HAPPY HOLIDAYS! WE WILL BE CLOSED FROM DEC 23 TO JAN 1.
2 Ch 5V 10A DC Relay Board
A relay is a switch which can be controlled through a digital signal. This is a 2 Channel DC relay module, each relay channel has 3 separate terminal, NO (Normal Open), COM (Common), NC (Normal Closed).
When the input logic voltage is applied to the coil, the NC will disconnect from the COM breaking the conductivity between the two. At the same time the NO will connect with the COM allowing conductivity between them. Depending on your wiring this will turn on or off the connected load.
