The CC-PUIO31 is an advanced Universal Input/Output (UIO) module within the Honeywell Experion PKS Series C I/O family. It provides 32 fully configurable channels, allowing each channel to be independently set as an analog input, analog output, digital input, or digital output through software configuration in the Experion environment.
This flexibility eliminates the need for multiple dedicated I/O modules, simplifying system design, reducing spare parts inventory, and minimizing cabinet complexity. The CC-PUIO31 also features advanced onboard processing for high-speed pulse accumulation and signal filtering, making it well-suited for modern data-intensive industrial applications.

The CC-PUIO31 is widely used in modular process skids, chemical refineries, and pharmaceutical production facilities. It is particularly valuable in dynamic environments where instrument types may change during project execution. Its universal configuration capability allows engineers to reassign I/O types via software without modifying hardware or rewiring cabinets, greatly improving flexibility and reducing lifecycle costs.
What are the primary benefits of Universal I/O over traditional modules?
The CC-PUIO31 eliminates I/O mismatch issues during commissioning. Instead of replacing hardware when signal types change, users can simply reconfigure channels in software, reducing engineering effort, costs, and downtime.
Can this module be used for high-speed counting?
Yes. The CC-PUIO31 supports up to 4 high-speed pulse input channels with frequencies up to 15 kHz, making it suitable for applications such as flow metering and high-speed counting systems.
