Honeywell 51201817-100 Control Cable Assembly

Configured for low-voltage signal transmission in Honeywell Distributed Control Systems, the Honeywell 51201817-100 (51201817 Control Cable Assembly) provides direct physical/electrical execution.

Hardware Specifications

DCS Communication & Loop Integrity

• HART Signal Stabilization: Utilizes physical shielding pathways to preserve the 4-20 mA HART loop protocol signal profile against electromagnetic degradation in cabinet-to-cabinet transfers.
• Logical Channel-to-Channel Isolation: The layout is engineered to support the isolated routing of instrumentation channels, maintaining physical and inductive separation between independent control loops and prevents signal crosstalk.

Frequently Asked Questions

Q: Does this cable support hot-swap installation of active DCS cards?

A: Yes. As a passive, shielded cable interface, it does not restrict the online removal or insertion of hot-swapping modules, provided the associated Honeywell I/O chassis supports hot-swap procedures.

Q: Can this cable be run in the same cable tray as AC power feeds?

A: No. To comply with DCS signal integrity protocols, low-voltage control cables must be segregated into dedicated conduits or partitioned cable trays separate from high-voltage AC lines.

Field Installation Guidelines

• Static Bend Radius: Maintain a static bend radius of at least 10 times the outer cable diameter to protect the inner low-resistance copper conductors and shielded layers.
• Single-Ended Shield Grounding: Terminate the cable drain shield at one designated ground terminal (usually inside the marshalling cabinet) to prevent loop currents.
• Connector Seating Verification: Ensure all multi-pin module connectors are fully seated and locked to prevent high-resistance connection faults caused by industrial vibration.
