Isolate input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal. These relays interface between your controller and components—they receive a signal from the controller to switch power on or off to the components. All have an LED indicator that shows you if your switch is actuated, so you know it’s connected and wired correctly. Use them to communicate signals to devices like motors or sensors. Mount them on 35 mm DIN rail (also known as DIN 3 rail).

Relays with spring-clamp terminals connect and disconnect to wires without needing to turn screws. Because there is no screw, these connections have less risk of loosening over time than screw terminals, even when there is vibration.

Relays with a fuse holder slot give you the option for additional overload protection. If the current exceeds the fuse’s rating, the fuse will blow and break the circuit. This prevents the relay from overheating, breaking, or causing a fire. The fuse holder is sold separately. You can use these relays without the fuse holder as a standard interface relay.
