Configured for high-speed industrial Ethernet communication in Honeywell DCS and UCN platforms, the Honeywell 51305482-505 (51305482 100Base-T Ethernet Cable) provides direct physical/electrical execution.
4-20 mA Loop Immunity: Shielded twisted pair (STP) construction prevents electromagnetic coupling into neighboring analog 4-20 mA I/O signals running in adjacent cable trays.
Channel-to-Channel Shield Continuity: High-density overall braiding maintains uninterrupted ground reference continuity between distributed controller nodes and UCN network interfaces.
HART & High-Speed Data Coexistence: Maintains high-speed 100 Mbps data integrity without inducing carrier interference or high-frequency FSK noise into DCS process instrumentation loops.
Frequently Asked Questions
Q: What is the maximum data rate supported across the full 50-meter cable length?
A: The 51305482-505 cable fully supports 100 Mbps 100Base-TX Fast Ethernet standards over its entire 50-meter length without signal attenuation.
Q: How is the STP shield terminated to maintain high-frequency noise rejection in DCS cabinets?
A: The cable shield braid must be grounded via 360-degree metallic cable glands or connected to the designated chassis ground lug on the DCS module interface.
Field Installation Guidelines
Inspect cable jacket for physical abrasion prior to pulling through conduit or open-ladder wireways.
Maintain a minimum bending radius of 8 times the outer cable diameter to avoid damaging internal pair geometry and shield symmetry.
Keep signal cabling physically segregated from 480 VAC power lines in compliance with IEEE 518 installation standards.
Ensure strain relief boots are engaged at RJ45 / industrial connector terminations to prevent pin fatigue during vibration.
