5V 2-Channel Solid State Relay Module - G3MB-202P SSR

A two-channel relay module featuring 2x Omron G3MB-202P solid state relays. This 5V 2-Channel SSR Solid State Relay Module 240V 2A Output with Resistive Fuse is capable of switching AC voltages between 100 and 240V at up to a 2A current. The module can be controlled from a 5V digital source such as an Arduino microcontroller.

This is a 2 Channel SSR relay module, each relay channel has 3 separate terminals, 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.
