Solid State Relays

About Solid State Relays

Solid state relays (SSRs) switch AC or DC loads using a semiconductor output with no moving contacts, delivering long life and silent operation compared to electromechanical relays. This category covers panel-mount, DIN-rail, PCB, and socket-mount SSRs in common ratings from 1 A to 100 A+, with zero-crossing or random-fire turn-on and DC, AC, or analog control inputs.
