Compatible Replacement & Equivalent Models
When the 2MLR-CPUH/S is unavailable or end-of-life, the following models may serve as functional replacements or equivalents depending on your system configuration. Always verify firmware compatibility and safety certification before substitution.
- Honeywell 2MLR-CPUH — Non-redundant variant; same processor family, reduced HA capability
- Honeywell SM-CPU — Safety Manager CPU series; confirm slot and backplane compatibility
- Honeywell FC-SDNM-0001 — Safety network module; used in conjunction with CPU upgrades
- Triconex 3008 / 3009 (Schneider Electric) — SIL 3 TMR CPU; cross-platform alternative for safety PLC migration
- HIMA F3 MIO 12/8 01 — HIMax safety CPU; suitable for greenfield SIL 3 projects
⚠ Note: Cross-brand replacements require full system re-validation. Consult your safety engineer before substitution.

System Compatibility
The 2MLR-CPUH/S is designed for use within the Honeywell Safety Manager platform. Confirm compatibility with the following system components before ordering:
- Backplane / Chassis: Honeywell Safety Manager I/O chassis (2MLR series)
- Power Supply: Honeywell 2MLR-PS series
- I/O Modules: 2MLR-series digital/analog I/O modules
- Engineering Tool: Safety Builder (SB) software — version compatibility must be verified
- Network: Honeywell Safety Network (HSN) or Ethernet-based safety bus
Selection Guide
Use the following criteria to determine if the 2MLR-CPUH/S is the right module for your application:
- Redundancy Required? → Choose 2MLR-CPUH/S (redundant) over 2MLR-CPUH (simplex)
- SIL Level? → SIL 2 minimum; SIL 3 with validated redundant configuration
- Existing Platform? → Must be Honeywell Safety Manager; not compatible with Experion PKS or ControlEdge
- Firmware Version? → Confirm Safety Builder version supports your target firmware
- Spare or Replacement? → Verify part revision (Rev A/B/C) matches installed base

Replacement & Compatibility FAQ
Q: Can I use 2MLR-CPUH instead of 2MLR-CPUH/S?
A: The 2MLR-CPUH is the simplex (non-redundant) variant. It can be used in non-redundant configurations but does not support hot-standby CPU failover.
Q: Is the 2MLR-CPUH/S still in production?
A: Honeywell has transitioned some Safety Manager components to newer platforms. Contact us to confirm current availability and any recommended upgrade paths.
Q: Can this module be used in Experion PKS?
A: No. The 2MLR-CPUH/S is specific to the Safety Manager platform and is not compatible with Experion PKS or ControlEdge architectures.
Q: Do you provide test reports or certificates of conformance?
A: Yes. Certificates of conformance and inspection reports are available upon request for qualified buyers.
Q: What is the lead time?
A: Typically 3–10 business days for in-stock units. Custom sourcing may require 2–4 weeks.
