A solid state relay (SSR) is just what it sounds like; an IC that acts
like a mechanical relay. They allow you to control high-voltage AC
loads from lower voltage DC control circuitry. Solid state relays,
however, have several advantages over mechanical relays. One such
advantage is that they can be switched by a much lower voltage and at
a much lower current than most mechanical relays. Also, because
there's no moving contacts, solid state relays can be switched much
faster and for much longer periods without wearing out.
This kit has everything you need to make use of an SSR in your next
high-voltage project. After soldering together the through-hole kit,
simply attach your AC load and switch it on and off using your
microcontroller. This is a great kit for through hole soldering
practice and is really handy for controlling lights, water pumps, fans
or any other intermittent high-voltage device.
Note: These work with AC loads only. Great care, safety, and knowledge
should be used with high current and voltage.
