CC-PAOH01 / 51405039-175 — Honeywell Series C 16-Channel Analog Output with HART
CC-PAOH01, also purchased under spare number 51405039-175, is Honeywell’s high-level analog output module with HART for Experion Series C. It drives constant current to valves, positioners, and indicating devices and can exchange HART data with multivariable instruments. HKXY Instruments is a China industrial automation trader with 15 years of export experience, not the OEM.
Product identity
| Item | Reference |
|---|---|
| Manufacturer | Honeywell |
| Model | CC-PAOH01 |
| Spare / material number | 51405039-175 |
| Function | High-level analog output with HART, 16 channels |
| Non-HART relatives | CC-PAOX01 / CC-PAON01 — different models; not automatic substitutes |
Paired IOTA options
Honeywell lists these IOTAs with CC-PAOH01:
- CC-TAOX01 — non-redundant analog output IOTA, 6 inch
- CC-TAOX11 — redundant analog output IOTA, 12 inch
- CC-GAOX21 — non-redundant GI/IS-style IOTA, 6 inch
- CC-GAOX11 — redundant GI/IS-style IOTA, 12 inch
Order the electronics and the installed IOTA style as one system. A redundant cabinet that uses CC-TAOX11 will not accept a non-redundant 6-inch board without a documented redesign.

| Compliant / open-circuit voltage | 16 V maximum compliant; 22 V maximum open-circuit |
| Response time | Settles to within 1% of final value within 80 ms |
| Redundant switchover gap | 10 ms maximum (0 mA gap to field) |
Engineering behaviors that affect replacement
- FAILOPT is configurable per channel: HOLD LAST VALUE or SHED to a SAFE VALUE. If the IOM electronics fail, Honeywell documents that the output goes to zero (the safe state).
- Open-wire detection can annunciate an open field wire as a channel soft failure.
- Output read-back can alarm on discrepancy between commanded and measured current.
- HART support is intended for HART-capable multivariable instruments; multiple modems are documented for faster collection of control variables.
RFQ checklist
- Confirm both CC-PAOH01 and 51405039-175 (or the exact number printed) on the nameplate.
- Identify the IOTA: CC-TAOX01, CC-TAOX11, CC-GAOX21, or CC-GAOX11.
- Record loop load (Ω), whether HART is active, and each channel’s FAILOPT setting.
- Note redundancy, firmware context, and any stroke-test or SIS-related output constraints [TO CONFIRM with project documents].
- Quantity, destination, inspection scope. Commercial terms are [TO CONFIRM].

FAQ
Is 51405039-175 a different product from CC-PAOH01?
It is the spare/material number commonly printed with CC-PAOH01. Still match both strings on the label before you buy.
Will this module work without HART instruments?
It outputs standard 4–20 mA. HART is available for compatible devices. A non-HART AO model (CC-PAON01 / CC-PAOX01) is a different catalog item and must be approved separately.
What field load can it drive?
Honeywell specifies a maximum resistive load of 800 Ω when the 24 V supply is between 22 and 28 VDC, with 16 V maximum compliant voltage.
What happens on a module electronics failure?
The documented safe state for an IOM electronics failure is zero output, regardless of the configured FAILOPT hold or shed selection.
Do you guarantee stock on this page?
No. Stock, price, and lead time are [TO CONFIRM] after code verification.
