About Solid State Relays
Serving the same purpose as the electromechanical relay—without the moving parts—the solid state relay provides a self-contained relay that switches on or off when external voltage is applied across its control terminals. Depending on your needs, you can find solid state relay circuits, relay switches, opto and dpdt relays, AC solid state relays and more. Solid state relays isolate electricity between input and output contacts, providing maximum resistance when open and low resistance when closed. AC and DC currents can be switched using a solid state relay. You can also shop for relay accessories and time delay relays.
