S-073N 3BHB009884R0021 A/D Conversion Element

The RTU unit of the S-073N 3BHB009884R0021 uses a transmitter to convert AC to DC before acquiring analog quantities, and then uses an RTUA/D converter element to represent the DC quantities as digital quantities. The device is based on analog circuitry, supplemented by a small amount of digital circuitry. It is characterized by the need for converters, without advanced digital processing unit (CPU, etc.), difficult to reflect the instantaneous changes in the analog quantity, harmonic analysis can not be carried out, the realization of the total addition of electrical energy is more complex and difficult.

The RTU device of S-073N 3BHB009884R0021 directly uses A/D conversion components to collect and calculate the AC power quantity without the need of conversion devices such as transmitters, but it needs a fast digital processing unit to cooperate in order to analyze and synthesize the collected data. It can not only reflect the instantaneous changes in the amount of electricity, but also can carry out harmonic analysis, calculate the frequency, and simply realize the total addition of electric energy function. They mostly use microcomputers (such as 8 X86, etc.) with a number of microcontrollers (such as 8051, 8098, etc.), and with a large number of A/D conversion circuits to achieve the collection of switching and analog quantities.

S-073N 3BHB009884R0021 With the full development and application of digital technology, the AC sampling scheme is a reasonable choice for distribution network automation. It is based on digital circuits, supplemented by a small number of analog circuits, powerful, easy to expand, the reliability of the DC sampling program has a greater increase in comprehensive low cost.
