This is Solid State Relay 25A SSR-25DA with Trigger voltage  3-32 VDC Load switching voltage 24-380 VAC, it can switch current loads of up to 25A 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.

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 are no moving contacts, solid-state relays can be switched much faster and for much longer periods without wearing out.
