Fit these relays where standard spade-terminal relays are too big. You can connect them three ways. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals. An LED indicator shows you the status of the relay, so you know it’s connected and wired correctly.

Relays that control 2 or more circuits have a lockable test button, so you can test their function. When you press the button, the relay switches contacts. Use this button when checking a relay for proper function before installing it, or when investigating issues with wired relays.

Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. You can also mount them to a flat surface using screws.

Save space in your control cabinet. These narrow relays are often used for low-current switching applications, such as on small motors and pilot lights. They plug into a socket (sold separately) for quick installation.

Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail). Those with screw terminals connect and disconnect wire when you turn the screws. They can also mount to a flat surface. Those with spring-clamp terminals connect and disconnect to wires without needing to turn screws. Insert a screwdriver into the slot to release the spring clamp holding the wire in place.

Often used for high-speed switching at low-current levels, these solid state relays have no moving parts, so they switch faster, last longer, and are quieter than mechanical switches.

Heat sinks disperse heat to increase the relay’s current rating. Mount to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces.

Relay sockets with screw terminals can also mount to a flat surface.

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.

Relays with PLC output protection prevent voltage spikes created by the relay from damaging the output channel on your programmable logic controller (PLC).

With no moving parts, these solid state relays require less maintenance and last longer, switch faster, and are quieter than mechanical relays. They can handle high starting (inrush) currents. The blade terminals meet ISO 8092-1 dimensions, ensuring they are compatible with the electrical connections in road vehicles you need to maintain or repair. Also known as ISO relays or automotive relays.

An extended housing shields the terminals on these relays from weather. They're also rated IP54—when they're plugged into the relay socket, they're sealed to keep splashing water, like rain, from getting inside. They handle high starting (inrush) currents that often occur when turning on a vehicle. To prevent damage to sensitive equipment, these relays will partially suppress a momentary surge in voltage when the relay switches off. They’ll take a voltage spike of 300V to 500V and bring it down to 100V.

Relays for surface mounting have a tab for added security in high-vibration applications.
