Product Details

Product Overview

The 1746-C7 serves as a critical hardware bridge within the SLC 500 modular controller system. This high-density interconnect cable facilitates seamless backplane communication between two local chassis. Engineered for reliability in industrial environments, the 1746-C7 (PN: 1746-C7) ensures that the processor can address I/O modules across extended rack configurations without signal degradation.

Technical Specifications

  • Manufacturer Allen-Bradley / Rockwell Automation

  • Hardware Category PLC Chassis Components

  • Product Series SLC 500 Modular Hardware

  • Model Number 1746-C7

  • Primary Function Backplane Interconnect (Chassis-to-Chassis)

  • Physical Length 0.5 feet (0.15 meters / 6 inches)

  • Slot Requirement Occupies 1 slot on each connected chassis

  • Current Draw at 5V DC 110 mA

  • Current Draw at 24V DC 85 mA

  • Shipping Weight 0.13 lbs (0.06 kg)

Application and Installation

The 1746-C7 is specifically designed for side-by-side chassis mounting. Because the cable length is fixed at 6 inches, it provides the lowest possible impedance for high-speed data transfer between the CPU chassis and the expansion chassis. For vertical mounting or wider spacing, engineers should consider longer variants like the 1746-C9.

Frequently Asked Questions

  • Does the 1746-C7 require a separate power supply?

    No, the cable draws its operating current (110mA @ 5V / 85mA @ 24V) directly from the SLC backplane power supply.

  • Can I hot-swap this cable while the PLC is running?

    It is strongly recommended to remove all system power before installing or removing the 1746-C7 to prevent backplane shorts or data corruption.

  • Is the 1746-C7 shielded?

    Yes, it features industrial-grade shielding to protect the sensitive backplane bus signals from electromagnetic interference (EMI) typical in factory environments.
