Overview

Once properly assembled, the Dual Relay Board Kit allows you to control two high-power devices up to 8 A each via the included Omron mechanical relays.  The Dual Relay Board can be used to turn lights, fans, and motors on/off while keeping them isolated from the microcontroller.  Independent control of each relay is provided via a 2x3 header, making it friendly with servo cables and providing a convenient connection to many development boards, such as the Board of Education, Propeller Board of Education, Professional Development Board and Propeller Professional Development Board. LEDs indicate relay status.

Key Features:

  • Control two high-power devices with one kit  
  • Provides isolation between microcontroller and device being controlled  
  • Easy screw terminals for relay contact and power connections  
  • 3-pin servo-style headers for easy connection using standard servo cables  
  • LED indicators provide status of each relay

Application Ideas:

  • 120 VAC brushless lighting/fan control
  • 12 VDC automotive applications
  • HVAC duct/damper control 

Details
