN cable set?
A: The cable set features standard male BNC connectors designed for direct mating with Media Adapter Units (MAU) and LCN node transceiver ports.
Q: How does the cable construction prevent communication degradation in high-noise DCS environments?
A: Dual shielding along the coaxial line suppresses outer electromagnetic noise and high-frequency interference, maintaining a consistent 75-ohm impedance path for LCN token-passing traffic.
Field Installation Guidelines
Confirm that local cabinet ambient temperatures are maintained within the operating limit of -20 to 70 deg C before installing cable runs.
Inspect BNC connector interfaces to ensure pin alignment and internal locking rings are clean and undamaged.
Maintain the manufacturer-recommended minimum bend radius along the coaxial runs to prevent impedance variation or dielectric shield breakdown.
Connect BNC terminations to the LCN node ports and twist bayonet lock collars firmly to secure a low-impedance ground connection.
Verify that cable shields are properly earth-grounded at designated panel grounding bars to eliminate differential ground currents.
