4-Channel 3.3V to 5V to 0.6V Optocoupler-Insulated Voltage Converter Adapter Board with Photoelectric Isolation for Relay Control

[Important Note on Pulse Signal Limitation] Please note that this module is designed for signals below 4 kHz. For pulse signals exceeding 4 kHz, the module will not function correctly. Ensure that your control signal frequency is within this limit to guarantee proper operation and avoid performance issues. [RELIABLE ISOLATION AND VOLTAGE CONVERSION] This 4-channel optocoupler isolated board is specifically designed for applications requiring isolation control and voltage conversion. It seamlessly converts 3.3V or 5V control signals to interface with voltage levels from 3.6V to 24V. When the control terminal is activated, the controlled terminal responds instantly, ensuring reliable operation in your projects. [STRONG ANTI-INTERFERENCE WITH PHOTOELECTRIC ISOLATION] Featuring robust photoelectric isolation technology, this module offers excellent anti-interference capabilities. It can drive high-power components such as Power triodes and MOS tubes for high-voltage applications, or direct control of low-power 24V relays. This makes it a versatile solution for various electronic control systems.
[FLEXIBLE OUTPUT CONFIGURATION WITH JUMP CAP] The module includes a jumper cap that allows you to easily choose between a high-potential or low-potential output. This flexibility allows you to tailor the output behavior to the specific requirements of your circuit, simplifying integration and improving usability in different projects.
[INDEPENDENT CHANNELS FOR MULTI-VOLTAGE CONTROL] Each of the four channels and the board's 817 optocoupler operate independently. This design allows you to simultaneously control different voltages and signals without interference, making it ideal for complex systems where multiple isolated control paths are required.
