Product Description Single Relay Board Overview: 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 Single Relay Board Details: 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) Dimensions: Approximately 33.8 x 26.6 x 17.6 mm* Operating temp range: -13 to 158 °F (-25 to 70 °C) *Style and dimensions may vary slightly
