Feature:

• 【Voltage range】：Drive terminal signal voltage: 3.6-24V. Output terminal voltage range: 3.6-30V (output current depends on the specific situation, but the maximum does not exceed 10MA, the total power is constant, and the voltage is inversely proportional to the current)

• 【Anti-interference ability and drive】：The module's photoelectric isolation has strong anti-interference ability. It can drive high-power transistors, MOS tubes and other applications that require high-voltage drive, and can directly drive low-power 24V relays.

• 【Application range】：The module can be used as long as isolation control and voltage conversion are required, and the application range is wide.

• 【Regarding pulse signal】：If it is a pulse signal, please note that the limit of 817 is 4KHZ or less. If the control signal is greater than 4KHZ, please do not use this module, otherwise it will not work normally.

• 【Features】：Using 817 optocoupler, you can directly use the IO port of a microcontroller or other device to achieve voltage isolation control, and can achieve low voltage control. The control terminal can be connected to an external transistor MOS tube or device interface with different voltage levels

Product description:The product has strong photoelectric isolation and anti-interference ability, and can drive high-power transistors, MOS tubes and other occasions that require high-voltage drive, and can also directly drive low-power 24V relays.
