  • SparkFun Solid State Relay - 40A (3-32V DC Input)

    A solid state relay (SSR) allows you to control high-current 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're no moving contacts, solid-state relays can be switched much faster and for much longer periods without wearing out.

    This particular SSR 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 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.


    • Trigger Current: 7.5mA/12V
    • Control Voltage: 24-380V AC
    • Input Voltage: 3-32V DC
    • Zero Cross
