Application Scenarios of GE 8851-LC-MT

Safety Instrumented Systems (SIS) for Process Industries

Serves as the core logic control module of safety instrumented systems in various continuous process industries. It performs real-time monitoring, logic judgment and safety protection interlock for production process parameters, effectively preventing process deviation risks and ensuring the overall operational safety of industrial production lines.

Emergency Shutdown (ESD) Systems for Oil & Gas Industry

Widely deployed in oil and gas transmission pipelines, oil refineries, natural gas processing plants and upstream oilfield operation sites. It can quickly trigger emergency shutdown actions once abnormal working conditions such as overpressure, over-temperature and pipeline leakage occur, cutting off hazardous working conditions in time to avoid major safety accidents and equipment losses.

Fire and Gas Safety Control Systems for Chemical Plants

Applied to fire detection, flammable and toxic gas monitoring and linkage control systems in fine chemical, petrochemical and chemical raw material production plants. It realizes automatic alarm, ventilation start-stop, valve cut-off and other linkage protections for fire and gas leakage hazards, protecting personnel and factory equipment safety in hazardous chemical production areas.

Turbine and Boiler Safety Protection for Power Generation Plants

Used for safety interlock and protection control of core power equipment such as industrial steam turbines, gas turbines and power station boilers. It monitors equipment operating status in real time, executes high-speed safety response and fault shutdown logic, avoids equipment overload, failure and runaway operation, and guarantees safe and stable operation of power generation units.

Safety Interlock Control for Pharmaceutical Manufacturing Industry

Applied to safety protection of sterile production lines, reaction kettles, purification equipment and automated pharmaceutical production units. It complies with industrial safety and GMP production specifications, realizes stable safety interlock control during pharmaceutical production processes, prevents equipment failure and process risks, and ensures standardized and safe production.

Safety Monitoring and Shutdown Control for Metallurgical and Steel Mills

Suitable for safety monitoring and emergency interlock protection of high-temperature and high-risk equipment such as steelmaking furnaces, rolling mills and smelting equipment in metallurgical and steel enterprises. It monitors key operating parameters in real time, automatically triggers shutdown protection when abnormal risks occur, and reduces safety hazards in high-intensity industrial operation scenarios.

Process Safety Control for Water Treatment and Environmental Protection Facilities

Used for safety interlock and automatic control of large-scale sewage treatment equipment, industrial wastewater treatment systems and environmental protection discharge facilities. It ensures the stable and safe operation of water treatment process equipment, avoids equipment failure causing environmental discharge risks, and supports standardized and safe operation of environmental protection facilities.

Redundant Safety Network Communication for Long-distance Industrial Sites

Relying on dual redundant optical fiber Ethernet communication design, it provides stable, high-speed and anti-interference safety data transmission for long-distance distributed industrial sites such as remote chemical parks, pipeline stations and scattered industrial equipment. It solves the problem of signal attenuation and unstable communication in long-distance industrial transmission scenarios.

SIL-certified Safety Logic Execution for Hazardous Area Control

With SIL2 safety integrity level certification, it is applicable to safety logic operation and automatic control of flammable, explosive and high-risk hazardous industrial areas. It provides high-reliability safety judgment and execution capabilities for hazardous area control systems, meeting strict industrial safety standard requirements.

Event Recording and Fault Diagnostics for Critical Process Assets

Supports mass event data storage and real-time system fault diagnosis, applied to operation monitoring, data recording and post-event analysis of core and critical industrial process equipment. It helps engineering personnel quickly locate equipment faults, sort out operation problems, and realize intelligent operation maintenance and safety management of production assets.
