Posted 19 Feb 2018 Hey, I would like to build a plc system for a residential elevator. I wanted to secure the code and was thinking of a chip based plc on a board with inputs outputs and input for encoder. Anyone here know where I can get a less expensive system like this around $200? Maybe sourced from China? Share this post Link to post Share on other sites
