FLEX I/O Digital Sourcing Input Module 1794-IV32

Overview:

• Input Module: 24V DC, 32 Sourcing Inputs
• Features:
  • Wide electrical range supported
  • Input densities ranging from 8 to 32 points
  • Available isolated inputs or outputs, protected outputs, electronic fusing, or diagnostics on some modules
  • Removal and Insertion Under Power (RIUP) allows module replacement and cable connections while the system is operating
  • FLEX-I/O XT™ extreme environment modules: Rated for -20...70 °C (-4...185 °F), compatible with the ControlLogix-XT™ system
  • Terminal base required for I/O wiring connections
  • Direct wire connection from the sensor to the terminal base eliminates the need for a terminal strip
  • Conformally coated modules available upon request
