Allen Bradley 1794-CE3 Flex I/O Extension Cable

Applications

• FLEX I/O system physical extension between adapter and I/O terminal bases

• Split-rack or dual-row FLEX I/O layouts in control cabinets

• Horizontal or vertical reconfiguration of distributed FLEX I/O systems

• Connection between 1794-FLA modules and FlexLogix controller assemblies

• Panel redesigns requiring separation of I/O islands within the same system

• Industrial automation retrofits where cabinet space constraints require flexible I/O placement

• Machine-level control systems needing modular and reconfigurable I/O architecture

Key Advantages

• Flexible 0.9 m (3 ft) extension enabling adaptable FLEX I/O cabinet layouts

• Supports both split-system and multi-row I/O configurations

• Shielded industrial-grade construction for reliable signal integrity

• Simplifies complex panel layouts without redesigning backplane structure

• Compatible with FLEX I/O adapters and terminal base assemblies

• Improves serviceability by allowing physically separated I/O groups

• Rugged design suitable for industrial vibration and EMI environments

Technical FAQs

1. What is the main function of the 1794-CE3 cable?
It extends the FLEX I/O communication and backplane connection between system components.

2. What is its length?
The cable is 0.9 meters (3 feet) long.

3. What systems is it compatible with?
It is used with Allen-Bradley FLEX I/O systems, including 1794 series modules.

4. Can it be used for both input and output modules?
Yes, it supports full FLEX I/O system configurations.

5. Does it require configuration?
No configuration is needed; it is a passive extension cable.

6. What type of connection does it use?
It uses industrial-grade FLEX I/O connector interfaces (system-specific).

7. Is it suitable for harsh environments?
Yes, it is designed for industrial cabinet environments with EMI resistance.

8. Can it be used to extend multiple racks?
It is intended for system layout extension, not unlimited cascading.

9. Does it affect communication speed?
No significant impact when installed within specification limits.

10. Is it compatible with modern EtherNet/IP FLEX I/O adapters?
Yes, it is used within FLEX I/O architecture regardless of communication type.
