1756-RMC1 | Allen-Bradley Fiber Optic Cable Supplier

Introduction to the 1756-RMC1 Fiber Optic Cable

When building a ControlLogix redundant controller system, reliable communication between redundancy modules is essential. The 1756-RMC1 from Allen-Bradley provides a dedicated fiber optic connection for this purpose. Part of the ControlLogix series, this cable is designed specifically for use with the 1756-RM2 and 1756-RM2K redundancy modules. It is the shortest cable available for these modules, measuring 3.28 feet (1 meter).

Key Features and Technical Specifications

• Manufactured by Rockwell Automation under the Allen-Bradley brand.
• Part number 1756-RMC1, part of the ControlLogix series.
• Module type: Fiber Optic Cable with a length of 3.28 feet (1 meter).
• Wavelength of 1300 Newton Meters and transmission speed less than 1000 MB-Second.
• Single channel cable with an operating temperature range of 32-140 Fahrenheit (0-60 Celsius).
• Wire size is 20 AWG, and dimensions are 5.51 x 4.41 x 5.71 inches.
• Enclosure type: None.

The distinctive spec here is the 1300 Newton Meters wavelength, which ensures reliable optical signal transmission over the short distance required for redundancy module linking.

Applications and Use Cases

The 1756-RMC1 is essential for ControlLogix redundant controller systems. For example, in a manufacturing plant where uptime is critical, this cable connects the primary and backup controllers, allowing seamless failover. It is compatible with both standard and extreme-environment modules, making it suitable for harsh industrial settings. Additionally, the cable's single channel design supports a straightforward redundant architecture.

Installation and Setup Guide

To install the 1756-RMC1, first remove the protective caps from the connectors. Connect the cable at the bottom of the redundancy module in a downward orientation. Avoid sharp bends in the cable, as it contains optical fibers. Use the LC connector coupler to prevent bending and to allow easy connection and disconnection without removing the module from the chassis. Ensure the cable path is not prone to being run over, abraded, cut, or otherwise damaged.

Maintenance and Reliability Tips

Regularly inspect the 1756-RMC1 for physical damage, especially at the connectors and along the cable length. Keep the operating environment within the specified temperature range of 0-60 Celsius to maintain signal integrity. Because the cable is used in redundant systems, periodic verification of both channels helps ensure system reliability. Follow the manufacturer's manual for detailed maintenance procedures.

Compatibility and Integration

The 1756-RMC1 is designed for use with Allen-Bradley ControlLogix 1756-RM2 and 1756-RM2K redundancy modules. It is part of the Bulletin 1756-RMCx Cable Series, which offers various lengths. This cable is required for building a ControlLogix redundant controller system; one or two cables may be needed. Note that redundancy modules and chassis do not ship with these connectors, so order them separately before system assembly.
