PC817 2 Channel Converter Optocoupler Isolation Board 2 CH Opto Module

PC817 2 Channel Converter Optocoupler Isolation Board 2 CH Opto Module

This module is used in actual work when isolation control is required and voltage conversion is required.
It can realize 3.3V or 5V control 3.6---24V voltage level interface, after the control terminal is turned on, the controlled end will also be conducted.
Strong photoelectric isolation and anti-interference ability. The back can drive high-power transistors, MOS transistors 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, and please do not use this module for control signals greater than 4KHZ, it will not work properly.

Module parameters:
1. Signal voltage at the driving end: 3.6-24V
2. Output voltage range: 3.6-30V (output current depends on the specific situation but not 10MA, the total power must be inversely proportional to voltage and current)
3. Through the jumper cap, you can realize whether the output end is high potential output or pull low output.
4. The 2 channels 817 on the board are independent, which can realize the simultaneous control of different voltages
