Honeywell CC-PUIO31 (UIO-2) Honeywell Universal Mixed I/O Module

1. Basic Positioning and Compatible Platform
Full Name: Universal Input/Output Module UIO-2 General Purpose I/O Card
System: Experion PKS C300 / C200 Controllers (Series C I/O Series)
System Version Requirement: Supported by Experion R430 and later firmware versions
Part Number: 51454220-176
Key Advantages: Single module with 32 channels, software-defined functionality allowing flexible switching between AI/AO/DI/pulse input without hardware replacement, significantly reducing spare parts variety

32-channel fully compatible signal types (single-channel software configuration)
1. Analog Input (AI)
4–20mA two-wire transmitters, native HART 7 (independent HART modems per channel)
Thermocouples (TC), resistance temperature detectors (RTD), 0–10V voltage signals
Wire break/short circuit diagnostics, loop fault detection

2. Analog Output (AO)
4–20mA output, maximum load capability of 825Ω@20mA
Customizable independent fail-safe value (FAILOPT) per channel

3. Digital Input (DI)
24VDC dry/wet contacts, supports SOE (Sequence of Events) recording (1ms time resolution, PV scan rate 20ms)

4. Digital Output (DO)
24VDC transistor output with hardware electronic short-circuit protection

5. Pulse Input
Any four channels configurable for pulse acquisition, with wire break detection

Core Function Highlights
Independent HART per channel: Multiple intelligent instruments can communicate simultaneously without occupying the bus bandwidth
High-density mixed IO: Replace multiple single AI/AO/DI cards, reducing the space of the IO cabinet
Full-channel self-diagnosis: Remote upload of short-circuit, open-circuit, and module failure alarms
Redundancy option: Compatible with CC-TUIO41 base unit to achieve 1:1 redundancy of IO modules
Fast scanning: Prioritize high-speed IO acquisition to meet the real-time requirements of closed-loop control
