  • Chapter 7 TIMERS, COUNTERS and T/C APPLICATIONS
    Chapter 7 TIMERS, COUNTERS and T/C APPLICATIONS Introduction Timers and counters are discussed in the same chapter since most rules apply to both. Timers and counters have been in existence for as long as relays and provide an important component in the development of logic. Timers were constructed in the past as an add-on device to relays slowing down the transition of the plunger from immediately opening or closing. The time delay was accomplished with a pneumatic bladder that allowed the air to escape either quickly or slowly depending on the setting of the timer. Quick was usually less than a second and slow was usually between 30 and 60 seconds. Setting this kind of timer was an inexact science and today's traffic lights are an example of the fickle nature of timers that seldom respond in exactly the same from day to day and year to year. For the first time, function blocks are introduced in the rung output position or coil position to provide timer and counter functions. Function blocks allow inputs from the left and pass power through to the right when the function is done or when various conditions are met. Either the timer has timed out or the counter has counted to the preset. Function block usage differs from manufacturer to manufacturer. Function blocks rely on a standard format to enter information about the counter or timer. All variables in the function block must be entered correctly before the device will operate. Some timers are referred to as retentive. Retentive refers to the device’s ability to remember its exact status such that when the circuit is again activated, the timer continues from the previous point.

  • Digital Electronics: Logic and Clocks
    DIGITAL ELECTRONICS: LOGIC AND CLOCKS LAB 9 INTRO: INTRODUCTION TO DISCRETE DIGITAL LOGIC, MEMORY, AND CLOCKS GOALS In this experiment, we will learn about the most basic elements of digital electronics, from which more complex circuits, including computers, can be constructed. Proficiency with new equipment and approaches: o Logic gates, memory circuits, digital clocks o Combining components & Boolean logic DEFINITIONS Duty cycle – percentage of time during one cycle that a system is active (+5V in the case of digital logic) Truth table – table that shows all possible input combinations and the resulting outputs of digital logic components Flip-flop - a circuit that has two stable states and can be used to store state information. Logic gates – a physical device that implements some Boolean logic operation DIGITAL CIRCUITS - GENERAL In almost all experiments in the physical sciences, the signals that represent physical quantities start out as analog waveforms. To display and analyze the information contained in these signals, they most often are converted into digital data. Often this is done inside a commercial instrument such as an oscilloscope or a lock-in amplifier, which is then connected to a computer through a digital interface. In other cases, data acquisition cards are added to a computer chassis, allowing analog signals to be input directly to the computer. Scientists usually buy their data acquisition equipment rather than build it, so they usually don’t have to know too much about the digital circuitry that makes it work. Almost all data are eventually analyzed digitally with a computer. Analog information can be translated into digital form by a device called an Analog-to-Digital Converter (A/D converter or ADC).

  • 0 to 60 Hour Start / Stop Timer
    Total solder points: 96 + 43 Difficulty level: beginner 1 2 3 4 5 advanced 0 TO 60 HOUR START / STOP TIMER K6200 Broad range mains operated start / stop timer. ILLUSTRATED ASSEMBLY MANUAL H6200IP-1 VELLEMAN NV Legen Heirweg 33 9890 Gavere Belgium Europe www.velleman.be www.velleman-kit.com Features & Specifications If you want to have a device switched off after a given time, then this timer is the device you are looking for. Thanks to its big range this timer can be installed just about everywhere, for switching off your TV and HI-FI, the lights in the stairwell, as a security timer for your automatic coffee-maker, as a dark room timer, for mak- ing a short chime signal... etc. For the latter application you can control the start/stop timer from a switching clock such as the K6000 for example. The rough setting (from a couple of seconds up to about 20 hours) is done using dip switches, while the fine tuning is achieved by turning a trimming potentiometer. The timer has push buttons for starting and untimely stopping and it further allows to control the circuit by relay or open collector (e.g. our 15 channel remote controlled receiver K8050). The circuit can be fed directly from the mains and is so compact that it fits in a standard adapter housing. Features: Relay output: 5A at 220V LED indication Setting range: from +/- 3 secs to +/- 60 hours Starts promptly when the start push button is pressed Can be operated from an external push button or relay Can be operated from an open collector output (*) Power supply: 24VAC/50mA, 220VAC.

The strategic release planning is gotten from the concept of how a door machine with password access functions. In this thesis project, all that has been studied in school such as circuit theory, electronics, digital design and microprocessors basic and programming course are combined to the success of this project. Therefore the objective is producing a practical knowledge of what has been studied which is the timer with password access. The method used was an inspiration gotten after reviewing many materials in some respective topic related to designing a timer. The particular method comes from creating an SPI Interface from the Programmer to the Microcontroller to Make Transferring More Convenient. The performance of the MCU, LCD and keypad was just as was expected in the software code and hardware also. The password is inputted, timer is set appropriately and timer runs till port is opened. To conclude, the result can be achieved in different method but this method was for an easy method for beginners.

    Electronic Instrumentation ENGR-4300 Fall 2006 Experiment 7 Experiment 7 Digital Logic Devices and the 555 Timer Purpose: In this experiment we address the concepts of digital electronics and look at the 555 timer, a device that uses digital devices and other electronic switching elements to generate pulses. Equipment Required: • Voltmeter (Rensselaer IOBoard) • Oscilloscope (Rensselaer IOBoard) • Function Generator (Rensselaer IOBoard) • +5V Power Supply (Rensselaer IOBoard) • 555 Timer IC Helpful links for this experiment can be found on the links page for this course: http://hibp.ecse.rpi.edu/~connor/education/EILinks.html#Exp7 Part A – Basic Logic Gates Background Digital logic gates: All digital logic gates are based on binary logic. Binary logic has two values, called TRUE and FALSE or LOGIC 1 and LOGIC 0 or ON and OFF or HIGH and LOW. The corresponding binary number can have two possible values, 1 and 0. Digital logic gates perform many common logic operations on binary signals, such as AND, OR, NOT, NAND, and NOR. The table in figure A-1 contains the common symbol for each type of gate, an expression for the function of the gate in Boolean algebra, and a truth table for the device. The truth table shows how the gate will behave for all possible combinations of digital inputs. K.A. Connor, Susan Bonner, and Schoch 1 Revised: 10/27/2006 Rensselaer Polytechnic Institute Troy, New York, USA Electronic Instrumentation ENGR-4300 Fall 2006 Experiment 7 Figure A-1 Figure A-1 (continued) Digital logic chips: In TTL digital electronic circuits, the representation of binary numbers in terms of voltages is about 5 volts for LOGIC 1 and about 0 volts for LOGIC 0.
