PC817 4 CH Optocoupler Isolation Module
Description:
PC817 4-Channel Optocoupler Isolation Module is a versatile electronic component designed to provide electrical isolation between different parts of a circuit, specifically between low-voltage control and high-voltage or high-current systems. It uses PC817 optocouplers, which are known for their reliable isolation performance and are commonly employed in signal transmission applications. This module allows safe and efficient communication between circuits that have different voltage levels, preventing high voltage from damaging sensitive components in the low-voltage side.
Features:
1. 4 Independent Channels
2. Optocoupler Type - PC817
3. Electrical Isolation
4. Wide Voltage Range
5. High Isolation Resistance
6. Current Transfer Ratio (CTR)
7. LED and Phototransistor Integration
8. Compact and Easy to Integrate
9. High-Speed Signal Transmission
10. Protection Against Voltage Spikes
