【ADAPTER MODULE APPLICATION SCENARIO】: The 4-way Voltage Isolation Board is used when isolation control and voltage conversion are required in actual operation.
【VOLTAGE CONVERTER FUNCTION】: Optocoupler Isolated Board can realize 3.3V or 5V to control the 3.6-24V voltage level interface. After the control terminal is turned on, the controlled terminal will also be turned on.
【STRONG ANTI-INTERFERENCE ABILITY】: The 4 Channel Optocoupler Isolated Board has strong anti-interference ability and can drive high-power transistors, MOS tubes and other places that require high-voltage drive. The 4-way Voltage Isolation Board can also directly drive low-power 24V relays.
【NOTE FOR VOLTAGE CONVERTER】: If optocoupler is a pulse signal, please note that the 817 limit is below 4KHZ. If the control signal is greater than 4KHZ, please do not use this module, the 4-way Voltage Isolation Board will not work normally.
【EFFECTIVE VOLTAGE ISOLATION BOARD】: Optocoupler Isolated Board can realize whether the output is high-potential output or low-potential output through the jumper cap.
