Anything To Replace A PLC (programmable logic controller)device? Hi can anyone recommend me with a device that funtions like a PLC but is cheaper.I need to use it to run a fan according to different voltage levels and scrap the use of the stepper motor. Can anyone reccomend me with any device and the website to the product would be good. Thank you so much

Please do reply if u have any clue about the same. Also If possible please let me know where I will get the block daigram of PLC. Thanks in advance

Hi guys, Im a bit confuse about the main difference between cnc and "custom automated system using plc ". Is my statement correct : plc and cnc applications are the same where both are automation processes.
