The G448-0002 is an isolation amplifier, a special measurement amplifier circuit that has no direct circuit coupling between the input, output and power circuits, that is, there is no common ground terminal for the signal during transmission. It is primarily used to protect data acquisition devices from potentially damaging voltages that occur with remote sensors, to amplify low-level signals in multi-channel applications, and to eliminate measurement errors caused by ground loops.

The main function of G448-0002 is to increase the signal and ensure the accuracy of the signal. It provides isolation from one part of the circuit to another, so power is not consumed, used, and wasted in the circuit. The isolation amplifier also breaks the ohmic continuity of the electrical signal between the input and output, providing isolated power to the input and output so that low-level signals can be amplified.

G448-0002 has a variety of isolation methods, the common are capacitive isolation, optocoupler isolation and magnetoelectric isolation (transformer). Among them, the capacitor isolation is realized by the isolation of the capacitor through the transmission characteristic. Optocoupler isolation is the use of photoelectric devices to convert optical signals into electrical signals to achieve isolation. Magnetoelectric isolation is the transmission of the signal from the primary to the secondary through the transformer, which plays the role of electrical isolation.

G448-0002 is widely used in automatic control system, 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, can be used with a variety of industrial sensors, Meet the needs of local monitoring remote data collection.

In short, G448-0002 is an important electronic measuring instrument, with high isolation voltage, high common-mode rejection ratio, low noise, low distortion and other advantages, widely used in industrial automation, instrumentation, medical equipment, communication and other fields.
