Process Automation & Redundant Control Solution – Honeywell 2MLR-CPUH/F-CC | MasterLogic ML200 Series
Where This Product Is Used
The Honeywell 2MLR-CPUH/F-CC is the redundant CPU module at the heart of the MasterLogic ML200 Distributed Control System (DCS). It is engineered for mission-critical continuous process environments where unplanned downtime is unacceptable. Typical deployment sites include:
- Oil & Gas – Upstream wellhead automation, midstream pipeline SCADA, downstream refinery unit control
- Petrochemical & Chemical Plants – Reactor temperature/pressure loop control, batch sequencing, safety interlock integration
- Power Generation – Boiler management systems (BMS), turbine governor control, balance-of-plant (BOP) automation
- Pulp & Paper / Water Treatment – Continuous process lines requiring hot-standby redundancy and bumpless switchover
- Pharmaceutical Manufacturing – FDA 21 CFR Part 11 compliant batch control with full audit trail
The /F-CC suffix designates the Fail-safe, Controller-to-Controller communication variant, enabling tight coupling between redundant CPU pairs for sub-millisecond switchover without process upset.

Why Engineers Specify This Model
- True Hot-Standby Redundancy – The /F-CC variant synchronises memory state between primary and backup CPUs in real time; switchover is transparent to field devices and HMI operators.
- Fail-Safe Architecture – Integrated safety logic meets IEC 61508 SIL requirements, reducing the need for a separate safety PLC in many applications.
- Deterministic Scan Cycle – Fixed-cycle execution ensures predictable loop performance for tight PID and cascade control strategies.
- Seamless Honeywell Ecosystem Integration – Native compatibility with Experion PKS, UniSim, and Honeywell FDM for unified asset management.
- Long Product Lifecycle – Honeywell’s extended support commitment protects capital investment in brownfield DCS installations.

Application-Specific FAQ
Q: Can the 2MLR-CPUH/F-CC replace a non-redundant 2MLR-CPUH in an existing ML200 system?
A: Yes, provided the rack and power supply support redundant operation. A firmware upgrade may be required — contact us for a compatibility check.
Q: What is the maximum number of I/O points supported per CPU?
A: The ML200 CPU supports up to 2,048 digital and 512 analogue I/O points per controller node in standard configuration.
Q: Is the /F-CC variant required for SIL-rated loops?
A: The Fail-safe (/F) designation is required for SIL 1/2 loop certification. The C-C suffix adds CPU-to-CPU redundancy; both are recommended for high-availability safety applications.
Q: How long is the typical lead time?
A: In-stock units ship within 3–5 business days. For sourced units, lead time is 2–4 weeks depending on availability.
Q: Do you provide a test report?
A: Yes. A functional test report is available for all refurbished and tested-used units at no additional charge.
