Compatible Replacement & Equivalent Models
When the original MC-PHAO01 is unavailable or end-of-life, the following models may serve as functional equivalents or drop-in replacements depending on your system revision and FTA wiring:
- 51403476-150 — OEM part number, same module (alternate label)
- MC-PHAO02 — Revised hardware version; verify firmware compatibility with your C200/C300 controller
- 51304485-100 — Earlier-generation 16-ch AO module; compatible with TDC 3000 legacy racks
- 51304485-150 — Enhanced variant with extended diagnostics; direct FTA-compatible replacement
- MC-TAOX12 — 12-channel AO; suitable for reduced-channel applications with same FTA footprint
⚠ Always verify FTA model, rack slot type, and controller firmware version before substituting modules. Contact Konmask for pre-sale compatibility verification.
Why Choose the Original Model
- Guaranteed OEM compatibility — No firmware re-configuration required; plug-and-play with existing Honeywell FTA and I/O bus
- Validated 16-channel density — Maximizes I/O density per rack slot, reducing hardware footprint
- Proven field reliability — Widely deployed in refinery, petrochemical, and power generation DCS environments
- Full diagnostic support — Supports Honeywell’s online fault detection and channel-level diagnostics via Experion Station
- Long service life — Designed for continuous 24/7 industrial operation with minimal maintenance
Typical Applications
- Control valve positioner output in oil & gas process units
- Variable speed drive (VSD/VFD) speed reference signals
- Analog setpoint transmission to field instruments
- Boiler and turbine control loops in power plants
- Batch process control in chemical and pharmaceutical plants
- Flow, pressure, and temperature control loops in continuous process industries
System Compatibility
| Platform | Compatible | Notes |
|---|---|---|
| Honeywell Experion PKS (C200/C300) | ✅ Yes | Requires matching FTA: MC-TAOX12 or equivalent |
| Honeywell TDC 3000 | ✅ Yes | Use with HPM I/O racks; verify slot type |
| Honeywell PlantScape | ✅ Yes | Legacy system; confirm firmware revision |
| Honeywell Safety Manager | ❌ No | Safety-rated modules required (SIL-certified) |
| Third-party DCS (ABB, Emerson) | ❌ No | Proprietary bus; not cross-compatible |
Selection Guide
Use the following criteria to confirm the MC-PHAO01 is the right module for your application:
- Step 1 — Confirm platform: Verify your DCS is Experion PKS, TDC 3000, or PlantScape. Check controller model (C200, C300, HPM).
- Step 2 — Count AO channels: If you need exactly 16 analog output channels per slot, MC-PHAO01 is optimal. For 8-channel needs, consider MC-TAOX12.
- Step 3 — Verify FTA model: Confirm the Field Termination Assembly (FTA) in your cabinet matches the MC-PHAO01 pinout (typically MC-TAOX12 or 51304516-xxx series).
- Step 4 — Check output type: MC-PHAO01 outputs 4–20 mA. If HART communication is required on outputs, consult Honeywell for HART-capable AO modules.
- Step 5 — Assess condition requirement: Konmask supplies new-surplus, refurbished-tested, and used-pull units. Specify your condition requirement at inquiry.

Replacement & Compatibility FAQ
Q: Can MC-PHAO01 replace 51403476-150 directly?
A: Yes — MC-PHAO01 and 51403476-150 are the same module with different labeling conventions (model number vs. part number). They are interchangeable.
Q: Is MC-PHAO02 a drop-in replacement for MC-PHAO01?
A: In most cases yes, but verify your Experion controller firmware supports the MC-PHAO02 hardware revision. Contact Konmask for a compatibility check.
Q: Can I use this module in a SIL-rated safety loop?
A: No. The MC-PHAO01 is a standard (non-safety) I/O module. For SIL 1/2/3 applications, Honeywell Safety Manager modules with SIL certification are required.
Q: Do you supply the matching FTA for MC-PHAO01?
A: Yes. Konmask stocks common FTA models compatible with MC-PHAO01. Please specify your cabinet wiring type when ordering.
Q: What is the lead time for MC-PHAO01?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time depending on sourcing. Contact us for real-time availability.
