Induction motor is the most widely used alternating current (AC) motor and can be found in every industrial application such as pumps, belt conveyors, and others. Induction motors holds significant in meeting these needs and induction motors have several advantages, namely simple construction, relatively cheaper prices, and easier motor maintenance than other motors. In the industrial world that is experiencing a significant development in both large and small industries. This is where the need for production equipment is very necessary to support the continuity of production. Production equipment is indispensable in increasing time and cost efficiency. Electric motors are needed in the industrial world as the main means of locomotion. Smart relay zelio is a tool that can be programmed using a ladder diagram or FBD (Function Block Diagram) that can be used for the automation process. The purpose of creating a smart relay zelio is to replace the logic of working on a relay control circuit which is a direct installation. By using this smart relay, the control circuit that previously used relays will be much simpler.} }
