1485C-P1A150 | Allen-Bradley | DeviceNet Thick Round Trunk Cable

Product Overview

The 1485C-P1A150 constitutes a high-capacity DeviceNet Thick Round Cable engineered for robust industrial communication backbones. As a primary trunk line solution, this cable supports long-distance network spans while delivering both data and power to distributed I/O modules and devices. We supply this product as a 100% Brand New 150-meter spool, ensuring factory-standard attenuation levels and jacket integrity for mission-critical automation environments.

Technical Specifications

The 1485C-P1A150 utilizes heavy-gauge conductors to maintain signal quality over extended distances:

Engineering Advantages

• Extended Network Range: The "Thick" conductor profile reduces voltage drop and signal degradation across the factory floor. This allows for significantly longer trunk line distances compared to standard "Thin" media.

• Integrated Power Distribution: This cable carries both 24V DC power and high-speed data signals simultaneously. It simplifies field installations by eliminating the need for separate power runs to remote sensors and actuators.

• Superior Mechanical Protection: The robust PVC jacket and internal shielding resist the mechanical stresses typical of industrial cable trays and conduits. This construction shields the communication pair from electromagnetic interference (EMI).

• Optimized Bulk Spooling: The 150-meter continuous spool format reduces material waste by allowing contractors to cut custom lengths for specific trunk and drop architectures.

• Environmental Resistance: The light grey PVC jacket provides excellent resistance to common industrial contaminants, ensuring long-term performance in diverse machine-level applications.

Installation & Wiring Guidelines

1. Bend Radius Compliance: Maintain the minimum specified bend radius during installation in tight conduits to prevent internal shielding fractures and impedance mismatches.

2. Termination Precision: Use high-quality DeviceNet connectors or taps. Ensure proper grounding of the drain wire at a single point to prevent ground loops that could corrupt data packets.

3. Weight Handling: Given the 70 lb spool weight, utilize a heavy-duty cable stand during payout to prevent jacket abrasions or kinks.

4. Current Limits: Observe the 4A maximum current rating. Calculate the total power consumption of all connected DeviceNet nodes to ensure the trunk line remains within thermal and electrical safety limits.

FAQs

Q: Why should I choose Thick cable over Thin cable for my DeviceNet network?

A: Thick cable like the 1485C-P1A150 features larger gauge conductors, which provide lower resistance. Choose this cable for your main trunk line to achieve longer distances and to supply more power to downstream nodes without excessive voltage drop.

Q: Does this 150m spool come with pre-attached connectors?

A: No. This is a 100% Brand New bulk spool of raw cable. This format allows for custom-length installations and requires field-attachable connectors or terminal block wiring.

Q: Can this cable be used in outdoor or direct burial applications?

A: This cable features a standard industrial PVC jacket designed for indoor use in trays, conduits, and panels. For outdoor or high-moisture environments, verify local code requirements regarding additional conduit protection.

Q: Is the light grey color indicative of any specific rating?

A: The light grey color follows the standard industrial aesthetic for DeviceNet media, facilitating easy identification within complex cable bundles and ensuring aesthetic consistency with other Allen-Bradley 1485C components.
