Honeywell CC-PUIO31 / FC-IOTA-R24 – Redundant IO Termination Assembly | Experion PKS C300 Platform
Engineering Background
The Honeywell Experion PKS (Process Knowledge System) is one of the world’s leading Distributed Control System (DCS) platforms, widely deployed in oil & gas, refining, petrochemical, power generation, and advanced manufacturing. The C300 Controller series forms the backbone of Experion PKS field I/O architecture, demanding termination assemblies that meet the highest standards of signal integrity, redundancy, and long-term reliability.
Product Positioning
The CC-PUIO31 / FC-IOTA-R24 is a factory-engineered Redundant IO Termination Assembly designed specifically for Honeywell Experion PKS C300 systems. It provides a certified, plug-and-play termination interface that supports redundant I/O module configurations, eliminating single points of failure in critical process control loops. Procurement engineers sourcing replacement or expansion hardware for Experion PKS installations will find this assembly a direct, specification-matched solution.

System Architecture & Signal Flow
In the Experion PKS C300 architecture, the IOTA (I/O Termination Assembly) serves as the physical interface between field instrumentation cables and the Series C I/O modules. The CC-PUIO31 / FC-IOTA-R24 assembly accommodates dual I/O module slots in a redundant configuration. Field signals enter via screw terminals on the IOTA, are routed through the backplane connectors to the primary and secondary I/O modules simultaneously. Upon primary module failure, the C300 controller seamlessly switches to the redundant module with no signal interruption — a critical requirement for Safety Instrumented System (SIS) adjacent applications and high-availability process loops.
Sourcing & Quality Verification

Technical FAQ
Q: Is the CC-PUIO31 compatible with non-redundant C300 I/O configurations?
A: The FC-IOTA-R24 is specifically designed for redundant module pairs. For simplex (non-redundant) configurations, consult Honeywell’s Experion PKS I/O selection guide for the appropriate IOTA variant.
Q: Can this assembly be used with Honeywell Safety Manager or FSC systems?
A: No. The CC-PUIO31 / FC-IOTA-R24 is certified for Experion PKS C300 process control I/O only. Safety-rated SIS applications require dedicated Honeywell Safety Manager hardware.
Q: What is the lead time for in-stock units?
A: In-stock units typically ship within 1–3 business days. Contact us for real-time inventory status.
Q: Do you provide a warranty?
A: Yes. Konmask.com offers a 90-day functional warranty on all hardware. Extended warranty options available upon request.
Q: Is export licensing required for shipment to my country?
A: Honeywell DCS components may be subject to EAR (Export Administration Regulations) controls. Konmask.com handles all standard export documentation; buyers in restricted jurisdictions should confirm compliance requirements with their import authority.
