Description
This 2-Channel Relay Module allows microcontrollers to safely and independently control two high-power electrical appliances at the same time. Equipped with high-current switching capacity and optocoupler isolation, it is a reliable choice for switching lights, motors, fans, and AC equipment.
Key Features:
- Dual Channel Control: Operates 2 independent relay channels to trigger two separate high-power circuits or devices simultaneously.
- High Switching Load: Controls load up to 250V AC / 10A and 30V DC / 10A on each channel.
- Optocoupler Isolation: Integrated optocouplers protect your sensitive low-voltage microcontroller from back-EMF, high-voltage spikes, and electrical noise.
- 2-State NO/NC Terminals: Each channel features a 3-pin heavy-duty screw terminal (Normally Open, Common, Normally Closed) for flexible wiring options.
- LED Status Lights: Equipped with individual trigger LEDs for each channel, providing instant visual feedback when a relay activates.
- Broad Microcontroller Compatibility: Works seamlessly with 5V logic inputs from Arduino, Raspberry Pi, ESP32, ESP8266, and PIC boards.
- Versatile Applications: Ideal for smart home automation, dual-load motor controls, automated lighting systems, and DIY robotics projects.
