Flex I/O is a compact, modular I/O system that consists of I/O modules, terminal bases, and an adapter. This family is ideal because it eliminates the need for separate terminal blocks, in addition to the downtime needed to replace modules, because the modules contain no wiring. The terminal bases remain in place. Up to eight Flex I/O modules may be connected to a single ControlNet adapter in any mix of digital or analog, ac or dc I/O.

  • Reduced Space:
    Wire directly from sensor to terminal base and eliminate the terminal strip
  • Functionality:
    From two point to 32-point modules offer functions of larger rack-based I/O
  • Increased Productivity:
    Easy configuration and setup of I/O modules using wizards speeds engineering and installation
  • Reduced Downtime:
    Removal and Insertion Under Power (RIUP) and module level diagnostics
  • Exceptional Choices:
    More than 90 varieties and specialty modules meet the needs of a wide variety of applications
  • Extreme Environments:
