CC-TUIO31 Honeywell Experion PKS Series C Universal I/O IOTA Board

Configured for field signal termination and routing in Experion PKS Series C automation platforms, the Honeywell CC-TUIO31 (CC-TUIO31 Universal I/O Board) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

The CC-TUIO31 Universal Input Output Termination Assembly (UIOTA) connects field instruments directly to the matching Series C Universal I/O Module (UIOM). Built to handle software-configurable channels—including 4-20 mA HART loop protocol instruments, digital inputs, and digital outputs—the assembly incorporates galvanic channel-to-channel isolation. This electrical boundary suppresses common-mode noise, prevents ground loop currents, and isolates field-induced transients from reaching internal processing circuitry.

Frequently Asked Questions

Q: Can an active Universal I/O Module be replaced without disconnecting field conductors from the CC-TUIO31 board?

A: Yes, field wiring remains connected to the CC-TUIO31 board terminals, allowing the associated active Universal I/O Module to be hot-swapped online without disturbing field loops.

Q: How are individual channel operational types assigned on the CC-TUIO31 hardware?

A: Channel modes (analog input, analog output, digital input, digital output) are assigned via software in the Experion PKS Control Builder, requiring no physical jumpers on the board.

Q: Does the CC-TUIO31 terminal assembly require direct power connection?

A: No, the board functions as a passive interface; field instrument loop power is supplied via the backplane connections through the attached I/O module.

Field Installation Guidelines

1. Lock the CC-TUIO31 assembly onto the Series C vertical DIN rail channel until all retaining clips fully engage.
2. Terminate field signal conductors to the removable screw terminal blocks using recommended wire stripping lengths and torque specifications.
3. Ground all signal cable shield drains directly to the cabinet earth grounding bar to prevent electromagnetic interference (EMI) from coupling into analog loops.
4. Align the multi-pin interface of the Universal I/O Module with the CC-TUIO31 board header and push firmly until fully seated.
