AC Fundamentals: Let us discuss in brief, the AC Fundamentals necessary to analyse the networks consisting of various alternating current and voltage sources, resistances and inductive, capacitive reactances. An alternating…
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…
PLC Hardware: PLC hardware falls into the following physical configuration: Fixed Input/ Output (I/O) and Modular I/O. 1.Fixed 1/0 PLCs A fixed PLC Hardware consists of a fixed, or built-in,…
AC Input: The, ac input modules that are commonly available work with 24, 48, 110 and 220 V. It is important to use the one that fits the needs based…
Digital Process Control: A digital process control functionally needs to operate in much the same way as a conventional analog controller. That is, it must provide facilities to raise or…
Standing Wave Ratio Measurements: Standing wave are created along the length of a transmission line due to the mismatch between the characteristic impedance Z0 and the terminating impedance of the…
Measurement of Power Transmission Lines: When power is applied to Measurement of Power Transmission Lines, the source to load impedance must be matched in its characteristics impedance (Z0). The impedance…
Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a short ultra thin wire…
