The Honeywell CC-PUIO31 Universal Input Output module is a versatile device that interfaces with a wide range of field devices, including analog input, analog output, digital input, and digital output.

Notable Features

• User Configurable Channels: Each channel can be configured for various functions, including Analog Input, Analog Output, Digital Input, DISOE (Sequence of Events), Digital Output, Pulse Input (up to four channels), and Open Wire Detection.
• Electronic Short Circuit Protection: The module provides electronic short circuit protection to prevent damage to the device.
• Fast Scan: Priority I/O Module Scan ensures quick data processing.
• Safe-State Behaviors: Configurable safe-state (FAILOPT) behaviors are available on a per-channel basis for Digital and Analog Output channels.
• HART Support: The module supports HART 7 for Analog Input and includes a HART Modem per Channel for fast performance.
• Extended Temperature Range: The module can operate in an extended temperature range from -40 to +70°C.

Model Specifications

• Universal Process IO Module: CC-PUIO31
• IOTA Model Numbers:
  • CC-TUIO31 (Non-Redundant, 9″)
  • CC-TUIO41 (Redundant, 12″)

Note 1: 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.
