PC817 4 Channel Optocoupler Isolation Module

 

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

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

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.

If it's a pulsed signal, the 817 limit is 4KHZ or more. Please note that it is low. If the control signal is more than 4KHZ, please do not use this module, it will not work correctly.

Drive 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 constant, the voltage and current are reverse is proportional)

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

4 channels 817 are independent, allowing different voltages, etc. It can provide simultaneous control.

Dimensions: 48mm x 38mm
