Product Introduction

The Allen Bradley 1747-C13 SLC 500 Communication Cable is a dedicated connection accessory for compatible Allen Bradley SLC 500 automation systems. It is designed to connect specialty modules, including BASIC and KE modules, to the 1747-AIC Isolated Link Coupler.

The cable supports communication within a DH-485 network, making it relevant to legacy PLC installations that rely on this communication architecture. Its 3-foot (0.91 m) length is suitable for connections between nearby control components.

An important technical distinction is that the 1747-C13 carries communication signals only; it does not provide 24 VDC power to the 1747-AIC. The power connection must be arranged separately using the appropriate cable or external power source specified for the installation.

For maintenance and replacement projects, selecting the correct cable is essential because SLC 500 accessories such as the 1747-C10, 1747-C11, and 1747-C13 serve different connection purposes. Checking the module catalog numbers and wiring arrangement before installation helps prevent communication problems and incorrect connections.

Typical applications include:

DH-485 Network Communication: Establishes a communication connection between compatible SLC 500 modules and network interface equipment.
BASIC Module Connectivity: Connects an SLC 500 BASIC or BASIC-T module to a 1747-AIC Isolated Link Coupler.
KE Module Communication: Supports communication connections involving compatible 1747-KE interface modules.
PLC Maintenance: Provides a replacement cable for servicing existing SLC 500 communication installations.
Legacy Automation Systems: Helps maintain communication infrastructure in facilities operating older Allen Bradley PLC equipment.

Key Features and Advantages

Dedicated SLC 500 Compatibility: Designed for specific communication arrangements within the Allen Bradley SLC 500 platform.

DH-485 Communication Support: Provides the physical communication link required for compatible specialty modules and isolated link couplers.

Compact Cable Length: The 3-foot (0.91 m) length is suitable for connections between nearby modules and communication interfaces.

Communication-Only Function: Carries communication signals rather than supplying 24 VDC power to the isolated link coupler.

Convenient Replacement: Offers a catalog-number-specific replacement option for maintaining existing SLC 500 installations.

Technical FAQs

Q1: What is the primary function of the 1747-C13?

A: It provides a communication connection between compatible SLC 500 specialty modules, such as BASIC or KE modules, and a 1747-AIC Isolated Link Coupler.

Q2: What communication network is supported?

A: The cable is used in DH-485 communication arrangements within compatible SLC 500 systems.

Q3: What is the cable length?

A: The specified cable length is 3 feet, approximately 0.91 meters.

Q4: Does the 1747-C13 supply 24 VDC power to the 1747-AIC?

A: No. The 1747-C13 functions as a communication link and does not carry 24 VDC power. A separate appropriate power connection is required.

Q5: Can the 1747-C13 connect a BASIC module to a 1747-AIC?

A: Yes. This is one of its documented applications in an SLC 500 system.

Q6: Is the 1747-C13 interchangeable with the 1747-C10?

A: No. The 1747-C13 provides the communication connection, while the 1747-C10 is used for a different processor-to-peripheral connection and can supply power to the isolated link coupler in the relevant arrangement.

Q7: What is the difference between the 1747-C13 and 1747-C11?

A: The 1747-C13 is a specialty-module-to-isolated-link-coupler communication cable. The 1747-C11 is a processor-to-isolated-link-coupler replacement cable. Their connection functions differ.

Q8: Can the 1747-C13 be used with a 1747-UIC interface?

A: The cable is listed for compatible 1747-UIC communication arrangements. Confirm the port connection and intended network configuration before installation.

Q9: What should be checked if communication fails?

A: Inspect the cable and connectors, verify the correct port connections, check the 1747-AIC power supply, and confirm that the DH-485 network configuration is correct.

Q10: Can a standard Ethernet patch cable replace the 1747-C13?

A: No. Similar connector shapes do not guarantee compatible wiring or electrical characteristics. Use the specified cable or a verified equivalent.
