Product Introduction
You don’t install a CC-PAON01 because it’s exciting. You install it because a control valve on unit 3 lost its 4-20mA drive signal at 2 AM, and the old card’s channel LED went dark. This is the non-HART 16-channel analog output module for Honeywell’s C300 controller in the Experion PKS platform. It sits in the C-Series I/O rack, takes digital setpoints from the controller, and pushes 4-20mA out to positioners, dampers, and flow controllers.The reason field engineers keep this card in the spare parts cabinet is simple: it’s dense (16 channels in a narrow slot), it runs cold, and it doesn’t need HART overhead when all you need is a clean current loop. The -40°C to +85°C range means it survives unconditioned junction boxes that would kill a standard PLC card. Just remember — this is the non-HART version. If your loop needs device diagnostics or remote ranging, you want the CC-PAOH01 instead.
Quality SOP & Tech Pitfalls
The Lab Report (SOP)
Every unit ships through a four-step gate:
- Visual & counterfeit check — housing, connector pins, label font, and part number 51410070-175 verified against known OEM markings.
- Live rack test — seated in a C300 I/O chassis with 24VDC applied, all 16 channels sourced into a Fluke 754 process calibrator to verify 4-20mA linearity and channel isolation.
- Insulation & supply check — multimeter verification of supply draw (~5W typical) and channel-to-channel isolation.
- Anti-static sealing — module bagged with desiccant, foam-packed, with test readings logged. Photos or video available on request.
The Engineer’s Warning (Pitfalls)
- Wrong sibling card: CC-PAON01 (no HART) and CC-PAOH01 (HART) look identical and fit the same slot. Swapping one for the other without updating the Control Builder device type will give you a healthy-looking LED and zero output. I’ve watched a turnaround burn six hours on this.
- Terminal board mismatch: This module requires the correct C-Series IOTA terminal base (e.g., CC-TAOX01 for non-redundant, CC-TAOX11 for redundant AO). The wrong base means no backplane communication, period.
- Ground loops on long runs: Shielded twisted pair, grounded at one end only. I’ve seen 60 Hz noise ride a 200-meter unshielded run and make a valve hunt ±5% all day.
Installation & Configuration Guide
30-Minute Swap Procedure
- Pre-Installation ⚠️
- Notify operations and place the affected control loops in manual.
- Verify redundant C300 controller health before touching I/O.
- Photograph the existing module label, terminal wiring, and LED states.
- Removal
- Label each field wire with its channel number.
- Release the IOTA terminal base locking clips (if removing the base).
- Slide the failed module straight out — no twisting.
- Installation
- Confirm the replacement reads CC-PAON01 / 51410070-175. Not PAOH01, not PAOX01.
- Seat the module firmly into the IOTA base until the latch clicks.
- Reconnect field wiring per your photograph. Check polarity on every loop.
- Power-On & Testing
- Verify 24VDC at the terminal block (23-25VDC range).
- Watch the LED boot sequence: power OK, then channel status.
- Force each output from Control Builder and verify mA at the terminal with a calibrator.
- Return loops to auto only after all 16 channels read within tolerance.
Compatible Replacement Models
| Compatibility Tier | Model | Notes |
|---|---|---|
| ✅ Drop-in Replacement | CC-PAON01 (51410070-175) | Same module, no config change needed. |
| ✅ Drop-in Replacement | CC-PAON01 (alternate revision) | Functionally identical; verify suffix with OEM docs. |
| ⚠️ Software Compatible | CC-PAOH01 (HART AO, 16-ch) | Same slot/base, but requires HART device type in Control Builder and loop review. |
| ⚠️ Software Compatible | CC-PAOX01 (AO, non-HART) | Alternative C300 AO variant; confirm channel count and base compatibility before swapping. |
| ❌ Hardware Mod Required | MC-PAOY22 (legacy PM I/O) | Older Experion generation — different chassis, different backplane. Full migration project. |
Frequently Asked Questions (FAQ)
Can I hot-swap this module?
Yes — C300 I/O modules are designed for hot insertion/removal. That said, always put the affected loops in manual first. “Hot-swappable” doesn’t mean “consequence-free” if a valve slams shut during the swap.What’s the difference between CC-PAON01 and CC-PAOH01?
HART. The CC-PAON01 is a plain 4-20mA output. The CC-PAOH01 adds HART communication for remote device diagnostics and configuration. They share the same physical form factor but are not software-interchangeable without a config change.Does this module work with redundant C300 controllers?
Yes. Pair it with a redundant IOTA base (CC-TAOX11) for channel-level redundancy. The non-redundant base is CC-TAOX01.What terminal base do I need?
CC-TAOX01 (non-redundant) or CC-TAOX11 (redundant). Using the wrong base is the fastest way to get a blank LED and a phone call from operations.Is this still available new from Honeywell?
The C300 platform remains supported within Experion PKS, but individual module availability varies by region and revision. Most units in the secondary market are New Surplus or refurbished. Always confirm the part number and revision before purchasing.What warranty do you offer?
Standard 12-month warranty on all tested units. Pre-shipment test readings (channel mA output, supply draw, insulation) can be provided on request.Will it work with a C200 or C100 controller?
No. The CC-PAON01 is a C-Series I/O module for the C300 controller chassis. C200/C100 use different I/O families. Check your controller model before ordering.
