Allen-Bradley 1794-CE3 Flex I/O Extender Cable 3ft Interconnect

Technical Specifications Breakdown

Key parameters for the 1794-CE3 are listed below for quick reference:

Industry Applications

This extender cable is essential for distributed I/O applications where space is at a premium. For example, in a packaging line, you can mount one row of Flex I/O modules near the sensors and another row near the actuators, reducing wiring runs. In process control, the cable allows splitting the system into vertical and horizontal alignments within a cabinet, improving airflow and access. The 1794-CE3 also connects the 1794-FLA to the FlexLogix controller for extended local I/O rails, enabling cost-effective system scaling without a full rack.

Installation & Setup Guidance

When installing the 1794-CE3, ensure it is the only interconnect cable in the Flex I/O 1794 system to maintain signal integrity. The cable has an open enclosure type and supports DIN rail, panel, and wall mounting. Route the cable away from high-voltage lines to avoid noise coupling. The temperature rating is between 0 and 60 degrees Celsius (32 to 140 degrees Fahrenheit), suitable for in-cabinet use. Secure the cable with cable ties to prevent strain on the connectors.

Maintenance & Reliability

Periodically inspect the 1794-CE3 cable for physical damage, such as cuts or crushed areas, especially in high-traffic cabinet areas. Ensure connectors are fully seated and free of debris. The cable's 3-foot length provides flexibility without excessive slack, reducing trip hazards. For long-term reliability, operate within the specified temperature range and avoid exposing the cable to moisture or corrosive atmospheres.

What is the 1794-CE3 Flex I/O Extender Cable?

Struggling to fit a long Flex I/O system into a single row within a tight cabinet? The Allen-Bradley 1794-CE3 interconnect cable offers a practical solution by allowing you to split your Flex I/O 1794 system into two smaller rows. This 3-foot cable, part of the Rockwell Automation Flex I/O 1794 series, enables flexible layouts, whether horizontal, vertical, or on a DIN rail, panel, or wall mount. It is designed as the only interconnect cable in a Flex I/O 1794 system, ensuring reliable communication between the adapter and modules.

Compatibility & Integration

The 1794-CE3 is compatible with the Flex I/O 1794 series, including terminal bases, I/O modules, and adapters. It can be used between any module and adapter to split the system. Flex I/O supports multiple networks such as EtherNet/IP, ControlNet, and DeviceNet, making this cable a versatile component for distributed applications. Terminal bases snap onto DIN rail and provide backplane connections for I/O wiring.

Selection Guide & Purchasing Advice

Choose the 1794-CE3 when you need a 3-foot interconnect cable to arrange your Flex I/O system into two rows. For a shorter 1-foot option, consider the 1794-CE1.
