Key Features of 2-Ch 5V relay Board with optocoupler
- Optocoupler Isolation: Electrically isolates the microcontroller from high-voltage relay circuits, preventing noise, voltage spikes, and ground loops from damaging your logic board
- 2 Independent Channels: Control two separate appliances or loads simultaneously with individual relay outputs
- SPDT Relay Contacts: Each channel provides Normally Open (NO), Normally Closed (NC), and Common (COM) terminals for maximum wiring flexibility
- Low-Level Trigger: Active-LOW input means the relay energizes when the input pin is pulled to GND - compatible with most microcontroller GPIO outputs
- High Current Handling: Each relay can switch loads up to 10A at 250V AC or 30V DC, suitable for lights, fans, motors, heaters, and solenoids
- LED Status Indicators: Individual red LEDs show relay activation status at a glance; green LED confirms board power
- Screw Terminal Connections: Secure, tool-tightened screw terminals for reliable high-voltage load wiring
- Compact & Mountable: Small PCB footprint with four M3 mounting holes for clean installation in enclosures and project boxes
- Wide Voltage Logic Compatibility: Works with both 3.3V and 5V logic levels, making it compatible with Arduino, ESP32, Raspberry Pi, and more
- Durable Relay Construction: Rated for 100,000 mechanical cycles, ensuring long-term reliability in repeated switching applications
- Safe Isolation Design: Optocoupler-based isolation protects your expensive microcontroller from relay-side electrical noise and surges
- Plug-and-Play Simplicity: Standard pin header interface connects directly to Arduino and other boards - no additional driver circuitry required
- Versatile Load Switching: Handle everything from low-voltage DC devices to mains-powered AC appliances with a single module
