Functions

Specific Application Fields

1. Emergency Shutdown System (ESD)
   • Connects field pressure/temperature sensors to ESD input modules, transmitting process parameter signals to the controller.
   • Connects ESD output signals to actuators like emergency shut-off valves and fire sprinkler systems, ensuring rapid safety actions during leaks, overpressure, etc.
2. Reactor Safety Interlock Control
   • Connects reactor temperature/pressure/level sensors to SIS input modules, transmitting data to the controller for logic operations.
   • Outputs control signals via terminals to safety valves and agitator emergency shutdown loops, preventing safety accidents from reaction runaway.
3. Thermal Power Plant Boiler Safety Control
   • Connects boiler water level gauges and superheater temperature sensors to SIS input modules for real-time key parameter monitoring.
   • Transmits signals via terminals to fuel shut-off valves and turbine emergency shutdown loops, preventing accidents like tube explosions and overpressure.
4. Renewable Energy (Wind/PV)
   • Connects vibration sensors in wind turbine towers and pitch system encoder wires, transmitting fault signals to the main control system.
   • Controls pitch motors and brake emergency shutdown via terminals to ensure equipment safety.
5. Rolling Mill Emergency Shutdown System
   • Connects rolling mill bearing temperature sensors and 跑偏 switches (deviation switches).
   • Triggers rolling mill main motor shutdown via terminals during equipment failures to avoid steel plate jams or mechanical damage.
6. Urban Natural Gas Distribution Network
   • Connects pipeline pressure sensors and flow transmitters to SIS, transmitting signals via terminals to pipeline block valves for automatic gas cutoff during leaks.
   • Integrates with SCADA systems for remote monitoring.
7. Rail Transit Signal System
   • Connects signal lights and switch position sensors beside train tracks to ensure reliable transmission and safety interlock of train operation signals.
8. Aerospace Ground Testing Equipment
   • Connects critical parameter sensors (pressure, temperature, etc.) to safety monitoring systems in rocket launch sites and spacecraft testing workshops, ensuring data collection and emergency shutdown control during testing.
