Compatible Replacement & Equivalent Models
The following modules are functionally equivalent or drop-in replacements for the CC-PA0H01 in most Honeywell C300 DCS configurations. Always verify firmware revision and backplane compatibility before substitution.
- Honeywell CC-PA0H01 (51405039-175) — OEM original; direct replacement
- Honeywell CC-PA0H51 (51405039-275) — HART-enabled variant; backward compatible in most racks
- Honeywell CC-PA0H01R — Redundant-capable version for high-availability loops
- Honeywell 51304516-150 MC-PAOY22 — Legacy TDC 3000 / PlantScape AO module (requires I/O link adapter)
- Third-party equivalents: Emerson KJ3221X1-BA1 (DeltaV AO), ABB AI835A — functionally similar 4–20 mA AO modules; require gateway or migration adapter for Honeywell DCS integration
Note: Cross-brand substitution requires engineering validation. Contact Konmask for compatibility assessment.
Why Choose the Original Model
- Guaranteed DCS Compatibility: Factory-validated for Experion PKS C300 — no firmware patching or adapter required.

Selection Guide
Use the following criteria to select the correct analog output module for your application:
- Standard 4–20 mA output, no HART required → CC-PA0H01 (51405039-175) ✓ This model
- HART device communication required → CC-PA0H51 (51405039-275)
- High-availability / redundant output loops → CC-PA0H01R (redundant pair)
- Legacy TDC 3000 / PlantScape migration → MC-PAOY22 (51304516-150) with I/O link
- SIL-rated safety loops → Consult Honeywell Safety Manager I/O catalog; standard CC-PA0H01 is not SIL-rated
- Budget-constrained retrofit → Contact Konmask for certified refurbished CC-PA0H01 availability

Replacement & Compatibility FAQ
Q: Can the CC-PA0H01 replace the CC-PA0H51 directly?
A: Yes, in non-HART applications. The CC-PA0H01 is the base model without HART; if your field devices use HART protocol, you must use CC-PA0H51.
Q: Is the 51405039-175 compatible with older Experion PKS R300 systems?
A: Compatibility with R300 is not guaranteed. Honeywell recommends R400 or later. Contact your Honeywell system integrator for a firmware compatibility check.
Q: Can I use a third-party AO module (e.g., Emerson DeltaV) in a Honeywell C300 rack?
A: No — third-party modules are not physically or electrically compatible with the CIOM-A backplane. A migration gateway or full I/O replacement is required.
Q: What is the difference between 51405039-175 and 51405039-275?
A: The -275 suffix corresponds to the CC-PA0H51 (HART-enabled). The -175 is the standard CC-PA0H01 without HART. Both share the same physical form factor and backplane pinout.
Q: Do you supply certified refurbished units?
A: Yes. Konmask offers certified refurbished CC-PA0H01 modules with inspection reports. Contact us for availability and pricing.
