The Honeywell CC-PUIO31 is a universal 32-channel I/O module designed for the Experion PKS C300 controller platform. As part of Honeywell’s ControlEdge series, this intelligent field interface unit provides flexible signal conditioning for analog/digital inputs and outputs across process industries. The CC-PUIO31 supports 4-20mA, 0-10VDC, RTD, TC, and discrete signals through software-configurable channels, eliminating the need for hardware jumpers.
Featuring dual redundant Ethernet ports and MODBUS TCP/IP protocol support, the Honeywell CC-PUIO31 enables seamless integration with third-party PLCs and SCADA systems. Its built-in HART 7.0 multiplexer allows simultaneous digital communication with 16 field devices while maintaining analog signal integrity. The module’s -40°C to +70°C operational range and Class I Div 2 certification make it ideal for harsh environments in oil refineries and chemical plants.

Key Features and Advantages:
Channel flexibility: The Honeywell CC-PUIO31 eliminates traditional signal conditioning hardware through its patented “Any Channel, Any Signal” technology. Engineers can reconfigure individual channels via Control Builder software in under 30 seconds.
Advanced diagnostics: Integrated waveform capture and signal quality monitoring detect issues like broken wires or ground loops before they cause process deviations. The module’s predictive maintenance algorithm estimates component lifespan with 95% accuracy.
Safety redundancy: Dual independent power domains with automatic load balancing ensure continuous operation during power fluctuations. The hot-swappable design allows module replacement without process interruption.
Application Areas:
The Honeywell CC-PUIO31 excels in:
- Oil & gas: Tank farm pressure/temperature monitoring
- Pharmaceutical: Cleanroom environmental control
- Power plants: Turbine vibration analysis
- Water treatment: Pump station motor control
In LNG terminals, this module simultaneously processes cryogenic temperature measurements (via RTDs), valve position feedback, and HART diagnostics from smart transmitters across 2km field distances.
