Isolation amplifiers are used to protect data acquisition devices from potentially damaging voltages that occur with remote sensors. These amplifiers are also used to amplify low-level signals in multichannel applications. They can also eliminate measurement errors caused by ground loops. Since no additional isolation power is required, isolation amplifiers with internal transformers can reduce circuit costs.About:The isolation amplifier is a special measurement amplifier circuit that has no direct circuit coupling between the input, output and power supply circuits, that is, there is no common ground terminal for the signal during transmission. A device with ohmic isolation between the input circuit and the amplifier output.Is in the automatic control system for voltage and current, AC, 4-20mA, 0-5V, mV mV, PWM pulse, Hz frequency, Pt100 thermal resistance, sine wave, square wave, potentiometer, speed and other signals for transmission, conversion, isolation, amplification, remote transmission of the integrated circuit, can be used with a variety of industrial sensors, Meet the needs of local monitoring remote data collection.
