Mechanical safety is a complex system engineering, which needs to consider many factors, such as mechanical equipment characteristics, process operation characteristics, safety design concept and so on.

 In general, The safety control system shall include safety b equipment (such as emergency stop button, safety threshold switch or interlock switch, safety grating or light curtain, two hand control button), safety control electrical components (such as safety relay, safety PLC and safety bus) and safety output control (such as contactors, relays or valves in the main circuit). Among them, safety PLC is a product that deserves special attention in application. The so-called safety PLC is a PLC specially designed for harsh tasks or safety related applications. In case of failure, it will not bring danger to personnel safety or process safety. 

A safety PLC has achieved specific reliability / fault probability according to requirements Rate level means that it has a wide range of self diagnosis ability, and can monitor all aspects of hardware status, program execution status and operating system status. In addition, The safety PLC must also be able to perb the necessary fail safe bs certified by standard institutions (such as TUV, FM, etc.), and these fail safe bs are designed according to specific principles and meet international safety standards (such as IEC61508 and en954-1, etc.). In addition, the safety PLC may also include security protection early warning and authority management to protect the safety PLC from external interference.
