DIN-Rail Mount Solid State Interface Relays
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.
Relays with spring-clamp terminals connect and disconnect to wires without needing to turn screws. With no screws to shake loose with vibration, these terminals hold tight over time.
