introduction：Relays have the following basic precautions in use： 1)The use of relays should be combined with the various parameter ranges listed in the product manual as far as possible 2)Rated load and life are a reference value，It depends on different environmental factors、The nature and type of load are quite different，Therefore, it is best to confirm in real or simulated real use。 3)Dc relays use rectangular wave control as much as possible，Ac relays use sine wave control as much as possible。 4)To maintain the performance of the relay，Be careful not to let the relay drop or be subjected to strong shocks。Outdated relays are not recommended for use。
