2Pcs PC817 8 Channel Optocoupler Isolation Board 3.6-30V Driver Photoelectric Isolated Module Voltage Converter Adapter Module

Color: 8 Channel

PC817 8 Channel Optocoupler Isolation Board Module Color: 8 Channel This 8-channel optocoupler isolation board is suitable for applications that require isolated control and voltage conversion. The input signal voltage for the eight 817 optocoupler drive terminals ranges from 3.6V to 24V. The output terminal voltage range is 3.6V to 30V. The output current depends on the specific application, with a maximum not exceeding 10mA. Total power remains constant, with voltage and current being inversely proportional. It allows control of a 3.6-30V voltage interface using 3.3V or 5V signals. When the control terminal is activated, the controlled terminal is also activated. Photoelectric isolation provides strong anti-interference capability. This board can drive high-power transistors, MOSFETs, and other applications requiring high-voltage drive, and can also directly drive low-power 24V relays. For pulse signals, please note the 817 optocoupler has a frequency limit of 4kHz or less. If the control signal frequency exceeds 4kHz, this module will not function correctly.
