Product Introduction
The Honeywell CC-TAON11 is the redundant field termination assembly for 16-channel, non-HART analog output on Experion PKS Series-C — it’s the wiring interface for CC-PAON01 IOMs driving 4-20 mA current loops to actuators, valve positioners, and recording devices. Since it carries no active electronics, the IOTA supplies field power directly with no external marshalling required.
The 12″ redundant footprint accepts a second CC-PAON01 IOM on the same assembly for hot backup — no external redundancy cabling needed. If your loop needs HART configuration or status, this isn’t the right IOTA; step up to CC-TAOX11 or CC-GAOX11 paired with a HART-capable IOM instead.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No power to the IOM | IOTA not receiving 24 VDC bus power | ✅ High | Measure incoming 24 VDC at the IOTA power terminals | Check upstream power supply — the IOTA has no active electronics of its own |
| One channel outputs 0 mA / open-circuit fault | Broken field wiring at the terminal | ❌ Low | Measure loop current and continuity at the IOTA terminal | Correct field wiring first — the IOTA is passive |
| All 16 channels dead | IOM fault, not the IOTA | ✅ High | Swap in a known-good CC-PAON01 IOM on the same IOTA | If the fault follows the IOM, the IOTA is fine — replace the IOM instead |
| Redundant IOM won’t switch over cleanly | IOTA seating issue or partner IOM fault | ✅ Medium | Check both IOM status LEDs and reseat if needed | Verify IOTA connector seating before condemning either IOM |
| Suspected IOTA damage (physical) | Corrosion, cracked terminal, mechanical damage | ✅ High | Visual inspection of terminals and connector pins | Replace IOTA — physical damage is the main failure mode on passive hardware |
Since this IOTA has no signal-conditioning electronics, most “IOTA faults” reported in the field trace back to wiring or the paired IOM. If hardware damage is confirmed, send terminal and connector photos to support for verification.
Frequently Asked Questions (FAQ)
Is this the analog output module, or just the termination assembly?
Just the termination assembly. CC-TAON11 has no signal-conditioning electronics — it’s the field wiring interface. You still need a CC-PAON01 IOM plugged into it to actually drive the current loop.
Does this IOTA support HART?
No. CC-PAON01, the IOM this IOTA is built for, doesn’t do HART. If you need HART configuration/status on your output loops, you want CC-PAOH01/51 paired with CC-TAOX01/11 or CC-TAOX51/61 instead — different IOM, different IOTA.
Is the CC-TAON11 hot-swappable?
The IOTA itself is generally not pulled live — de-energize the rack slot before removing it. The IOM plugged into it follows the standard no-live-insertion rule for Series-C IOMs.
Do I need this IOTA for a non-redundant setup?
No — for the same 16-channel, non-HART output configuration without redundancy, use CC-TAON01 (6″ footprint) instead. CC-TAON11 is specifically the 12″ redundant version.
Will swapping the IOM on this IOTA wipe my output configuration?
No. Output range, scaling, and FAILOPT settings live in the Experion Control Builder database, not on the IOTA or IOM. The controller re-downloads configuration to the replacement module.
Why is this cheaper than a factory-direct quote?
This is a New Surplus/New Original unit — factory-sealed, serial-verified, never installed — sourced outside Honeywell’s direct sales channel. You skip the OEM markup and lead time; our inspection and warranty terms stand in for a factory warranty.
What’s tested on a termination assembly before it ships?
Since it’s passive hardware, testing focuses on physical and electrical integrity: continuity check across all terminal paths, visual inspection for corrosion or damage, connector pin inspection, and a mated fit-check with a known-good CC- IOM. Photos available on request.
