Do you need an optocoupler?

If you're creating an electronic device that will be vulnerable to voltage surges, lightning strikes, power supply spikes, and other such events, you'll need a way to protect low-voltage devices. An Optocoupler, when used correctly, can effectively: Signals should be free of electrical noise.

What are optocouplers used for?

Optocouplers can be used as a switching device on their own or in conjunction with other electronic devices to provide isolation between low and high voltage circuits. These devices are commonly used for the following purposes: Within these applications, you’ll encounter various configurations. Some examples include: Opto Transistor DC Switch

Are optocouplers safe?

The optocoupler can play a very good safety role, even when external equipment fails, even when the input signal line is shorted, and will not damage the instrument.
