Focus on these four details of the signal isolator

In addition to the function of the signal isolator, we also need to pay attention to these four details. With the small edition of Taihua, take a look at the four details of the signal isolator.

1. Power supply voltage

For such products as signal converters, we generally choose the power supply working voltage is 20~35VDC, so that we can use the power transformer in the control box to supply power and be stable. In addition, the signal isolator uses screws to tighten the connection to ensure the reliability of the power supply connection.

2, the internal temperature

A key effect of the signal isolator is to continuously optimize the software electromagnetic interference problem, in order to ensure the long-term smooth operation, so the signal isolator can be long-term reliable work is also necessary to consider, we will generally choose the use of load allocation, power consumption, ultra-low temperature rise technology products.

3. Self-protection ability

In addition to the signal isolator to suppress the electromagnetic interference in the data signal loop, its own anti-interference is also necessary to consider, the idea of the isolator itself in the electromagnetic interference can not all work normally, how to give the loop to show excellent impact suppression maintenance? So you can see inside the isolator, whether there are surge, electrostatic induction, transmission and other EMC maintenance components in the port number.

4. Warranty period

The warranty period is the quality assurance of the product, but also the service ability of the manufacturer to reflect, generally dare to publicize and plan a long shelf life manufacturers, all have key technologies and colorful on-the-spot work experience, in the product design scheme, testing, production and manufacturing, pre-sales service, after-sales service and other levels of overall strength, we can give priority to take into account the products of this manufacturer.
