Compatible Replacement & Equivalent Models
When the Honeywell 2MLK-CPUH-CC is unavailable or discontinued, the following models may serve as direct or functional replacements depending on your system configuration. Always verify firmware compatibility and backplane slot requirements before substitution.
- Honeywell 2MLK-CPUH – Base CPU variant without CC interface; suitable if controller communication port is not required
- Honeywell 51304485-100 – Alternative CPU module used in compatible Honeywell controller racks
- Honeywell 51304485-150 – Enhanced revision with extended memory; drop-in compatible in most configurations
- Honeywell MC-PAOX02 – Functionally equivalent CPU for Experion-integrated systems
- Third-party compatible CPUs – Contact Konmask for vetted cross-reference options that meet OEM specifications
Note: Replacement compatibility depends on firmware version, rack type, and system software. Konmask engineers can assist with cross-reference validation.
Why Choose the Original Model
- OEM Guaranteed Compatibility: The 2MLK-CPUH-CC is factory-tested and certified for Honeywell Modular Controller racks — no firmware patching or workarounds required.
- CC Interface Integrity: The integrated Controller Communication port ensures native peer-to-peer and supervisory network connectivity without additional adapters.
- Long Service Life: Honeywell industrial modules are engineered for 10+ year operational lifespans in demanding environments.
- Regulatory Compliance: Original modules carry full CE/UL documentation, critical for regulated industries such as oil & gas, pharmaceuticals, and utilities.
- Reduced Integration Risk: Using the original part eliminates compatibility unknowns and simplifies system validation and FAT/SAT testing.
Typical Applications
- Process automation in oil & gas refineries and petrochemical plants
- Power generation and utility distribution control systems
- Pharmaceutical batch processing and clean-room automation
- Water and wastewater treatment plant SCADA integration
- Chemical plant distributed control system (DCS) upgrades
- Building management and HVAC central control
- Food & beverage production line automation
System Compatibility
- Compatible Racks: Honeywell Modular Controller backplane racks (2-slot, 4-slot, 8-slot configurations)
- Compatible I/O Modules: All 2MLK-series analog and digital I/O modules
- Programming Software: Honeywell Control Builder, compatible with IEC 61131-3 structured text and ladder logic
- Communication Protocols: Modbus RTU/TCP, HART, OPC-UA (via gateway), Ethernet/IP
- Power Supply: Compatible with standard Honeywell 24 VDC rack power supplies
Selection Guide
Use the following criteria to confirm the Honeywell 2MLK-CPUH-CC is the right choice for your project:
- Step 1 – Verify Rack Type: Confirm your backplane is a Honeywell 2MLK-series rack. The CPU must match the rack’s bus architecture.
- Step 2 – Check Communication Requirements: If your system requires controller-to-controller (CC) communication, the “-CC” suffix is mandatory. Without it, select the base 2MLK-CPUH.
- Step 3 – Confirm Firmware Version: Match the CPU firmware to your existing I/O modules and programming software version to avoid compatibility issues.
- Step 4 – Assess Memory Needs: For large programs (>1 MB logic), consider higher-memory CPU variants or contact Konmask for guidance.
- Step 5 – Evaluate Redundancy: For critical processes, pair with a redundant CPU module and hot-standby power supply for fault-tolerant operation.
