Application Fields:

• Upstream Exploration:
  Used for safety control of wellhead platforms, such as monitoring wellhead pressure and temperature, triggering emergency shutdown (ESD) when exceeding limits to prevent blowouts, leaks, and other accidents; controlling the valve switching logic of subsea production systems to ensure safety redundancy during the extraction process.

• Midstream Transportation:
  In long-distance pipeline stations, realizes rapid shutdown when pipeline pressure or flow is abnormal (such as triggering ESDV emergency shutdown valves) to avoid pipeline rupture; for natural gas compressor stations, monitors parameters like vibration and temperature to trigger interlock shutdown for equipment protection.

• Downstream Processing:
  Applied in process units of refineries and natural gas processing plants, such as over-temperature and over-pressure interlocks in catalytic cracking units, and emergency handling logic for gas leaks in desulfurization units, meeting SIL3 safety requirements.

• Hazardous Process Control:
  Serves as the core of safety interlocks in high-temperature and high-pressure reaction devices for ammonia synthesis, methanol, ethylene, etc. Monitors parameters such as reactor pressure, liquid level, and toxic gas concentration, and immediately cuts off feed and opens pressure relief devices when exceeding safety thresholds to prevent explosions or toxic substance diffusion.

• Pharmaceutical Compliance Production:
  Used in aseptic production environments for biopharmaceuticals to control the safe operation logic of key equipment (such as fermenters, sterilizers), ensuring production processes comply with GMP standards. It also triggers safe shutdown in case of equipment abnormalities to avoid batch scrapping or contamination.

• Thermal Power Generation:
  Applied to safety protection of boiler and steam turbine systems, such as interlock furnace shutdown and turbine shutdown control under conditions like abnormal furnace pressure and excessive drum water level; monitors gas turbine vibration and exhaust temperature to prevent equipment damage.

• Nuclear Power Auxiliary Systems:
  In non-nuclear safety systems of nuclear power plants (such as radioactive wastewater treatment, emergency ventilation systems), acts as the redundant control core to execute safety logic in support of safe operation of the nuclear island, meeting stringent seismic and environmental adaptability requirements.

• Protection of High-Temperature Metallurgical Equipment:
  In blast furnace and converter systems of steel plants, monitors furnace body temperature and cooling water flow, triggers emergency cooling or furnace shutdown interlocks to prevent equipment melting and leakage; controls the overload protection logic of rolling mills to avoid production interruptions caused by mechanical failures.

• Mine Safety Control:
  Used for safety interlocks of underground ventilation systems and hoists, such as automatically cutting off power and starting standby fans when gas concentration exceeds limits; controls the safe triggering logic of mine blasting equipment to ensure operational compliance.

• Railway Hub Safety:
  In railway marshalling yards and freight stations, controls the safety logic of turnout conversion and signal linkage to prevent train collisions; triggers emergency braking interlocks when abnormal track circuits are detected.

• Ports and Warehousing:
  Applied to loading and unloading equipment in dangerous goods terminals (such as oil pumps in crude oil storage tank areas), monitors risks like liquid level overflow and poor electrostatic grounding, triggers loading/unloading interruption and alarms, complying with maritime safety regulations.

• Papermaking and Food Processing:
  In pulping and cooking systems, controls the safety interlocks of high-temperature and high-pressure vessels; in food-grade aseptic filling lines, monitors product isolation logic when sterilization temperature is insufficient to ensure food safety.

• Water Treatment and Environmental Protection:
  Used for monitoring and interlocking toxic gases (such as hydrogen sulfide) in sewage treatment plants, triggering fan start/stop and personnel evacuation alarms; controls the temperature and pressure safety boundaries of hazardous waste incinerators to prevent excessive emission of harmful gases.
