Draw a diagram showing how this could be accomplished using an interposing relay. 2)Assume a thermocouple generates a linear voltage of from 20 mV to 50 mV when the temperature changes from 750°F to 1250°F. How much voltage will be generated when the temperature of the thermocouple is at 1000°F? 5)Assume the triac of an ac output module fails in the shorted state. How would this affect the device connected to this output?

Indicate which of LEDs marked X0 to X7 will turn on. 1.Explain why some of the input LEDs do not turn on as you touch the loose red wire to some of the input terminals of the PLC. 2.What needs to be done to enable those LEDs that did not turn on, to turn on as you touch the loose end of the red wire to corresponding input terminals? 3.Explain what you need to do to turn on LEDs X0 and X5 at the same time? 4.Explain what you need to do to turn on LEDs X0, X2, X4, and X6 at the same time? 5.For the software part of the lab answer the following questions: 6.Describe the operation of each instruction in each rung:
- 4. 7. Describe how you would modify the program so that when overheating occurs for the first time, the entire process stops. =============================================== ECET 405 Week 3 Chapter 4 Homework and Chapter 5 For more course tutorials visit www.tutorialrank.com ECET 405 Week 3 Chapter 4 Homework and Chapter 5 =============================================== ECET 405 Week 3 iLab For more course tutorials visit www.tutorialrank.com

Print a copy of the ladder logic program from your PC and attach to this worksheet. 3. Briefly describe the operation of each rung. The process starts by pressing the NO start pushbutton and can be stopped at any time by pressing an NC stop pushbutton. As soon as the process starts, a DC motor runs for five seconds and then stops. A LED blinks on/off for every second the motor runs. Once the motor stops, if the NO count pushbutton is pressed four times, the motor turns on again and runs for five more seconds. A LED blinks on/off for every second the motor runs. Then, the entire process ends. =============================================== ECET 405 Week 5 Homework For more course tutorials visit
