This module will be used when isolation control and voltage conversion are required in actual work.
It can realize the interface of 3.3V or 5V controlling 3.6---24V voltage level. After the control end is turned on, the controlled end will also be turned on.
The photoelectric isolation has strong anti-interference ability. It can drive high-power triodes, MOS tubes and other occasions that require high voltage drive, and can also directly drive low-power 24V relays.
If it is a pulse signal, please note that the limit of 817 is below 4KHZ. Please do not use this module for control signals greater than 4KHZ, as it will not work properly.
