SM1002 programmable safety controller

As the most important part of safety loop, safety controller/safety PLC has been recognized by more and more people, but in the process of use, there are still many users who are confused about the differences between safety relay and ordinary relay, so I would like to share them with you here. As we all know, we must remember three words in the concept of safety design:

(1) Redundancy

(2) Difference

(3) Self-detection

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.
