Honeywell CC-TUIO11 51306852-175 Universal Input/Output IOTA

Honeywell CC-TUIO11 Universal I/O Terminal Assembly

The Honeywell CC-TUIO11 (51306852-175), also cataloged as the CC-TUIO11 redundant universal I/O terminal assembly (IOTA), serves as a 32-channel configurable interface for Experion PKS Series C and C300 distributed control systems.

Hardware Specifications

4-20 mA HART Loop Protocol

Each analog channel integrates a HART 7 modem, enabling bidirectional digital communication with smart field instruments. Universal channel technology allows software-defined configuration per channel (AI, AO, DI, DO, pulse input, SOE). High-level isolation prevents interference between channels and ensures deterministic signal acquisition. Event sequence recording (SOE) achieves 1 ms resolution with a 20 ms scan cycle, supporting precise process diagnostics.

Frequently Asked Questions

Q: Can the CC-TUIO11 be hot-swapped during operation? A: Yes, modules can be inserted or removed under power; redundancy ensures unaffected operation of other channels.

Q: How does the module protect against short circuits? A: Electronic short-circuit protection isolates the affected channel, preventing damage to the IOM/IOTA and maintaining operation of other channels.

Q: What is the maximum number of channels supported? A: The assembly supports 32 fully independent software-configurable channels.

Field Installation Guidelines

• Mount the IOTA on a 35 mm DIN rail or directly on a panel.
• Ensure screw terminals are tightened to specification for secure field wiring.
• Segregate analog and digital wiring to minimize interference.
• Maintain airflow clearance around the assembly for thermal management.
• Ground shielding at a single point to prevent ground loops.
• Verify redundancy pairing with CC-PUIO01 modules before commissioning.
