The electrical upgrade of the green carbon facility at the aluminum plant was complete. A myriad of programmable logic controllers (PLCs) and PC-based graphic user interface (GUI) systems replaced the ...
In Part 1 of this two-part series, we explored PLC basics and voltage sag susceptibilities. In this segment, we present PLC voltage sag test results along with guidelines for making PLC systems more ...
This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...
