Description: 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... Less
