What measures the signal isolator takes to prevent interference

Due to the harm of the natural environment for the application of the signal isolator, its surroundings usually use a variety of machines and equipment that cause strong interference in the work of the signal isolator, such as DC welding machines, controllable machines, and automobile relay contacts, in order to make the signal isolator all normal applications, and the signal isolator must adopt certain anti-interference measures. So according to what measures can the signal isolator carry out anti-jamming? Taihua Xiaobian to tell you.

1, the use of hardware configuration route to suppress the harm of each machine equipment interference, can be transmitted to a interference control board according to the switching power supply input end of the signal isolator or add a very isolated transformer, which can achieve a very good anti-interference actual effect, the specific use of the signal isolator is often connected to the input end of a zinc oxide varistor, It can reasonably use the peak time resistor to reduce the operating voltage from the switching power supply, so as to reduce the effect of interference.

2, using the installation program to carry out anti-interference. When some mobile phone software is installed on the signal isolator, when regular interference occurs, the computer can be used to develop programs to achieve the purpose of the filter, so as to eliminate interference.

3, the use of hard and soft combination of anti-interference. This type of method combined with the above two methods can resist more types of interference, and the resistance is also greatly improved. It is also more anti-interference measures used at this stage.

It is the signal isolator common three anti-interference measures, in addition to these three, sometimes some areas will be based on the switching power supply sort of power supply system or modify a noise filter to help the signal isolator resist a variety of machine equipment interference, which can be selected according to the type of signal isolator.
