PC817 4 Channel Optocoupler Module

Overview: The PC817 4 Channel Optocoupler Module is essential for applications requiring isolation control and voltage conversion. This versatile module allows seamless control of voltage levels from 3.3V or 5V to 3.6Vā€“24V. Ideal for both hobbyists and professionals, it provides reliable photoelectric isolation with strong anti-interference capabilities.

Key Features:

  • Voltage Control: Easily manage 3.3V or 5V control interfaces with output voltage levels between 3.6V and 24V.
  • High Voltage Driving: Suitable for driving high voltage components like power transistors and MOSFETs, as well as directly controlling low-power 24V relays.
  • Pulse Signal Limitation: Designed for pulse signals with a frequency below 4kHz. For signals above this frequency, this module is not recommended.
  • Flexible Output: Utilize the jumper cap to select between high potential or low potential output, tailored to your specific needs.
  • Independent Channels: Each of the four PC817 optocouplers on the board operates independently, allowing simultaneous control of different voltage levels.


  • Drive Terminal Signal Voltage: 3.6V – 24V
  • Output Voltage Range: 3.6V – 30V (Output current varies; maximum is 10mA)
  • Board Dimensions:
    • Length: 48mm
    • Width: 38mm
    • Long Side Hole Distance: 42mm
    • Wide Side Hole Distance: 32mm

Package Includes:

  • 1 x PC817 4 Channel Optocoupler Module

Applications: Perfect for applications requiring robust isolation and voltage conversion, such as:

  • Industrial automation systems
  • Microcontroller interfacing
  • Signal isolation in noisy environments
  • Driving high voltage components safely

Why Choose the PC817 Module? The PC817 4 Channel Optocoupler Module is a reliable and efficient solution for isolating and converting voltage levels in your electronic projects. Its strong anti-interference capabilities and versatile voltage control make it an indispensable component for ensuring the stability and performance of your circuits.

Note: For optimal performance, ensure that the pulse signal does not exceed 4kHz. For higher frequency signals, consider alternative modules designed to handle such requirements.
