Features Versatile Output Options: The jumper cap allows you to choose between high-level or pull-down output on the terminal, providing flexibility in your applications. Independent Channel Control: With 8 channels of the 817 optocoupler, you can simultaneously control different voltages or devices independently. Wide Voltage Compatibility: The module supports control interfaces of 3.3V or 5V for voltage levels ranging from 3.6V to 24V, ensuring compatibility with various systems. Powerful Drive Capability: The optocoupler isolation board is capable of driving high-power transistors, MOS tubes, and other high-voltage devices. It can also directly drive low-power 24V relays, making it suitable for various applications. Reliable PCB Design: The high-quality PCB materials used in this module ensure excellent reliability, miniaturization, easy maintenance, and interchangeability, guaranteeing a long-lasting performance. 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.
