2 Channel 5V Relay Module With Optocoupler Protection

2 Channel 5V Relay Module with Optocoupler – High Current Relay Driver Module for Arduino, ESP32, Raspberry Pi The 2 Channel 5V Relay Module with Optocoupler is a reliable and safe solution for controlling high voltage AC or DC loads using low voltage microcontrollers like Arduino, ESP32, or Raspberry Pi. Featuring opto-isolation (optocoupler protection), this module ensures complete electrical isolation between the control circuit and the relay, protecting sensitive devices from voltage spikes and noise. Key Features: Dual Channel Control: Independently control two AC or DC loads using microcontroller outputs. Optocoupler Isolation: Ensures protection and electrical isolation between low-voltage control and high-voltage switching circuits. High Current Relays: Each relay supports up to 10A at 250V AC or 10A at 30V DC. Indicator LEDs: Onboard status LEDs show the relay state for each channel. Active Low Trigger: Relay is triggered when input signal is LOW (can be changed with jumper setting). Screw Terminals: Easy and secure connection for load wiring.
