Dual Relay Board Kit, 27114
Special Price £14.40 £12.00 Regular Price £28.55
Once assembled, the Dual Relay Board Kit allows you to control two high-power devices up to 8A 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 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
