Abstracts: PLC system has become a vital part of instrumentation engineering in modern era. This system is being used in power plant, packaging industries, car assembly and many more. Being an Instrumentation engineering student, we want to design and learn such system. Ultimately we want to design an Automatic Rejection System using PLC. In which with the help of Load Cell we are going to measure weight of the given object. A conveyer belt is used to roll down the object under the sensor. The sensor sense the object’s weight and if it satisfies the set value than it will proceed further else it will reject it. The rejection will be done by the lever which is placed side above the conveyer belt. The most interesting thing in the project is that all the procedure is based on PLC and we can change set point of weight manually for each every object procedure. It is mostly used in every manufacturing industries.
