Allen Bradley 1794-CE3 FLEX I/O 3-Foot Shielded Extender Cable

Product Overview

The Allen Bradley 1794-CE3 provides essential physical flexibility for modular control architectures. This 3-foot (approx. 0.9 meters) shielded extender cable connects FLEX I/O terminal bases to adapters or extends the bus between multiple FlexLogix controllers. It enables multi-row mounting configurations within a single enclosure, allowing engineers to maximize cabinet density. We supply this cable in 100% Brand New condition to ensure optimal signal continuity and electromagnetic protection.

Technical Specifications

This cable utilizes heavy-duty shielding to maintain high-speed communication integrity across the local I/O bus.

Engineering Advantages

• Optimized Enclosure Layouts: The 3-foot length allows for the transition of the FLEX I/O bus from one DIN rail to another. This solves the "horizontal space" limitation common in narrow industrial cabinets by enabling vertical stacking of I/O banks.

• EMI/RFI Suppression: Integrated shielding prevents electromagnetic interference from neighboring high-power components, such as variable frequency drives (VFDs) or contactors. This ensures the digital backplane signal remains clean and error-free.

• Superior Flex Life: The cable features high-flex conductors that withstand the stresses of tight-radius bends during installation. This prevents internal wire fatigue often found in standard commercial-grade cabling.

• Plug-and-Play Integration: The 1794-CE3 features keyed connectors that prevent incorrect orientation. This simplifies field replacement and reduces the risk of pin damage during commissioning in dimly lit control rooms.

FAQs

• Can I daisy-chain multiple 1794-CE3 cables together?

  Allen Bradley does not recommend daisy-chaining extender cables as it increases signal attenuation and may cause communication timeouts on the FLEX I/O bus. Use a single cable of the required length to maintain system stability.

• Is this cable suitable for outdoor installations?

  The 1794-CE3 carries an IP20 rating and an open-style enclosure designation. It requires installation within a NEMA-rated protective enclosure to guard against moisture, conductive dust, and extreme temperature fluctuations.

• How does the shielding connect to the ground?

  The cable connectors automatically engage the ground path through the FLEX I/O terminal base or adapter chassis. Always ensure your DIN rail has a verified path to the system earth ground to maximize the effectiveness of the cable's shield.

• Is this an original Allen Bradley product?

  Yes. We provide only 100% Brand New original 1794-CE3 cables. Using genuine Allen Bradley cables is critical for maintaining the UL and CE certifications of your overall control panel assembly.
