PLC Definition(Programmable Logic Controller or ProgramÂmable Controller): PLC Definition - Programmable Logic Controller (PLC) or commonly simply called a ProgramÂmable Controller, is a solid state, digital, industrial computer. It is a device that was invented…
PLC Components: A PLC is a solid state device designed to perform logic functions previously accomplished by electro-magnetic relays. Basically, the PLC Components is an assembly of solid state digital logic decisions which provides outputs.…
PLC Basic Process: A PLC Basic Process is basically made up of the following sections, each of which has a unique function to perform in its operation. The sections are: Sensing inputs or controlling hardware…
PLC Applications: The PLC Applications takes a certain amount of time to react to changes. The total response time of the PLC is a fact that has to be considered while selecting a PLC for some…
Platinum Thin Film RTD Sensors: Platinum Thin Film RTD Sensors are manufactured by a very thin layer of platinum in suitable pattern to achieve smaller dimension and higher resistance, on a ceramic base. The deposition…
Platinum Resistance Thermometer: Platinum Resistance Thermometer - The resistance of a conductor changes when its temperature is changed. This property is used for measurement of temperature. The Resistance Thermometer uses the change in electrical resistance…
Planar Triode Construction: Planar Triode Construction - A short transit time is essential if grid loss and noise are to be minimized, as is the reduction of internal capacitances and inductances. Also, since coaxial resonant…
Plain Rheostatic Starting of Traction Motors (Notching): As already mentioned in this plain rheostatic starting method the voltage across the motor is gradually increased from zero to full (normal) voltage and the current is kept…
Pin Photodiode - Definition, Working and Applications: The PIN photodiode is one of the most common photodetectors, since the depletion-region thickness (intrinsic layer) can be tailored to optimize the quantum efficiency and the frequency response.…
Pin Diode Construction: The Pin Diode Construction consists of a narrow layer of p-type semiconductor separated from an equally narrow layer of n-type material by a somewhat thicker region of intrinsic material. The intrinsic layer…
