PC817 8 Channel Optocoupler Isolation Module

This module is used when isolation control and voltage conversion are required.

It can realize 3.3V or 5V to control the 3.6-30V voltage interface. After the control terminal is opened, the controlled terminal will also be opened.

Photoelectric isolation has strong anti-interference ability. It can drive high-power triodes, MOS tubes and other applications requiring high voltage driving, and can also directly drive low-power 24V relays.

Please note that if it is a pulsed signal, the limit of 817 is 4KHZ or less. If the control signal is more than 4KHZ, please do not use this module, it will not work properly.

Driver 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 fixed, the voltage and current are inversely proportional)

Whether the output is a high potential output or a low potential can be realized with a jumper.

8 channels 817 are independent, can achieve simultaneous control of different voltages, etc.

Dimensions: 84mm x 38mm
