Compatible Replacement & Equivalent Models
When the original 51204172-175 is unavailable or end-of-life, the following models may serve as functional equivalents or drop-in replacements depending on system configuration:
- 51204172-150 – Earlier revision of the MC-TAOY22; verify firmware compatibility before substitution.
- 51204172-200 – Later revision with enhanced diagnostics; backward-compatible in most TPS configurations.
- MC-TAOY11 (51204160-175) – Single-channel analog output variant; suitable when only one output channel is required.
- 51309288-175 (MC-TAOY22H) – High-density equivalent for upgraded TPS cabinets; requires compatible I/O termination assembly.
- Third-party equivalents: Certain certified aftermarket modules replicate the MC-TAOY22 pinout and signal range — contact Konmask for validated alternatives.
Note: Always verify backplane slot compatibility, firmware revision, and I/O termination assembly (ITA) before installing any replacement module.
Why Choose the Original Model
- Guaranteed compatibility with Honeywell TPS / TDC 3000 backplane and UCN architecture.
- Factory-calibrated 4–20 mA outputs ensure process accuracy without field recalibration.
- Proven reliability in continuous-process industries with 24/7 uptime requirements.
- Full Honeywell diagnostics support via the Universal Control Network (UCN).
- Traceable quality — original modules sourced through authorized channels include full documentation and warranty.
Typical Applications
- Oil & gas refinery process control (valve positioner drives, flow control loops)
- Chemical plant DCS analog output for reactor temperature and pressure control
- Power generation plant turbine and boiler control systems
- Pulp & paper mill process automation
- Pharmaceutical batch process control requiring precise analog signal output
System Compatibility
- DCS Platform: Honeywell TotalPlant Solution (TPS), TDC 3000, PlantScape (with appropriate gateway)
- Card Cage: Honeywell TPS standard card cage (single-slot)
- I/O Termination Assembly (ITA): Compatible ITA required — confirm part number with system documentation
- Firmware: Compatible with standard TPS firmware revisions; verify with Honeywell release notes for specific revision requirements
- Not compatible with: Honeywell Experion PKS (C300 series) without hardware migration kit
Selection Guide
Use the following criteria to confirm the 51204172-175 MC-TAOY22 is the correct module for your application:
- ✅ Your DCS is Honeywell TPS or TDC 3000
- ✅ You require 2-channel analog output (4–20 mA)
- ✅ Your card cage uses standard TPS single-slot form factor
- ✅ Your I/O termination assembly is compatible with the MC-TAOY22 pinout
- ✅ You need a direct replacement for a failed or end-of-life module with no system reconfiguration
If your system requires more output channels, consider the MC-TAOY44 series. If migrating to Experion PKS, consult Konmask for a full migration assessment.

Replacement & Compatibility FAQ
Q: Can I use 51204172-150 instead of 51204172-175?
A: In most cases yes — the -150 and -175 are revision variants of the same MC-TAOY22 module. Verify firmware compatibility with your TPS system version before installation.
Q: Is the MC-TAOY22 compatible with Honeywell Experion PKS?
A: No. The MC-TAOY22 is designed for TPS/TDC 3000 architecture. Experion PKS uses C300-series I/O modules. A hardware migration kit is required for platform upgrades.
Q: Do you supply tested-used modules?
A: Yes. All tested-used units are bench-tested for full output channel functionality and shipped with a test report. A 12-month warranty applies.
Q: What ITA (I/O Termination Assembly) is required?
A: The MC-TAOY22 requires a compatible Honeywell ITA for the TPS card cage. Please provide your existing ITA part number when ordering to confirm compatibility.
Q: Can Konmask source obsolete or hard-to-find revisions?
A: Yes. Konmask specializes in sourcing obsolete and discontinued Honeywell DCS components. Contact us with your exact part number and revision requirement.
