Key Features
- Dual Independent Channels: Control two separate appliances, motors, lights, or loads simultaneously from a single module.
- Optocoupler Isolation: Built-in optical isolation between the microcontroller signal side and the relay coil side prevents voltage spikes and back-EMF from damaging your development board.
- High-Current Switching: Each relay handles up to 10A @ 250V AC or 10A @ 30V DC - powerful enough for household appliances, solenoid valves, water pumps, and more.
- SPDT Relay Contacts: Each channel provides Normally Open (NO), Normally Closed (NC), and Common (COM) terminals, giving you full flexibility for both ON-switching and OFF-switching logic.
- Active Low Trigger: Relays activate when the input pin is pulled LOW, making it compatible with most microcontroller GPIO configurations.
- LED Status Indicators: Individual red LEDs on each channel provide instant visual confirmation of relay activation - invaluable during debugging and testing.
- Screw Terminals for Load Wiring: Secure, robust screw terminal blocks for connecting high-voltage AC/DC wires - no soldering needed on the output side.
- Standard Pin Header Input: Easy plug-in connection to breadboards or direct jumper wire hookup to any microcontroller.
- Compact & Mountable: Four M3 mounting holes allow secure installation inside enclosures, control panels, or project boxes.
- Wide MCU Compatibility: Works seamlessly with Arduino, ESP32, ESP8266, Raspberry Pi GPIO, STM32, PIC, and virtually any 5V-logic microcontroller.
