Although the efficacy of the signal isolator is more, the characteristics are better, but the quality of the signal isolator manufactured on the sales market is also different, so we must understand some specifications to consider the quality of the signal isolator when selecting.

Specification 1. Refer to the isolation strength of the signal isolator. Isolation strength is also called isolation working capacity or compressive strength. We know that the signal isolator mainly has the effect of isolating the data signal, so the isolation strength of the basis can reflect the overall quality level of a signal isolator, when purchasing, we must recognize how much the isolation strength of the signal isolator you want to buy is, generally the larger the better, the isolation strength of the enterprise is amper@1.

Specification two, to see the accuracy of the signal isolator, the manufacturing industry often takes the accuracy as a scale to consider the quality of the signal isolator, the smaller the accuracy, the better the quality of the signal isolator.

Specification III. Temperature coefficient of signal isolators. The temperature coefficient is used to show the change in the accuracy of the signal isolator at different temperatures, because the natural environment in which the signal isolator is applied is usually different, so this index is also forced to look at this purchase.

Above is the purchase of signal isolator when the three key specifications, in addition to the signal isolator response speed, grounding resistance, and input resistance will also cause very great harm to the quality of the signal isolator, the purchase should also pay more attention to the main parameters of this level.
