Control two high-power devices, up to 8A each, using this Dual Relay Board Kit by Parallax. Once properly assembled, this relay board can be used to turn lights, fans and motors on or 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.
