Allen-Bradley 1747-C13 SLC 500 DH-485 Operating System Programming Cable

Product Overview

The Allen-Bradley 1747-C13 serves as a specialized interconnect cable for the SLC 500 modular hardware platform. This 3-foot (0.9 meter) cable facilitates the physical link between an SLC 500 processor (via the RJ45 port) and a 1747-PIC Personal Computer Interface Converter or a 1747-UIC USB-to-DH-485 interface. It enables critical functions such as program uploads, downloads, and real-time data monitoring over the DH-485 network. We provide this cable as 100% Brand New original stock to ensure error-free data transmission and a secure mechanical fit.

Technical Specifications

The 1747-C13 meets the specific electrical requirements for DH-485 signaling:

Engineering Advantages

• Shielded Signal Integrity: The 1747-C13 utilizes high-quality shielding to protect data packets from electromagnetic interference (EMI) commonly found in industrial environments. This shielding prevents communication timeouts and checksum errors during critical firmware or program transfers.

• Precision RJ45 Termination: The factory-molded RJ45 connectors ensure a tight, low-resistance connection with the processor port. This eliminates the intermittent connectivity issues often associated with generic or hand-crimped network cables.

• Optimized for Portability: The 3-foot length provides the ideal span for connecting a laptop or interface box to a PLC rack within a control cabinet. This keeps the workspace organized and minimizes the risk of cable snagging during maintenance.

• Standardized Pinout: Using a Brand New 1747-C13 guarantees the correct proprietary pinout required by Allen-Bradley hardware. This prevents the potential short-circuits or hardware damage that can occur when using standard Ethernet patch cables in DH-485 ports.

FAQs

• Q: Can I use a standard Ethernet cable instead of the 1747-C13?

• A: No. While the connectors look identical to RJ45 Ethernet, the pinout and electrical signals for DH-485 differ significantly. Using a standard Ethernet cable can damage the processor's communication port.

• Q: Does this cable connect directly to a PC's serial port?

• A: No. The 1747-C13 must connect to a converter, such as the 1747-UIC (USB) or the 1747-PIC (Serial), which then interfaces with your computer.

• Q: Is this cable compatible with the SLC 5/04 or 5/05 processors?

• A: While the 1747-C13 can physically plug into the DH-485 port of a 5/03, it is primarily used for the SLC 5/01 and 5/02. The SLC 5/05 uses standard Ethernet (RJ45), but for its specific communication protocols, always refer to the hardware manual.

• Q: Why is "Brand New" quality important for a simple cable?

• A: Used cables often suffer from weakened internal copper strands or worn locking tabs. A 100% Brand New 1747-C13 ensures the locking clip stays secure and the internal resistance remains within factory tolerances for stable communication.
