Notable Features

• Each channel user configurable as:
  • Analog Input
  • Analog Output
  • Digital Input
  • Digital Output
  • Pulse Input (channels 15-18)
• Open Wire Detection
• Fast Scan (Priority I/O Module Scan)
• Electronic short circuit protection

Parameter Specification

Universal Process IO Module CC-PUIO01

• IOTA Model Numbers:
  • CC-TUIO01 Non-Redundant 12”
  • CC-TUIO11 Redundant 18”

(Note: Each signal can be shorted in the field with no damage to the IOM or IOTA. Other channels on the same IOM will not be affected. AI, AO, and DI channels are further protected and certified to support energy-limited/non-incendive field wiring connections to Zone 2/Division 2 hazardous locations.)
