It is a combination of several relays and circuits in order to complement each others abnormal defects to achieve the complete and low -error -operated relays complete function, which makes the error and failure value.A variety of safety relays are designed to protect different levels of machinery, and the main goal is to protect the mechanical operators who are exposed to different levels.
Safety relay application
In rubber and plastic machines, there are many risk of fatal damage to operators or maintenance personnel.Quickly moved parts in tire manufacturing machines, such as mobile rings, tire removal, and supply racks, etc., will cause impact damage to the operating and maintenance people.In the injection molding machine, the template will cause squeezing damage to the operator and maintenance personnel.If an accident brings to the manufacturer, it is not just the loss of business compensation, but the huge potential threat caused by product output and workers fear of the industry. Therefore, safety devices must be used to reduce or avoid risks in such machines.
Types of security relays
Pilzpnozsigma compact safety relay.PNOZSIGMA Safety Reex with its smaller figure, more powerful functions, more flexible configurations, and more convenient diagnosis make us pay attention to it.Pnozmulti modular security relay.PNOZMULTI is a multi -functional, free configuration modular security system.Unlike other PNOZ security relays, the safety circuit of PNOZMULTI can be easily generated using a graphic configuration tool on the PC.PNOZELOG solid safety relay.The innovative PNOZELO series series is based on electronic technology and small design. It combines the advantages of traditional electromechanical PNOZ safety relay with modern electronics technology. Anti -wear, safe, long service life and high use of usageWise choice.PNOZPOWER high switching load security relay.The modular PNOZPOWER security system can be applied to emergency stop, security doors and grating monitoring.Pnozpower can switch up to 16AAC/DC current at each contact.Each module can have an overall switching ability of 40A.
Security relay brand
Siemens Safety Relay Electronics Electronics is extremely reliable and has a long service life.Siemens 3RS18 series interface relay should use the reset function of automatic and manual.Siemens 3UL22 series remaining current/leakage current monitoring current transformers can be used to detect fault currents in equipment and factories.Siemens 3UG4 series liquid level monitoring relay can also connect other resistance sensors to minimum and maximum values.
The role of safety relay
Safety relay is an automatic switch component with isolation function. It is widely used in remote control, telephone, communication, automatic control, electromechanical integration and electrical electronic equipment. It is one of the most important control components.
Safety relay working principle
Safety relays are composed of several relays and circuits in order to complement each others abnormal defects and achieve the complete and low -error -operated relay complete functions, making the error and failure value, and the higher the safety factors, the higher the safety factors.Therefore, a variety of safety relays need to be designed to protect different levels of machinery.The reason for use is a mechanical operator who protects exposure and different levels.
