    Need to convert equations to practical circuits.

    Hi, I have an electrical engineering degree and I know some very basic techniques to convert design equation into working prototypes but I want to learn this at an advanced level. I don't have the time to start a pHD program so I have to learn synthesis on my own. Can someone recommend some...

    Is there software to process and/or simplify boolean logic.

    I use boolean algebra to simplify my motor and lighting control designs. I normally do it by hand but it would be nice if I had a software program that made the task easier. The way I use boolean algebra is what used to be called switching logic. I don't know what is called nowadays but I think...

    24 V control for mechanically held AC lighting contactor.

    Thanks to both skogsgurra and waross. I'll study the alternatives you give and make a decision.

    24 V control for mechanically held AC lighting contactor.

    I have installed a Square-D, class 8903, Type LX, mechanically held lighting contactor. A Methasis panel supplies one control signal. The problem is that this contactor requires two signals, one to latch and one to unlatch. I have been unsuccessfully looking for a multiplexer that can route the...

    Books on logic design using relays and timers?

    itsmoked: Traditionally, motor control logic is shown in terms of ladder diagrams. I know how to design using digital logic gates such as AND, OR, J-K flip-flops, and the like. My problem now is that I am trying to design circuits that perform the same function as logic gates using contacts...

    Books on logic design using relays and timers?

    I have been unsuccessful in finding any books that describe the process of designing motor control ladder logic. I took several Digital Logic Design classes. Neither one included logic using the variety of contacts and timers available. Rather than reinventing the wheel, I'd like to read a book...
