5V 1 Channel H/L Level Trigger Optocoupler Relay Module For Arduino
Control high-power AC and DC loads from your Arduino or Raspberry Pi with this optocoupler-isolated relay module. The jumper-selectable high/low level trigger gives you flexibility, while optical isolation protects your microcontroller from electrical noise and back-EMF.
Features fail-safe design—if the control line is disconnected, the relay stays off. Status LEDs show power and relay state at a glance.
Key Features
- Optocoupler Isolated – Protects your microcontroller from relay noise
- Selectable Trigger Level – Jumper to choose high or low level activation
- Fail-Safe Design – Relay won't activate if control line breaks
- Status LEDs – Green for power, red for relay state
- Screw Terminals – Easy connection for loads
- Mounting Holes – Four 3.1mm holes for secure installation
