Advantages & Features

1. Top – tier Safety & High Reliability: With SIL 3 certification, HIMA F35 uses a triple – redundant CPU channel design and “two – out – of – three” voting logic. This structure minimizes the risk of dangerous failures, and its average probability of dangerous failure per hour (PFHD) is lower than 10⁻⁹/h, meeting the strictest safety needs of critical industrial processes.
2. Flexible Integration & Multi – protocol Support: HIMA F35 is compatible with both safety protocols such as PROFIsafe and general protocols like Modbus TCP. It has a built – in protocol conversion engine, which allows it to simultaneously process safety and non – safety data, greatly simplifying the complexity of system integration in mixed – protocol industrial sites.
3. Convenient Maintenance & Diagnostic Capabilities: The hot – swappable module design of HIMA F35 enables engineers to replace components without shutting down the entire system. Its built – in BIST technology achieves 99.9% hardware fault coverage, and it can upload equipment status data to the cloud via OPC UA for remote health monitoring.
4. Wide Environmental Adaptability: It can operate stably in extreme environments with temperatures ranging from -40°C to +70°C and has strong anti – electromagnetic interference ability compliant with EN 61000 – 6 – 2 standards. Some variants are designed for subsea use, complying with ISO 13628 – 6:2006 standards.

Application Fields & Cases

1. Oil Refinery Emergency Shutdown System (ESD): A large oil refinery adopted HIMA F35 to build its crude distillation unit’s ESD system. The controller monitored pipeline pressure and temperature in real time. When an overpressure anomaly occurred, it triggered the emergency shutdown valve within 5ms, preventing crude oil leakage and avoiding a major safety accident.
2. Nuclear Power Plant Auxiliary Equipment Control: A nuclear power plant used HIMA F35 to control its reactor auxiliary cooling and gas detection systems. The controller’s redundant design and low false alarm rate ensured that the auxiliary systems could respond accurately during abnormal conditions, and its long – term stable operation met the nuclear industry’s strict reliability requirements.
3. Chemical Plant Burner Management System (BMS): A petrochemical plant integrated HIMA F35 into its reactor burner management system. It monitored the ignition status and flame temperature of the burner. When an abnormal flameout occurred, it quickly cut off the fuel supply. Its compatibility with PROFIBUS DP also realized seamless data interaction with the plant’s central control system.

Competitor Comparison

Selection Suggestions & Precautions

1. Selection Suggestions: HIMA F35 is the preferred option for users who need a compact SIL 3 safety controller in process industries such as oil & gas and chemicals, especially those using HIMA’s HIMatrix distributed systems. For users focused on discrete manufacturing and requiring close integration with general – purpose automation systems, Siemens S7 – 1500F may be more suitable. For projects relying on Rockwell’s equipment ecosystem, Rockwell GuardLogix 5580 is a better fit.
2. Precautions
   • Select the appropriate variant (e.g., subsea – specific F35 012) according to the operating temperature and environmental conditions of the application site.
   • Ensure the system firmware is compatible with HIMA SILworX or ELOP II programming tools to unlock full functionality.
   • Avoid overloading the I/O channels and strictly match the load parameters with the controller’s rated I/O specifications.
   • Regularly check the diagnostic data uploaded by the controller to handle potential power or communication faults in a timely manner.
   • Use shielded cables for communication wiring to enhance anti – electromagnetic interference capability and ensure stable signal transmission.
