Function :<\/span><\/h1>\n

Time relays are designed for use in all areas where time dependent control is required.<\/span><\/p>\n

But first, we must know what the timer is (<\/span><\/strong> the electric timer) and what is it used in general?<\/span><\/h2>\n

The timer is one of the most important tools used in the field of electrical control, as it automatically connects a circuit after a specified period of time, to operate a load or to deliver electric current to a contactor coil. It is frequently used in control circuits, for the purpose of protecting the components of the drum.<\/span><\/p>\n

Components of the internal timer<\/span><\/h4>\n
    \n
  1. Timer feed source:<\/span><\/strong> \u00a0contains different voltages according to its manufacturer such as 220V\/AC or 120VA and so on.<\/span><\/li>\n
  2. Electronic board:<\/span><\/strong> \u00a0Its function is to control the specified time delay.<\/span><\/li>\n
  3. Rail:<\/span><\/strong> \u00a0Its function is one of the signals from the electronic board at the end of the time delay period, and accordingly the current reaches the relay coil, then the contact points of the relay are changed.<\/span><\/li>\n
  4. Indicator to control the time delay period.<\/span><\/li>\n<\/ol>\n

    <\/span>Timer contact points<\/span><\/h4>\n
      \n
    1. \u201cNormally Closed\u201d NC:<\/span><\/strong> \u00a0The points are in their normal state closed and open when the specified delay period ends. It can be used by placing a signal lamp to know the change of contact points from NC to NO.<\/span><\/li>\n
    2. \u201cNormally Open\u201d NO:<\/span><\/strong> \u00a0The points are in their normal state open and closed when the specified delay period ends.<\/span><\/li>\n
    3. Common point:<\/span><\/strong> \u00a0It is the common point, as it is directly connected to the electric current.<\/span><\/li>\n<\/ol>\n
