Honeywell CC-TUIO41 Redundant Universal I/O IOTA Terminal Base for CC-PUIO31

Products Introduction

Product Introduction

Honeywell CC-TUIO41 (CC-TUI041) is the redundant I/O termination assembly (IOTA) designed exclusively for CC-PUIO31 universal I/O module of Honeywell Experion PKS Series C DCS system. It acts as the wiring interface between the universal I/O card and field instruments, integrating terminal blocks, signal conditioning, surge suppression and redundant I/O link circuits. It supports hot swap of the IOM module without disconnecting field cables, widely used in critical process loops requiring high availability.
