introduction:Safety relay wiring diagram The safety relay is to make a regular action when the fault occurs,Safety relay There is a forced guide contact structure,It also ensures safety in case of contact fusion,This is completely different from the general relay。According to the EUEN 50205Standard,The forced guide contact consists of at least one normally open and normally closed contact。Fully forced guide contact in case of adhesion of any contact,The linkage contacts must be kept normally open. All contacts must use a forced break structure to achieveClass AApplication standard,To adopt a dedicated logo。Below, Feng Yes small edition will take you to understand the wiring diagram of the safety relay!
