Advantages and disadvantages of optocoupler relays

advantage
1. It has high insulation performance and can achieve high isolation between input and output circuits, improving the safety and stability of the system.
2. The switching speed is relatively fast, and the photoelectric coupling element has the characteristic of fast response, which can adapt to high-speed requirements.
3. Small size, light volume, and small space occupation make it advantageous in compact and high-density component layout scenarios
disadvantage
1. The output current and voltage capabilities are relatively low, and due to the limitations of optoelectronic coupling elements, they are only suitable for low-power and low-voltage applications.
2. The price is relatively high, and the manufacturing cost of optoelectronic coupling components is high
