What are the uses of plc's?
PLC stands for Programmable Logic Controller. It is a computer that controls/automates industrial machinery and equipment by monitoring inputs, and controlling outputs based on what the program running on the PLC tells it to do. Examples of inputs: tachometers, switches, thermostats, etc. Examples of outputs: lights, horns, high voltage contacts for switching motors on and off, etc. PLC's are used to control amusement park rides, conveyor systems, and most industrial equipment found at production lines, mills, etc. A PLC can be used to control/automate virtually any piece of equipment or machine.
What are the uses of counters to logic circuits?
counters are used to store, display or sometimes count the pulses in a circuit.
What is TTL logic family?
To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster. TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed. = In TTL (Transistor-Transistor Logic), think that the device using this technology is made from several transistors. Another advantage is that many more chips employ this technology.
What devices uses anolog signals?
Generally process control devices use analog signal. Normally in an industrial automation setup, 0-20 mA (mili amp) or 4-20 mA or 0- 10 Volts are used. These signals are used for both providing control output and to provide feed back signal (say to a PLC (programmable logic controller) or DCS) Example for a control out put is a motorized damper operated by 4 - 20 mA signal. PLC provides 4-20 ma signal. Example of a feed back signal is 4 - 20 mA signal from temperature transmitter, measuring a liquid temperature to PLC as input.
What do robot sensors do?
Robot sensors detect different things and send different amounts of electricity to the Robot's controller board to tell their findings. Then the controller board uses these different amounts of electricity to interact with its surroundings. Example: Lets say you have a robot that is made to follow light. Lets say your robot has 3 light sensors. One in the front of your robot one on the right and one on the left side. The sensors will detect how much light is on the front, right, and left sides and send this data to the controller board. Then the controller board uses this data to tell the robot with direction to go.
In computing what does APIC stand for?
In computing, the term APIC stands for Advanced Programmable Interrupt Controller. It is a more advanced version of a programable interrupt controller, which uses interrupts onto CPU lines.
What is programmable interrupt controller 8259A?
The Intel 8259A Programmable Interrupt Controller handles up to eight vectored priority interrupts for the CPU. It is cascadable for up to 64 vectored priority interrupts without additional circuitry. It is packaged in a 28-pin DIP, uses NMOS technology and requires a single a 5V supply. Circuitry is static, requiring no clock input.
What is ladder programming?
Ladder programming is used in Programmable Logic Controllers (PLC's) and is designed to be easily understood by engineers who are used to relay systems. It uses symbols for relay coils, timers and contacts. The advanced capabilities of the PLC e.g maths and logic functions are not used.
The diamond logic builder electrical system gauge cluster uses what to control the gauges?
There is a electrical system controller (esc) that's where the cluster gets its info from for example battery voltage
What are computer tubes used for?
Computer tubes, also known as vacuum tube computers are programmable computers that uses vacuum tube logic circuitry. They were used to solve computational problems much like modern day computers.
What are the two types of digital logic?
AOI logic, which uses AND, OR,and INVERTER(NOT) gates NAND/NOR Logic, this uses only NAND or NOR gates respectively.
What are the uses of not logic gates?
A NOT logic gate flips the logic signal from 1 to 0 or 0 to 1 :)

What does PLC mean in electrical?
PLC stands for Programmable Logic Controller. Basically its like a small computer that uses simple logic to execute automated processes, like in a factory. Lets say there is a factory that test balls for color. The desired color is Red and any other color is discarded. With the help of senors, the PLC will determine if the Ball is of Acceptable color and either trigger a sequence that transfers the ball to a different location, or kicks the balls of different colors out from the Passable balls. There are many types of PLC's. Some examples are SLICK 500 and Allen-Bradley. How ever this is only a small example of what PLC's are capable of doing.
