Bulletin 1794 FLEX I/O Communication Interfaces

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.

Features

  • Interfaces FLEX™ I/O modules with a communication network
  • Built-in power supply converts 24V DC to 5V DC for the backplane to power the FLEX I/O modules
  • Supports up to eight I/O modules for up to 256 points
  • FLEX-I/O XT™ extreme environment modules are rated for -20...70 °C (-4....185 °F) and are compatible with the ControlLogix-XT™ extreme environment system
  • Conformal coated modules are available
