Honeywell 3400288 Industrial Control Series

The Honeywell 3400288, also cataloged as the Honeywell 3400288 Industrial Control Cable, operates as a dedicated hardware component for high-fidelity physical signal transmission within Honeywell TDC 3000, Experion PKS, and distributed control system (DCS) networks. Configured to preserve loop integrity under rigorous mechanical, thermal, and electrical stressors, it executes continuous point-to-point analog and digital signaling without signal distortion.

Hardware Specifications

DCS Loop & Fieldbus Integration Characteristics

• 4-20 mA HART Loop Protocol Compatibility: Features balanced impedance matching to support simultaneous analog signaling and high-frequency digital HART frequency-shift keying (FSK) communication without signal attenuation or phase distortion.
• FOUNDATION Fieldbus & Profibus PA Physical Layer Compliance: Meets nominal impedance, attenuation limits, and capacitive imbalance parameters required by IEC 61158-2 standards to avoid reflections and signal degradation on high-speed fieldbus networks.
• High Channel-to-Channel Isolation Support: Designed to supplement the isolated inputs of DCS modules, preventing ground loops and cross-talk when routed through multi-channel non-isolated field terminal assemblies (FTAs).

Frequently Asked Questions

Q: Can this cable operate outdoors and in direct exposure to sunlight?

A: Yes. The polyurethane insulation formula is chemically structured to withstand direct ultraviolet (UV) radiation, atmospheric moisture, and typical industrial hydrocarbon exposure without structural degradation or loss of dielectric strength.

Q: How should the drain wire and shielding be grounded during installation?

A: In compliance with standard DCS grounding practices, the shield and tinned copper drain wire must be grounded at one single point (typically the cabinet ground bar at the DCS end) to avoid ground loops. The field-device end must remain ungrounded and properly insulated with shrinkable tubing.

Q: What is the maximum physical tensile force limit of the 22 AWG conductors?

A: The premium copper alloy 22 AWG conductor design supports a maximum pulling tension of 110 N (approximately 25 lbs) during routing. Exceeding this mechanical threshold risks structural elongation of conductors and variations in characteristic loop impedance.

Field Installation Guidelines

• Maintain a minimum bend radius of 8 times the overall cable outer diameter (approximately 50 mm) during installation to protect conductor geometry and foil shield integrity.
• Avoid running this low-voltage signal cable parallel to high-voltage, high-current AC power cables. Maintain a minimum separation distance of 300 mm in open cable trays or separate conduit systems to minimize inductive noise injection.
• Ensure all mechanical cable entries into terminal junction boxes utilize approved industrial compression-style liquid-tight cable glands to maintain system IP/NEMA enclosure ratings.
