Industial automaation scada with plc

sir how to get input of and gate as u do in video and how to described by u ?..


in an AND Gates you have two switch in series connections. if first one is open/off and second one is close/on that time output not energize. similarly second one is off or first is on that time also output not energized. in an and gate when u using in practically use toggle switch either two way switch .
