    Input 6 on the diagram is probably the relay input pin. In order to activate it (Active High) the value across the capacitor would have to reach a HI input level, but the capacitor/Resistor combination takes time to charge to that level. time constant for such a series R/C connection is \[\tau = RC\]

    By adjusting the resistive value you can prolong/shorten the time required to reach an active HI level

    Relays perform the sensing and actuating function on any abnormal condition so the relay which provides the abnormal condition signal after a specific time interval is called Time delay relay...
