1794 FLEX I/O FLEX™ I/O modules offer the functionality of a larger rack-based I/O without the large space requirements. FLEX I/O offers cost-effectiveness, flexibility, modularity, and reliability. Conformally-coated and extreme-environment versions of some modules are available. Intrinsically safe I/O modules are available in the 1797 FLEX Ex™ I/O family. For more information contact Rockwell Automation. For more information about all modules, see FLEX I/O and FLEX Ex I/O Selection Guide, publication 1794-SG002. 1794 FLEX AC Digital Modules Cat.
