4 CH OPTO RELAY MOD (5V)

4 CH Opto Relay Module (5V) ek 4-channel relay switching module hai jo Arduino, ESP8266, ESP32, Raspberry Pi jaise controllers se 4 different AC/DC devices ko ON/OFF control karne ke liye use hota hai.
Isme opto-isolation (Optocoupler) hota hai jo controller ko high voltage noise/spikes se protect karta hai.
