PC817 4 CH Optocoupler Isolation Module

Description:-

PC817 4 CH Optocoupler Isolation Module

This is a PC817 4-Channel Optocoupler Isolation Board. It features four independent 817 optocouplers, allowing for different voltage control simultaneously. By using the 4-way 817 optocoupler, you can achieve signal and control signal isolation. You can directly connect it to a microcontroller or other devices’ I/O ports for voltage isolation control. Additionally, you can use an external transistor or MOS tube on the control side to achieve small voltage control, or interface with devices operating at different voltage levels.

Applications:

I/O Isolation for MCUs (Micro Controller Units)

Noise Suppression in Switching Circuits

Signal Transmission Between Circuits of Different Potentials and Impedances

Features:

Driving Port Signal Voltage: 3.6-24V

Output Port Voltage Port: 3.6-30V

Output Can Be Switched From Pull-Up or Pull-Down With Jumpers.
