Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. An LED indicator lights up when these relays are connected, so you can quickly confirm that they’re wired correctly. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.

Relays with an integrated heat sink disperse heat to increase the relay’s current rating.

With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission. The relay’s LED indicator shines when it’s powered on, so you know at a glance which relays are wired correctly and what the switching position is. These relays are often used for switching small motors and sensors. Rated IP20, they prevent fingers and other objects from touching live circuits.

Mount them on 35 mm DIN rail (also known as DIN 3 rail) with the included socket. Relays disconnect from the socket for easy replacement.
