The Single Relay Board can be used to turn lights, fans and other devices on/off while keeping them isolated from your microcontroller. The Single Relay Board allows you to control high-power devices (up to 10 A) via the on-board relay. Control of the relay is provided via a 1 x 3 header – friendly to servo cables and convenient to connect to many development boards.
Key Features:
- Control high-power devices up to 10 A with a simple high/low signal
- Provides isolation between the microcontroller and device being controlled
- Screw terminals for relay connections
- 3-pin servo-style header for power/signal interface
- LED indicator provides visual feedback
Single Relay Board Application Ideas:
- 120 VAC brushless fan/lighting control
- 12 VDC automotive applications
- Voltage requirements: 5 VDC (Relay Power), 3.3-5 VDC (Input Signal)
- Current requirements: ~85 mA (Relay Power)
- Communication: Logic High/Low (3.3–5 VDC)
