Can a 50-Hz designed transformer be used at 60-Hz system? Is the same remains true, when a 60-Hz designed transformer be used at 50-Hz system? Consider only frequency variation. The voltage remains as rated value in all cases. Justify the answer.2 5100
Hello, im taking an introduction to PLC..and i'm having a hard time on creating a program for 2 lamps blinking alternately with this button characteristics: 1.) One push button (starts upon pressing) 2.) Same push button (when pressed again, will pause the system) 3.) Same push button (when pressed again, will continue the paused system) 4.) Same push button (when pressed within 2 seconds, will shut off the system) Pls..i know this is just a simple problem for you guys..2 1717
