G3MB-202P

5V 1 CHANNEL SSR MODULE

This is a 1-channel solid state relay (SSR) for AC power that can be controlled directly via a microcontroller.

This device has a 2A resettable fuse to protect against overload conditions. Microcontroller inputs are isolated with an input transistor and opto-isolation that activates the switch on a LOW input signal with almost 0 current from your micro controller!

SSRs are great because they do not have inductive switching noise from a mechanical switch and do not wear out.

The important thing to remember is that due to the design of this switch, DC power is not recommended because it may not switch off without crossing 0 volts.
