It is common in the industry to measure various
DC current transducer, an automation product, is popularly used in automation control systems for various industrial signal transmission, conversion, isolation, transmission, and calculation, as automation technology is more and more popular in the industrial field. It can cooperate with various industrial sensors to retrieve parameter signals, isolate transmission and transmission, and meet your needs for local monitoring and remote data collection. But you may don’t know much about DC current transducers. This article will introduce you to what is a DC current transducer.
The DC current transducer is a device that converts the measured electrical parameters into DC current and DC voltage and isolates and outputs analog or digital signals. The measured signal can be converted into a voltage, which can be directly converted into a voltage with an excellent linear relationship with the measured signal and completely isolated by the HCNR200/201 linear optocoupler, and then output through constant voltage (current). The dc current transducer complies with national standard GB/T13850-1998. It is used to measure the voltage or current signal with serious waveform distortion in the grid, and it can also measure non-sinusoidal waveforms such as square waves and triangular waves.
DC current transducers are frequently used in data acquisition, signal transmission conversion, plc, DCS, and other industrial measurement and control systems in the fields of machinery, electrical, telecommunications, electric power, petroleum, chemical industry, steel, sewage treatment, and building construction, among others, to enhance and supplement system simulation. I/O plug-in functionality improves field environment dependability and system adaptability.
