A PLC has eight inputs and eight outputs as shown in Figure 12.17(a). Draw a wiring diagram for this PLC that will be used as the controller for the situation of Exercise 3.
Figure 12.17(a)
Exercise 3
A small house has three windows and two doors. Each window and door has a switch attached such that the contacts close when a door or window opens. Draw a ladder logic diagram that will turn on a light if one or more windows are open or if both doors are open.
A finite state recognizer or sequence detector has one input (X) and one output (Z). The output is asserted high (Z=1) whenever the input sequence 1101 has been observed during the past four clock cycles, as long as 1110 has never been observed.
A Si sample is uniformly doped with phosphorus at 5 E 16 cm^-3. We make a p-n junction by implanting boron atoms into the surface layer. The implanted depth is 0.15 µm. What should the surface concentration of the boron implant
There are three different beams and they asked us to choose which beam would you use to build an object that incurs high stress. Should I choose the beam with the lowest deflection or with the highest deflection
Determine if the network is symmetric and if loss less - Determine the equivalent 2-port scattering matrix if port 3 is open-circuited
A wafer 100mm in diameter is mounted in an electron-beam evaporation system in which the spherical radius is 40cm. Use Eq. 6.7 to estimate the worst-case varation in film thickness between the center and edges
Find the transfer function of a second-order system that yields a 10% overshoot and a settling time (Ts) of 1.5s, plus tell the nature of the system
This will require two transformations from rectangular coordinates, one in the spatial domain and one in the frequency domain. There are two key transformations. Explain. Hint: This problem involves Bessel functions of the first kindof orders zero ..
(a) Calculate the radius of the orbit that would be perfectly circular under the Coulomb force. (b) Treat the electron as a current loop. Calculate the resulting torque when the electron-alpha system is placed in a magnetic field of 0.500 T direct..
For a mixture of ethane 60%, acetylene 20%, and benzene 20% total mass of 250 kg is loaded into a reactor obeying the Carnot cycle, we want to know which produces more work when reacted with 25% fuel, 60% O2, 15% CO2 for 30 cycles.
A painter is standing on a work platform that is 27 feet above ground level. For fall protection, the worker's safety harness D-ring is attached to a 12-foot shock absorbing lanyard that is securely fastened to the structure at a point 40 feet abo..
Assuming that the energy gap does not change with temperature, calculate the intrinsic electron concentration at the two temperatures. Look up the data for silicon that you need. Give your answer in carriers per cm cubed.
The figure shown below shows a one-line diagram of a simple power system containing a single 480 V generator and three loads. Assume that the transmission lines in this power system are lossless, and answer the following questions. Assume that..
