SparkFun Solid State Relay - 40A (3-32V DC Input) General Mounting Hardware an inner diameter of 0A solid state relay (SSR) allows you to control high curent AC loads from lower voltage DC control circuitry. Solid state relays 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
