PC817 2 channel optocoupler isolation board is independent, can control different voltage at then same time. 2-way 817 optocoupler driving port signal voltage:3.6-24V; Output voltage range: 3.6-30V(The output current depends on the specific situation but not over 10MA. When the total power is fixed, the voltage and current are inversely proportional). 2 way 817 optocoupler to achieve the control signal and the control signal isolation, you can directly use the microcontroller or other devices IO port to achieve voltage isolation control, you can achieve a small voltage control, the control side can be an external transistor MOS tube or different voltage levels Of the device interface. PC817 module jumper cap can be used to determine whether the output terminal is high potential output or low output. If it is a pulse signal, please note that the limit of 817 is below 3KHZ. If the control signal is greater than 3KHZ, please do not use this module, it will not work properly. PC817 Optocoupler Module can achieve an interface with a voltage level of 3.6-24V controlled by 3.3V or 5V. After the control terminal is connected, the controlled terminal will also be connected. Strong photoelectric isolation and anti-interference ability. Later, it can drive high-power transistors, MOS transistors, and other occasions that require high voltage driving, or directly drive low-power 24V relays to work. If it is a pulse signal, please note that the limit of 817 is below 4KHZ. For control signals greater than 4KHZ, please do not use this module as it will not work properly.
