and output,power supply)The micro controlled ICs power
ratiing 5volt/4ma ie Plc is the power rating 12volt,24volt,
48volt etc.micro controlled ICs power ratiing 5volt/4ma is
converted the corresponding plc 12volt,24volt, 48volt
etc.plc input is conneced the computer and the output is
logically operated ie on or off conditions.ie
relay,optocoupler,magnetic proximity switches
connecting.Plc of the lader logics loded through computer
