Features 【Flexible Output Options】The isolation board comes with a jumper hat that allows users to choose between high flat output or pull-down output according to their specific needs. This feature offers greater flexibility and versatility in terms of the use of the board. 【Multiple Channels for Simultaneous Control】The 8 channels of 817 on the board are independent from each other, which allows users to control different voltages or other parameters simultaneously. This feature makes the card the ideal choice for complex applications that require multiple control channels. 【Control Interface Voltage Compatibility】The module is compatible with 3.3V or 5V control interface with voltage level of 3.6-24V. it will also turn on the controlled terminal, making it easier to use in a variety of applications. 【Versatile Driving Ability】The optical isolation of the board provides strong resistance to interference, allowing it to drive high-power transistors, MOS tubes and other high-voltage devices. It can also drive low power 24V relays directly, making it an ideal solution for a wide range of driving needs. 【High-quality PCB】The optocoupler isolation board is made of high-quality PCB materials which features reliability, miniaturization, good maintenance and interchangeability. This ensures consistent, long-lasting performance and makes it easy to integrate the board into your designs. Specifications: Item Type: Optocoupler Isolation Board Material: PCB Driver signal voltage: 3.6-24V Output voltage range: 3.6-30V (the output current depends on the specific situation, but the maximum power does 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 lower than 4KHZ, do not use this module for control signals higher than 4KHZ, it will not work properly.
