Treedix Opto-Isolator Breakout Board with Two Photodiodes Built-in Comes with 2 Channel Coupler for Blocking Circuit
  • The board electrically isolates the controller from the high-power system by using an opto-isolator IC. The opto-isolator breakout IC has built-in two LEDs and two photodiodes, allowing the low-voltage side to control the high-voltage side.
  • This is specially designed for optical isolation, which helps to connect digital systems to high-voltage or noisy systems.Good isolation performance, complete electrical isolation between input and output.
  • The breakout board uses ILD213T opto-isolator and discrete transistors to calibrate the logic, with two channels. It is very suitable for use in noisy circuits where signal lines need electrical isolation.
  • Using this board can allow the microcontroller to control the servo system or other motors. These motors use a higher voltage than the TTL logic on the micro (3.3V or 5V), and may affect our system when the motor is turned on and off. Cause electromagnetic interference.
  • Easy to connect logic circuits, fast response speed, high transmission efficiency: this optoisolator is configured for data rates up to 9600bps. Compatible with dual wave, vapor phase and IR reflow soldering
