Abstract: - In most of the industrial processes it is required to rotate DC (or AC) motor forward and reverse for desired time. First motor rotates forward (clockwise) for some time (say 2 3 min) then it stops for some time. Again it rotates reverse (anticlockwise) for some time and rests. This process repeats every time when gets triggered.

For example, in automated bottle filling plant, the bottles are moving on conveyor belt. When it comes under filler, the filler comes down (that means motor attached with mechanism rotates forward) then ....etc

Sequential device activator or process control timer circuits have wide area of applications and its complexity varies depending upon the device to be activated. Here is a simple sequential device activator circuit using IC 555 and relay as activator. As we all know that IC555 has some unique capabilities to act as a timer and oscillator. Here we employ the IC 555 as a timer to activate three device sequentially given specific timings for each device. The main advantage of this circuit is you can increase the number of devices to be activated j ....etc
