Honeywell MC-PHAO01 / MC-PLAM02 / MC-PSIM11 Low Level Analog Mux | Replacement, Equivalent & Selection Guide
The Honeywell MC-PHAO01, MC-PLAM02, and MC-PSIM11 are low-level analog multiplexer (mux) I/O modules designed for Honeywell’s Experion PKS and TDC 3000 distributed control systems (DCS). These modules handle low-level analog signal conditioning and multiplexing for process measurement inputs such as thermocouples and RTDs. Konmask.com supplies genuine and compatible replacement units with full traceability.

Always verify hardware revision and firmware version with your DCS system engineer before substituting modules.
Why Choose the Original Model
- Factory-calibrated for Honeywell DCS backplane signal integrity
- Guaranteed compatibility with Experion PKS R400–R520 and TDC 3000 LCN/UCN
- Supports Honeywell’s FDM (Field Device Manager) diagnostics
- Minimizes re-engineering risk in brownfield plant upgrades
- Backed by Honeywell’s global spare parts and lifecycle support program
Typical Applications
- Thermocouple and RTD temperature measurement in refinery and petrochemical plants
- Low-level mV signal acquisition in power generation control systems
- Analog I/O expansion in existing Experion PKS or TDC 3000 cabinets
- Replacement of failed or end-of-life mux cards during planned shutdowns
- Spare parts inventory for critical process control infrastructure
System Compatibility
- Honeywell Experion PKS — R400, R410, R430, R500, R510, R520
- Honeywell TDC 3000 — LCN, UCN, HPM, APM subsystems
- Honeywell PlantScape — Legacy installations
- Not compatible with Honeywell Safety Manager or ControlEdge series without engineering review
Selection Guide
Use the table below to select the correct module for your application:
- Need analog output (mA)? → MC-PHAO01

Replacement & Compatibility FAQ
Q: Can MC-PLAM02 replace MC-PHAO01 directly?
A: They serve different functions (mux input vs. analog output). Confirm your application requirement before substituting.
Q: Is MC-PSIM11 compatible with Experion PKS R520?
A: Generally yes for legacy I/O cabinets. Verify with Honeywell’s compatibility matrix or contact Konmask for engineering support.
Q: Do you supply refurbished units?
A: Yes. All refurbished units are tested and include a 12-month warranty. New surplus and factory-new options also available.
Q: What is the lead time for urgent orders?
A: Expedited shipping available for in-stock units. Contact us for same-day quotation.
Q: Can I return a module if it doesn’t fit my system?
A: Yes, within 30 days with original packaging and documentation. See our returns policy for details.
