PC817 Optocoupler 4 Channel Isolation Board Voltage Converter Adapter 3.3V to 5V Module 3.6-30V Driver Photoelectric Isolated

When encountering the need for isolation control and voltage conversion in actual work, this module will be used.

It can realize 3.3V or 5V control 3.6---24V voltage level interface. After the control terminal is turned on, the controlled terminal will also be turned on.

The photoelectric isolation has strong anti-interference ability. Later, it can drive high-power transistors, MOS tubes and other occasions that require high-voltage drive, and can also directly drive low-power 24V relays to work.

If it is a pulse signal, please note that the limit of 817 is below 4KHZ, please do not use this module for control signals greater than 4KHZ, it will not work properly.

Module parameters:

1. Signal voltage at the drive end: 3.6-24V

2. Output voltage range: 3.6-30V (The output current depends on the specific situation but the maximum is not 10MA. The total power is inversely proportional to a certain voltage and current)

3. The jumper cap can realize whether the output terminal is high-potential output or pull-down output.

4. The 2 or 4 channels on the board are independent, which can realize simultaneous control of different voltages, etc.
