How to construct the safety loop with the reliability above PLd, the safety controller must become an important link. The safety loop consists of safety input, safety control and safety output subsystems, and the safety control "including safety relay, safety controller, safety PLC, etc." realizes the safety control function. Designers match different safety controllers to achieve the reliability level of the safety loop according to the number of products at the input end.
