Products Description
Honeywell CC-TUIO41 I/O Termination Assembly in stock
Honeywell CC-TUIO41 is the redundant IOTA terminal base for CC-PUIO31 universal I/O module under Experion PKS C300 DCS system. It provides field wiring terminals, signal conditioning and dual-module hot-standby switching circuit to realize redundant I/O configuration.

This conformal coated termination base supports HART signal transmission and channel isolation, matching two CC-PUIO31 cards for redundant operation. It is widely used in petrochemical, refining and power DCS control cabinet spare maintenance.

FAQ
1. Q: What is Honeywell CC-TUIO41?
A: It is redundant IOTA terminal base used together with CC-PUIO31 universal I/O module.2. Q: What is the difference between CC-TUIO31 and CC-TUIO41?
A: CC-TUIO31 is non-redundant base, CC-TUIO41 is redundant version for dual IOM.3. Q: Can it be used on Safety Manager SIS system?
A: No, it belongs to Experion PKS DCS hardware, not SIS safety IOTA base.
