A 4-channel relay module featuring 4x G3MB-202P solid state relays. This module 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. A resistive type fuse is provided on the module to help protect excessive current draw.
