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 2 x 3 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.

Features:

  • Comes as a kit providing lower cost
  • 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
