Honeywell KRL-45/CM Multi-Conductor Industrial Cable

The Honeywell KRL-45/CM, also cataloged as the Honeywell KRL-45/CM Multi-Conductor Industrial Cable, operates as a dedicated hardware component for high-fidelity signal transmission and power distribution within industrial control networks. Engineered to maintain electrical loop stability under mechanical and thermal strain, this cable executes point-to-point analog and digital connections between system controllers, I/O nodes, and field instruments.

Hardware Specifications

DCS Loop & Fieldbus Integration Characteristics

• 4-20 mA HART Loop Protocol Signal Integrity: Integrates a comprehensive braided or foil shield that suppresses external electromagnetic interference (EMI), preventing voltage fluctuations from altering 4-20 mA HART analog signals.
• FOUNDATION Fieldbus / Profibus PA Segment Isolation: Engineered with high-grade heat-resistant PVC or XLPE insulation to optimize loop characteristic capacitance, preventing signal reflections and preserving data packet validity across fieldbus backbones.
• High Channel-to-Channel Isolation Support: The multi-conductor architecture with distinct color-coded configurations enables the distinct partitioning of redundant safety networks or separate analog I/O loops inside common field routing trays.

Frequently Asked Questions

Q: Can this cable be deployed in moving machinery or high-vibration applications?

A: Yes. The KRL-45/CM is constructed using stranded copper conductors and a flexible jacket architecture, providing high flexibility characteristics that make the cable suitable for dynamic installations.

Q: How should the embedded shield be terminated to maximize EMI protection?

A: The braided or foil shield must be continuous along the run and terminated to a functional earth ground bar at a single point (typically inside the marshaling cabinet) to avoid creating ground loops.

Q: What is the maximum voltage this cable can safely isolate?

A: Depending on the specific configuration and local insulation class rules, the cable supports standard system operational voltages ranging from 300 V up to 600 V.

Field Installation Guidelines

• Maintain a minimum static bend radius of 8 times the overall cable outer diameter during mounting, increasing to 12 times the outer diameter for dynamic or moving installations to prevent conductor stress.
• Apply proper wire stripping techniques to ensure the stranded copper conductors are not nicked or severed during termination, and utilize insulated wire ferrules on all connections.
• Route this low-voltage signal cable away from high-power AC motor lines and switching drives, preserving a minimum physical separation distance of 300 mm in unshielded open cable trays.
