Switchers & Dimmers By Shutao

• Onboard 4 channel 817 are independent: can achieve different voltage control at then same time
• 4-way 817 optocoupler driving port signal voltage:3.3-24V; 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)
• 4 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 achieve output port is high potential or pull down 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.
