Honeywell 51305943-100 Industrial Shielded Cable Assembly

Configured for signal integrity preservation and interference rejection in Honeywell DCS interconnect networks, the Honeywell 51305943-100 (51305943-100 Shielded Twisted Pair Cable) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation

• Channel-to-Channel Isolation: Utilizes high-density overall foil/braid shielding to isolate differential signal lines, suppressing cross-talk and preventing ground loop potential differences between connected hardware nodes.
• 4-20 mA HART Loop Protocol: Preserves low-amplitude high-frequency digital HART communication signals superimposed on 4-20 mA loops by shielding against external electromagnetic interference (EMI) and radio frequency interference (RFI).
• Cold Junction Compensation (CJC): Maintains stable low-noise signal path characteristics across low-level analog channels and remote junction termination boards operating in harsh industrial environments.

Frequently Asked Questions

Q: What insulation ratings and temperature bounds apply to the 51305943-100 cable?

A: The cable assembly features PVC conductor insulation and a rugged PVC jacket rated for 300 V isolation across an operating temperature range of -40 to 85 deg C.

Q: How does this cable protect low-level signal lines from electrical noise in industrial control cabinets?

A: It incorporates a shielded twisted-pair configuration that minimizes inductive noise coupling and blocks incoming EMI/RFI radiation across industrial environments.

Q: What conductor wire size is used inside the 51305943-100 cable assembly?

A: The cable uses 22 AWG copper conductors designed for standard terminal block connections and cable gland strain relief fittings.

Field Installation Guidelines

• Shield Drain Termination: Terminate the cable shield drain wire to the instrument earth bus at one end only to prevent circular ground currents while maintaining full EMI/RFI attenuation.
• Cable Bend Radius: Observe a minimum installation bend radius of at least 10 times the outer cable diameter during pull-through to prevent insulation deformation or shielding foil tears.
• Conduit and Tray Separation: Route shielded twisted-pair cables in dedicated low-voltage instrument trays or metallic conduits separate from high-voltage AC power and motor drive cables.
• Strain Relief Fastening: Secure the cable at terminal entry points using appropriate cable glands or strain-relief clamps to protect individual 22 AWG wire terminations from mechanical stress.
