This module is designed for isolating and converting voltages. It uses a 4-way 817 optocoupler to separate control signals and achieve voltage conversion. You can connect it to a microcontroller or other devices’ IO ports for isolated voltage control, supporting voltage ranges from 3.6V to 30V with either 3.3V or 5V control signals.
When you activate the control terminal, the corresponding controlled terminal also activates. You can choose between high or low output using a jumper cap. The four channels on the board with 817 optocouplers work independently, allowing you to control different voltages simultaneously.
This module offers strong interference resistance due to its photoelectric isolation feature. It can handle high-power transistors, MOS tubes, high-voltage applications, and even control low-power 24V relays directly.
