With the rapid development of the electronic industry, relay module is more and more recognized by the market. At present, the relay module is known as the more popular electrical components in the market. When using the relay module, what should we pay attention to
1. DC relay should be controlled by rectangular wave as far as possible, and AC relay should be controlled by sine wave as far as possible.
2. The relay module should operate in the environment of normal temperature and humidity, with little dust and harmful gas. Only in this way can we report the operation process of the relay module, and the performance will not be affected by the environment
3. When the relay module is used, it must be set strictly according to the parameter standard in the manual.
4. The rated load and service life of relay module is an important reference. The performance and types of load will be different in different environments. Therefore, it is best to operate in the actual environment, so that problems can be found in the operation.
