Allen-Bradley 1756-CP3 ControlLogix PLC Programming Cable

Product Overview

The 1756-CP3 serves as the primary physical communication link between a workstation and the Allen-Bradley ControlLogix controller family. This high-quality RS-232 programming cable facilitates seamless logic uploads, downloads, and real-time monitoring. We provide this unit as 100% Brand New in original packaging to ensure peak signal integrity and connection longevity in demanding factory environments.

Technical Specifications

Engineering Advantages

• Optimized Spatial Efficiency: The 90-degree female D-shell connector reduces the physical footprint at the controller interface. This right-angle design prevents cable strain and allows cabinet doors to close securely in shallow enclosures.

• Industrial-Grade Shielding: The cable construction resists electromagnetic interference (EMI), ensuring stable data transmission even when routed near high-voltage motor leads or switching gear.

• Extended Reach: The 3-meter length provides ample flexibility for engineers to position laptops safely outside the immediate "arc flash" zone or crowded terminal areas during live diagnostics.

• Plug-and-Play Integration: Standardized 9-pin configurations eliminate the need for custom pinout adapters, reducing setup time during critical commissioning phases.

FAQs

Does this cable support 100% original factory protocols? Yes. This 1756-CP3 is a brand-new, high-standard component that maintains full compatibility with RSLinx Classic and Studio 5000 software suites for all ControlLogix processors equipped with a serial port.

Can I use the 1756-CP3 for permanent HMIs or only for programming? While primarily designed for programming and configuration, the 1756-CP3 supports continuous RS-232 serial communication between the PLC and compatible HMI hardware or peripheral devices.

What is the advantage of the 90-degree connector over a straight one? The 90-degree connector specifically targets high-density racks. It directs the cable downward or sideways, preventing the connector from protruding too far and risking mechanical damage from accidental contact or enclosure door pressure.
