4 Channel 817 Optocoupler Isolation Module

Its PC817 4 Channel Optocoupler Isolation Module‚ As we know that the optocoupler is basically used to isolates the two different circuits an Optocoupler Contains an IR LED and a photodiode when we give electrical signal to the optocoupler then its internally connected IR LED glows and the photo detector or transistor detect the signal and absorb the light and convert in to the electrical signal and send it to the another circuit here an optocoupler is working as a switch. Using a 4-way 817 optocoupler‚ you can directly use the microcontroller or other device’s IO port to achieve voltage isolation control‚ achieving a small voltage control‚ the control side can be an external transistor MOS tube or different voltage levels of the device interface.

Features:

• Its used to provide isolation using 4 way optocoupler
• Its Driving Port Signal Voltage is 3.6-24V
• Its Output Port Voltage Port is 3.6-30V
• Output Can Be Switched From Pull-Up or Pull-Down With Jumpers.
