Scope: This part of GB 30439 specifies the protection against electric shock and electric burns, mechanical hazards, flame spreading from the inside of the loop regulator to the outside, overheat protection, fluid and fluid pressure influence, explosion and internal control for circuit regulators in industrial automation products. Explosive security content. This part does not cover functions, performance or other characteristics of equipment not related to safety, effectiveness of transport packaging, electromagnetic compatibility (EMC) requirements, functional safety, protection against explosive atmospheres, maintenance (repair), maintenance (repair) personnel protection. Products specified in this section are not intended for use in corrosive environments. If the loop regulator product is to be used in other environments (such as buildings, medical, etc.), the loop regulator product must also meet the special requirements, standards and installation guidelines applicable to the corresponding environment. This part is applicable to regulating instruments in the industrial production process, the signal is an electrical signal, used indoors, the power supply voltage is below 300 V and has a control output signal. This section does not apply to devices that are integrated with sensors and whose input signals are physical quantities (such as: bimetallic temperature controllers).
