Product Overview

The Honeywell CC-TUIO31 (Part Number: 51306875-176) is a Universal Input/Output Termination Assembly (IOTA) within the Experion PKS Series C architecture. It provides the physical interface and wiring termination for Universal I/O modules, enabling software-configurable channels that can function as analog inputs, analog outputs, digital inputs, or digital outputs. This flexibility eliminates the need for dedicated I/O hardware for each signal type, reducing system complexity and inventory. The unit is supplied as 100% Brand New Original equipment, manufactured in the United States for mission-critical applications.

Technical Specifications

Engineering Advantages

• Software-Defined Flexibility: Supports Universal I/O modules with independently configurable channels (AI, AO, DI, DO) via software.

• Streamlined Marshalling: Reduces the need for external marshalling cabinets and extensive cross-wiring, lowering installation complexity and cost.

• Enhanced Signal Integrity: High-quality termination design minimizes crosstalk and EMI, ensuring stable signal transmission in harsh environments.

• Redundancy-Ready Design: Supports redundant Universal I/O module configurations for bumpless transfer and improved system availability.

FAQs

What is the difference between a standard IOTA and the CC-TUIO31?
Standard IOTAs are dedicated to specific signal types, while the CC-TUIO31 supports Universal I/O modules that can be configured for multiple signal types on the same assembly.

Does this unit include the electronic I/O module?
No, it is only the termination assembly. The Universal I/O electronic module must be purchased separately.

Is it compatible with 2-wire and 3-wire transmitters?
Yes, it supports multiple wiring configurations, including 2-wire loop-powered and 3-wire/4-wire devices.

Can it be mounted on a DIN rail?
It is designed for the Series C mounting system using a dedicated carrier/rail structure to ensure proper mechanical support and grounding.
