Relais 12v manufacturers analyze the basic principle of relais 12v action

However, the sensor detection system needs a delay time after receiving the input data signal, and then the system software will execute the action to output the data signal, thereby controlling the home appliance of the control loop is called time relais 12v. It is commonly used to manipulate the technological process formulated according to time standards in the production process. There are many types of time relais 12v, the common ones are inductive, electric, gas damping, and transistor type.

Most of the relais 12v actuators are all contact system software. According to the "on" and "off" of the relais 12v accessories, a certain manipulation function can be performed. Common faults of contact system software generally include contact over-temperature, damage, and arc welding. The key reason for the overtemperature of the contact is insufficient volume, insufficient contact working pressure, surface air oxidation or not cleaning, etc.; the key reason for aggravated damage is that the contact volume is too small, and the temperature of the electrical isolation is too high to make the contact metal material air. Oxidation, etc.; the key reason for arc welding of the contact is that the temperature of the electric isolation is too high, or the contact is more vibrating. The maintenance sequence of the contacts is as follows:

    (1) Open the rear cover and check the surface condition of the contacts.
    (2) If the surface of the relais 12v contact is air oxidized, the silver contact will not be repaired, and the copper contact can be filed with a shiny file or gently scraped off the air oxide layer on the surface with a fruit knife.
