✅ Product Overview – Honeywell CC-TUIO31 (51306875-176)
📌 Product Description
The Honeywell CC-TUIO31 is a Universal Input/Output Termination Module, designed for industrial control applications as part of the Series-C distributed I/O architecture. It provides a non-redundant, coated, flexible I/O platform, capable of interfacing with analog, digital, and pulse signals from field instruments and control devices. Its universal design minimizes the need for multiple dedicated modules, which simplifies the design and maintenance of control systems.
This module is typically installed in remote I/O cabinets or directly in process environments and connects to the controller via Honeywell’s I/O link. It is engineered for robustness, high channel density, and environmental resilience, suitable for both general and industrial process automation use cases.

❓ FAQ (Q&A Format)
Q1: What types of signals can be connected to the CC-TUIO31?
A1: The module supports analog inputs/outputs, digital inputs/outputs, and pulse signals, all through configurable terminals.
Q2: Is the CC-TUIO31 suitable for redundancy?
A2: No, it is a non-redundant module. For redundant installations, Honeywell offers the CC-TUIO41 model.
Q3: How many I/O points does it support?
A3: It can support up to 128 configurable I/O points depending on system configuration and signal type.
Q4: What protection does the “coated” version offer?
A4: The conformal coating protects the circuitry against dust, humidity, and corrosive gases in industrial environments.
Q5: Can this module be hot-swapped?
A5: No, the CC-TUIO31 must be de-energized before replacement unless the system is designed for hot-swapping via redundancy.
Q6: Is this module compatible with legacy Honeywell systems?
A6: It is designed for Series-C and Experion PKS architectures. Compatibility with older systems depends on available adapters or upgrades.
Q7: What happens if a channel is shorted?
A7: The module provides internal protection to isolate faulted channels, but persistent faults may require module replacement.
Q8: What is the expected operating life of the module?
A8: With proper installation, the CC-TUIO31 can operate reliably for over 10 years in industrial environments.
Q9: What are the wiring requirements?
A9: Standard shielded twisted pair cables are recommended for analog signals. Digital and pulse wiring should follow Honeywell installation standards.
Q10: Is the module firmware upgradeable?
A10: The IOTA itself does not typically contain firmware; the associated IO Processor (IOP) module holds the firmware logic.
