A voltage transmitter is a device that converts an AC voltage, a DC voltage, and a pulse voltage to be measured to output a DC voltage or a DC current in a linear ratio, and isolates an analog signal or a digital signal. 1. Voltage transformer: Turn high-voltage electrical signals into low-voltage signals and isolate them from each other. 2. Opto-isolator: Turn the voltage signal of the power system into a low-voltage signal and isolate them from each other. 3. Voltage/frequency transmitter: Turn the voltage signal into a frequency signal and isolate them from each other. 4. Turn the AC voltage signal into a DC signal and isolate them from each other. A voltage transmitter is a device that converts the measured AC voltage, DC voltage, and pulse voltage into a linear proportional output DC voltage or DC current and isolates the output analog or digital signal. Adopt universal sensor voltage and current signal, input voltage signal: 0~5V/0~10V/1~5V 3. Output current signal: 0~10mA, 0~20mA, 4~20mA 4. Output voltage signal: 0~5VDC, 0 ~10VDC, 1~5VDC. The voltage transmitter is divided into a DC voltage transmitter and an AC voltage transmitter. The AC voltage transmitter is an instrument that can convert the measured AC current (AC voltage) into a linear proportional output DC voltage or DC current. It is used in electrical equipment, automatic control and dispatching systems of electric power, post and telecommunications, petroleum, coal, metallurgy, railway, municipal and other departments. The AC voltage transmitter has a single-way, three-way combination structure. DC voltage transmitter is a kind of instrument that can convert the measured DC voltage into DC voltage or DC current in linear proportion. It is also widely used in power, remote monitoring, instrumentation, medical equipment, industrial automation, etc. The industry of measurement and control. 1.
