Honeywell 51305478-100 DCS Control Cable

Configured for analog and digital signal interconnects in Honeywell TDC 3000 and Experion PKS platforms, the Honeywell 51305478-100 (51305478 Industrial Control & Signal Cable) provides direct physical/electrical execution.

Hardware Specifications

DCS Interconnect & Signal Shielding Characteristics

• HART Loop Signal Preservation: Low internal conductor capacitance preserves 4-20 mA HART frequency-shift keying (FSK) digital modulation waveforms across extended field cable runs without signal degradation.
• Dual-Layer EMI/RFI Mitigation: Combination of aluminum-mylar foil and high-density tinned copper braid prevents external electromagnetic noise coupling into sensitive DCS analog input channels.
• DCS I/O Termination Compatibility: Stranded tinned copper conductors match standard Honeywell Experion PKS terminal blocks, preventing contact resistance growth caused by conductor oxidation.

Frequently Asked Questions

Q: What is the recommended grounding practice for the overall cable shield in 4-20 mA DCS loops?

A: The overall foil and braided shield must be grounded at a single point, typically at the DCS cabinet ground bar, to eliminate ground loop currents while maintaining high-frequency noise attenuation.

Q: Can the 51305478-100 cable be routed alongside 480 VAC motor power cables in the same cable tray?

A: No, low-level signal cables must maintain physical separation from AC power lines in accordance with IEEE 518 guidance to avoid magnetic inductive coupling.

Field Installation Guidelines

1. Strip outer jacket carefully using calibrated tools to avoid scoring the braid shield or internal conductor insulation.
2. Ensure the drain wire and braid shield are terminated cleanly with insulated sleeving to prevent unintended contact with the enclosure chassis or adjacent terminal points.
3. Maintain a minimum bending radius of 10 times the outer cable diameter during tray laying and conduit pull operations.
4. Apply approved cable gland fittings when entering hazardous area enclosures to maintain IP rating and explosion-proof integrity.
