Features 1. High level or pull-down output: The 3.6-30V optocoupler isolation board has a jumper cap that allows you to easily switch between high-level output and pull-down output. You can choose the output terminal configuration that best suits your needs. 2. 8 independent channels to control different voltages: This AC optocoupler module has 8 independent channels, allowing you to control different voltages at the same time. It provides flexibility and convenience for a variety of applications. 3. Interface to open controlled terminals: The 8CH 817 optocoupler isolation board is designed to be compatible with 3.6-24v voltage levels, allowing you to open controlled terminals through a 3.3v or 5v control interface. This ensures seamless integration with your electrical equipment. 4. Drive various occasions: Due to the use of photoelectric isolation technology, this 8-channel driver photoelectric isolation module can drive high-power transistors, MOS tubes and other devices that require high-voltage driving. In addition, it can directly drive low-power 24v relays, making it adaptable to different application scenarios. 5. Excellent PCB quality: Driver Photoelectric Isolated Module is made of high-quality PCB materials to ensure reliability, miniaturization and good maintainability. Its interchangeability further enhances the item's usability and longevity. Specification: Item Type: Optocoupler Isolation Board Material: PCB Driver Signal Voltage: 3.6-24V Output Voltage Range: 3.6-30V (output current depends on the specific situation, but the maximum power is not exceed 10MA, the total power is constant, the voltage and current are inversely proportional) Package List:1 x Optocoupler Isolation Board Note: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, which will not work properly.
