Parallax Single Relay Board

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.

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)
