Features:
- Up to 32 channels configurable individually as AI, AO, DI or DO.
- HART 7 on analog I/O and pulse input capability on channels 15 through 18.
- CC-TUIO01 nonredundant or CC-TUIO11 redundant IOTA pairing.
CC-PUIO01 is the Series C universal I/O IOM for mixed analog and discrete signals. Each available channel can be assigned as analog input, analog output, digital input or digital output, subject to module loading and the installed wiring arrangement. Honeywell documents HART 7 on analog channels and pulse input on channels 15 through 18. Analog input uses 0-20 mA or 4-20 mA ranges with 16-bit conversion and a 50 ms scan; analog output uses a 4-20 mA operating range with 12-bit resolution and a 700-ohm maximum load.
The IOTA and lifecycle boundary are part of replacement planning. CC-TUIO01 is the nonredundant 12-inch IOTA and CC-TUIO11 is the redundant 18-inch IOTA; those nominal lengths apply to the IOTA assemblies rather than the plug-in module or shipment. Honeywell's May 2026 update places CC-PUIO01, CC-TUIO01 and CC-TUIO11 in Phase Out status. Spares remain listed for the installed base, but this hardware is not approved for greenfield or brownfield expansion. Preserve the channel database, field wiring, HART assignments, pulse assignments and redundancy design during replacement.
The CC-PUIO01 Honeywell Universal I/O Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell CC-PUIO01 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
Each available channel can be configured for analog input, analog output, digital input or digital output, subject to the documented module-loading rules and the installed IOTA wiring. Confirm every channel personality, field-power source, terminal assignment and safe-state requirement against the control database before replacing the module.
Analog input and analog output channels support HART 7. Channels 15 through 18 can be configured as pulse inputs from 0 to 10 kHz with a 50 microsecond minimum pulse width. Verify that HART assets, pulse scaling, filtering, alarm limits and historian tags are preserved during commissioning.
Honeywell's May 2026 lifecycle table lists CC-PUIO01 with CC-TUIO01 or CC-TUIO11 as Phase Out and not allowed for greenfield or brownfield expansion. The listed expansion path is CC-PUIO31 with CC-TUIO31 or CC-TUIO41 on Experion R432 and above. This is a controlled migration path, not evidence of an unrestricted drop-in replacement; software release, IOTA, wiring and channel configuration require engineering review.
