Advantages & Features

1. Redundant Dual-Core Architecture: HONEYWELL CC-TCF901 employs a hot-standby 1oo2 redundant design with dual-core processing, ensuring seamless failover (<50ms) and uninterrupted control logic execution—critical for continuous-process industries like refineries and chemical plants.
2. High-Speed Processing Performance: With an 800MHz dual-core processor and ≤1ms control cycle time, HONEYWELL CC-TCF901 executes complex control algorithms and safety interlock logic in real time, enabling rapid response to process anomalies.
3. SIL Certification & Hazardous Environment Compliance: Certified to IEC 61508 SIL 2/SIL 3 and ATEX/IECEx Zone 2, HONEYWELL CC-TCF901 meets the safety requirements of critical applications and can operate in explosive environments without additional protection.
4. Scalable I/O & Communication Support: The module supports up to 8192 digital and 2048 analog I/O points, with multi-protocol communication interfaces (FTE, Ethernet/IP, OPC UA) to integrate with legacy and modern devices, ensuring system scalability for future expansion.

Application Fields & Cases

1. Oil Refinery Central Control System: A major oil refinery deployed HONEYWELL CC-TCF901 as the core processor for its Experion PKS system, controlling crude distillation, catalytic cracking, and product blending units. The redundant architecture prevented unplanned downtime during a primary processor failure, maintaining continuous operation of critical processes.
2. Chemical Plant Batch Process Control: A petrochemical plant integrated HONEYWELL CC-TCF901 into its TPS system to manage multi-product batch reactors, executing complex sequence control logic and safety interlocks. The module’s fast cycle time enabled precise control of reaction temperatures and pressures, reducing product waste and improving process efficiency.
3. Power Plant Boiler & Turbine Control: A combined-cycle power plant used HONEYWELL CC-TCF901 to control boiler combustion systems and turbine generators, with SIL 3 certification supporting safety interlocks for overpressure and overspeed protection. The module’s diagnostic capabilities detected a memory error early, allowing proactive maintenance before system disruption.

Competitor Comparison

Selection Suggestions & Precautions

1. Selection Suggestions: HONEYWELL CC-TCF901 is ideal for Honeywell Experion PKS/TPS users requiring a redundant, high-performance processor for medium to large-scale control systems (e.g., refineries, chemical plants with safety-critical processes). For Emerson DeltaV users, Emerson’s DeltaV Controller is preferred; Siemens S7-400H CPU suits TIA ecosystem users with smaller I/O requirements.
2. Precautions:
   • Ensure redundant power supplies are connected to independent sources (main grid + UPS) to maintain hot-standby functionality and prevent common-mode failures.
   • Use shielded Ethernet cables for FTE connections to minimize EMI interference and ensure reliable communication with I/O modules.
   • Regularly back up control logic configurations to flash storage or external media to prevent data loss in case of memory corruption.
   • Test redundancy failover (quarterly) by simulating a primary processor failure to verify seamless switchover and validate system continuity.
   • Update firmware only during scheduled maintenance windows to avoid disrupting critical processes, and follow Honeywell’s official firmware update procedures.
