Many thanks to those that replied... I am a systems programmer/analyst who knows just enough about electronics to be dangerous. So I appreciate the suggestions thus far. I think I will look into the "N-type, logic-level MOSFET rated to 20A" from WAYNEH on Mouser and see what I can dig up.
BTW, there are so many really awesome examples in the projects folders!
My question is this... I would like to use the output of an RS-232 signal (e.g., CTS/RTS for example) to drive a transistor that would open the flow of a 12 VDC 8 Amp supply. The RS-232 is TTL voltages. Would it be best to use a NPN or PNP circuit? What advice does anyone have and are there existing examples?
Thanks!!!!
