G468-0001 is a signal isolator, is an important industrial control equipment, its main role is to achieve the isolation of the input signal and convert the output. This device adopts the principle of photoelectric isolation or magnetoelectric isolation to ensure the electrical isolation between the input, output and working power supply, and is especially suitable for use with equipment and meters that need to be electrically isolated.

Signal isolators have many advantages. First of all, the G468-0001 can effectively solve the problem of different ground reference points when the ground loop is connected to the equipment. Secondly, it can remove the infinite radio frequency and electromagnetic interference that the line may be subjected to during transmission, thereby improving the stability and accuracy of the signal. In addition, the signal isolator also has advanced digital technology, such as digital adjustment, zero and full degree potentiometer, automatic dynamic calibration of zero, automatic compensation of temperature drift, etc. The application of these technologies makes the stability and reliability of the product have been scientifically guaranteed.

According to different functions and application scenarios, signal isolators can be divided into active signal isolators and passive signal isolators. The active signal isolator can convert the analog voltage or current signal into a hybrid integrated circuit with matching accuracy and linearity. The passive signal isolator does not need an external power supply, and can obtain a little energy from the input signal to achieve signal isolation.

When selecting a signal isolator, the G468-0001 needs to consider several factors. First of all, it is necessary to ensure that the isolator can meet the needs of the input and output functions, and its input and output modes (such as voltage type, current type, loop supply type, etc.) should be adapted to the front and rear channel interface mode. In addition, precision, power consumption, noise, insulation strength, bus communication function and other parameters are also important factors to consider when selecting isolators. For example, accuracy determines the error size of the signal isolator during the conversion process, while power consumption and heat are closely related to the reliability of the product.

In short, G468-0001 plays a pivotal role in the industrial control system, and its correct use and selection are of great significance to ensure the stability and accuracy of signal transmission.
