Our Extreme Environment (XT) System [PDF] includes control, communication, and distributed I/O products that extend the benefits of the Rockwell Automation Integrated Architecture to applications with more demanding environmental conditions.
Bulletin 1794 FLEX™ I/O Communication Adapter Modules enable the FLEX I/O modules to exchange data with an I/O scanner across a communication network. Communication adapters are available for EtherNet/IP™, ControlNet™, DeviceNet™, Universal Remote I/O, and other networks. A ControlNet adapter for extreme environments is also available.
Bulletin 1794 FLEX™ I/O offers flexibility for your application with digital, analog, HART analog, and specialty I/O, with 4 to 32 points per module. You can mix and match digital and analog I/O with mounting and wiring options.
Each FLEX™ I/O module requires a terminal base unit that provides terminal connection points for I/O wiring. The terminal bases snap onto the DIN rail and plug together to form the backplane. They are available with screw or spring terminations.
Bulletin 1794 FLEX™ I/O power supplies provide power for the FLEX I/O communication adapter and I/O modules.
