Honeywell CC-TAOX01 six-inch non-redundant Series C analog-output IOTA for CC-PAOH01 or CC-PAOX01 modules.
Honeywell CC-TAOX01 is the six-inch, non-redundant Series C Analog Output I/O Termination Assembly. It provides the physical termination and interface between the installed analog-output IOM and field devices.
The approved IOM pairings are CC-PAOH01 for HART-capable analog output and CC-PAOX01 for analog output without HART. The IOTA does not create HART functionality by itself; communication capability follows the installed IOM and the configured field device.
The existing page title is retained unchanged, while the product description distinguishes the CC-TAOX01 IOTA from the removable signal-processing IOM. This distinction is important for spare selection and troubleshooting.
| Model | CC-TAOX01 |
| Honeywell part number in related product records | 51308351-175 |
| Product form | Analog Output I/O Termination Assembly (IOTA) |
| Series | Experion Series C |
| Nominal IOTA size | 6 inches / 152 mm |
| Redundancy | Non-redundant |
| Redundant counterpart | CC-TAOX11, 12-inch redundant AO IOTA |
| Compatible IOMs | CC-PAOH01 and CC-PAOX01 |
| System channel count with paired IOM | 16 analog-output channels |
| System output type with paired IOM | 4–20 mA |
| HART capability | Available with CC-PAOH01; not provided by the IOTA alone |
| Paired-IOM maximum resistive load | 800 ohms with the documented 24 V supply range |
| Paired-IOM response | Settles within 1% of final value within 80 ms |
| Field connector capacity | Up to 12 AWG / 2.5 mm stranded wire |
| Critical configuration checks | IOM model, field wiring, power, safe-state settings and cabinet layout |
Use CC-TAOX01 only with an approved Series C analog-output IOM. Pairing it with CC-PAOH01 supports the HART-capable architecture; pairing it with CC-PAOX01 supports the non-HART architecture.
System performance values such as output accuracy, load capability and response time belong to the installed IOM-and-IOTA assembly. When troubleshooting, separate IOM diagnostics from terminal, wiring and field-load checks on the IOTA.
Confirm cabinet power, field termination, channel assignment and grounding before commissioning. The redundant CC-TAOX11 is a different physical arrangement and should not be substituted without an approved redundancy design.
Mount and ground the IOTA according to the Series C cabinet procedure, then verify power before installing the IOM. Confirm that the complete CC-TAOX01 marking matches the project bill of materials.
Land field conductors according to the channel wiring drawings. Check polarity, shield practice, field-load resistance and the availability of the required loop power before enabling outputs.
After fitting the IOM, verify recognition, diagnostics, output readback, safe-state configuration and open-wire behavior. Commission the loop through the full required operating range and record the result.
Treat the IOTA and IOM as related but separately replaceable assets. Record both model numbers, revisions, terminal assignments and field wiring so that future maintenance does not confuse the termination assembly with the electronics module.
Before converting to redundancy or a later analog-output family, review the IOTA footprint, wiring, HART requirements, Experion release and shutdown plan.
No. It is the six-inch non-redundant I/O Termination Assembly that accepts a compatible analog-output IOM.
Honeywell lists CC-PAOH01 and CC-PAOX01 for this IOTA.
No. HART capability is available when the HART-capable CC-PAOH01 IOM is installed and configured.
The approved paired IOM architecture provides sixteen analog-output channels.
CC-TAOX11 is the documented twelve-inch redundant analog-output IOTA.
Check IOM pairing, channel wiring, polarity, field load, power, diagnostics, readback and safe-state behavior.
