Allen-Bradley 1794-CE3 Flex I/O Extender Cable for System Layout Flexibility

Product Introduction

When space constraints force you to rethink your I/O layout, the Allen-Bradley 1794-CE3 Flex I/O extender cable provides a practical solution. This 3-foot interconnect cable allows you to split a Flex I/O 1794 system into two smaller rows instead of one long row, enabling flexible mounting on DIN rail, panels, or walls. Designed for in-cabinet use, it operates reliably in temperatures from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).

Technical Specifications Breakdown

The 1794-CE3 is a dedicated extended-local I/O cable from the Flex I/O 1794 series. Its key specifications include a length of 3 feet (0.9 meters) and a weight of 0.44 lbs (0.20 kg). The cable features an open enclosure type and supports DIN rail and panel mounting. It is the only interconnect cable required in a Flex I/O 1794 system, simplifying installation and reducing potential failure points.

Industry Applications

In manufacturing environments where machine footprints are shrinking, the 1794-CE3 enables engineers to arrange I/O modules in two rows or split them into vertical and horizontal alignments. This is especially useful in crowded control cabinets where a single long row of modules would not fit. The cable also connects the 1794-FLA adapter to a FlexLogix controller for extended local I/O rails, making it ideal for distributed automation systems.

Installation & Setup Guidance

To install the 1794-CE3, first mount the terminal bases and I/O modules on DIN rail in the desired layout. Connect the extender cable between the adapter and the first module, or between any two modules to create a break in the row. Ensure the cable is routed without sharp bends and secured to avoid interference with other components. The open enclosure design means the cable itself has no housing, so it must be installed inside a cabinet for protection.

Compatibility & Integration

The 1794-CE3 is part of the Flex I/O 1794 series and works with all compatible Flex I/O modules and adapters. It supports multiple network protocols including EtherNet/IP, ControlNet, and DeviceNet, allowing seamless integration into existing Rockwell Automation architectures. One adapter can communicate with up to eight I/O modules, handling up to 256 digital points or 96 analog points.

Selection Guide & Purchasing Advice

Before purchasing the 1794-CE3, verify your system layout requirements. If you need a shorter cable, consider the 1794-CE1 (1 foot). For longer runs, the 1794-CE3 at 3 feet is the standard option. Always confirm compatibility with your specific Flex I/O adapter and modules. For complete technical specifications and current availability, contact BluePLC Industrial.
