1794-CE3 | Allen-Bradley Extender Cable

The Allen-Bradley 1794-CE3 cable is specifically designed to extend and organize the FLEX I/O system. It allows users to reconfigure the system into two rows or separate horizontal and vertical layouts to optimize cabinet space. The cable serves as a communication bridge between the 1794-FLA adapter and a FlexLogix controller. This extension ensures continuity of the local FLEX I/O rail, enabling system scalability without compromising signal integrity. It is essential in distributed control applications where modular and flexible layouts are required. The 1794-CE3 enhances system flexibility and streamlines physical wiring architecture.

The 1794-CE3 cable is 0.9 meters long, which is equivalent to approximately 3 feet. This length is ideal for installations inside control cabinets where space constraints are common. It provides enough reach to interconnect modules across short gaps or through angled pathways. The compact size helps minimize signal degradation while offering efficient cable management. Users often employ this cable when creating tiered or side-by-side module layouts. Its fixed length ensures consistent performance and simplifies installation planning.

Yes, the 1794-CE3 is perfectly suitable for both horizontal and vertical FLEX I/O configurations. The cable is intentionally designed to support modular layouts that may not follow a single straight line. Its flexibility allows modules to be arranged in stacked vertical tiers or angled panels as needed. This is particularly useful when control panels are tall or when components need to be organized by functional groups. Vertical layout support makes the system more adaptable to real-world mechanical constraints. Just ensure the cable is routed to avoid strain or interference with other panel components.

The 1794-CE3 uses an open-style construction, which means it lacks an external protective sheath or insulation enclosure. This allows for greater flexibility during installation and makes it easier to route the cable through confined areas. While it simplifies handling and integration, this design is best suited for use within enclosed or controlled environments. Exposure to liquids, abrasives, or high temperatures should be avoided. For added protection in demanding conditions, external conduits or cable trays may be used. The open-style format reflects its purpose as an internal connection cable, not for exposed field use.

Yes, as of now the 1794-CE3 is still in production and widely available through Rockwell Automation and authorized distributors. It remains a standard accessory for FLEX I/O systems and is commonly included in both new installations and retrofit projects. Due to its essential role in extending communication paths between FLEX modules, it is unlikely to be discontinued without a direct replacement. Users are encouraged to use original parts to maintain system certification and ensure electrical compatibility. Availability can vary by region, so it’s recommended to check with local suppliers or Rockwell’s catalog for current status.
