Solid State Relay, 40A, SSR-40DA – Sparkfun COM-13015
This solid-state relay (SSR) allows you to control high-current AC loads from a 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 are no moving contacts, solid-state relays can be switched much faster and for much longer periods without wearing out.
This particular flavour of SSR-40 can switch current loads of up to 40A with a 3-32V DC input and a zero cross trigger control method.
Each one of these solid state relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals.
