5V 2 channel Low level solid state relay module 240V 2A output with resistive fuse
This is a 5V 2 channel low level solid state relay module. This module is capable of switching AC voltages between 100 and 240V at up to a 2A current. This is a 2 Channel relay module, each relay channel has 3 separate terminals, NO (Normal Open), COM (Common), NC (Normal Closed). A Solid State Relay is similar to a mechanic relay, but it is a low-level trigger relay. So the relay will turn on at LOW level input. And hence it can be control through a digital signal. This relay module generates no noise and has a much longer lifespan.
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.
