This research aims to present the system that to switch industrial loads using a user programmable logic control device for sequential operation. PLCs (Programmable logic controllers) used in industrial applications are very expensive for simple operations like sequential switching of loads. In this paper we demonstrate the working of this simple operation using a Raspberry Pi board which is a viable alternative for PLC. To develop this application requires programming through input key-buttons.In industries, there are many operations which requires some repetitive sequences in various orders and time intervals. For example, some loads need to be switched ON/OFF in specific time intervals. This method is proposed to switch the electrical loads sequentially by programmed instructions. Raspberry Pi module is programmed in such a way that the loads can be operated in three modes: Auto mode, Set mode and Manual mode. The status of loads by all modes are displayed on PC monitor or a TV.
