Product Overview

The Honeywell DC-TUIO31 (PN: 51307772-176) is a 32-channel Universal I/O (UIO-2) Termination Assembly for Experion PKS Series C. Each channel can be software-configured as AI, AO, DI, or DO, making it highly flexible for changing field requirements.

The UIO-2 hardware offers enhanced signal density and simplified wiring. G3 conformal coating ensures corrosion resistance in harsh chemical or offshore environments.

Technical Data

Key Features:

• Ultimate Flexibility: Mix AI, AO, DI, DO on a single board.

• Late Binding Advantage: Land cables before finalizing control strategy; configuration is software-driven.

• Compact Footprint: 6-inch vertical design ideal for RIEs or modular skids.

• High-Accuracy Diagnostics: Supports HART on all analog-configured channels for remote monitoring.

Typical Applications

• Modular Process Skids: Standardized interface for OEM equipment with mixed I/O requirements.

• Field Upgrades: Replace legacy 4-20 mA I/O with UIO-2 for HART diagnostics and higher density.

• Oil & Gas Wellheads: Manage diverse AI, DO, and DI devices on a single baseplate.

• Water Treatment Facilities: Control VFDs and monitor sensors in space-constrained distributed networks.

FAQ

Q1: Difference between DC-TUIO31 and DC-TUIO41?
A1: DC-TUIO31 is a non-redundant 6-inch IOTA (single module). DC-TUIO41 is redundant 12-inch, supporting two modules for high availability.

Q2: Can it handle 120 VAC Digital Inputs?
A2: No, strictly 24 VDC. Use interposing relays or 120 V DI modules for AC signals.

Q3: Is it compatible with original UIO modules?
A3: UIO-2 IOTAs like DC-TUIO31 are optimized for latest Series C hardware, but generally maintain backward compatibility with CC-PUIO01. Verify C300 firmware.

Q4: How are channels configured?
A4: Configuration is via Experion Configuration Studio; select channel type from dropdown, and IOTA adjusts automatically.
