Using a low-current signal, these relays are often used to control small motors and heaters. These relays attach to quick-disconnect terminals.

Surface mount relays, also known as power relays, have a slot on the flange for mounting them to flat surfaces.

Relay-socket mount relays, also known as ice cube relays, offer three ways to connect. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals.

Relay-socket/surface mount relays can plug into a socket or mount to a flat surface.

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

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.

Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

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

The circular pin terminals plug into relay sockets for easy installation. Also known as ice cube relays.

Relays rated for horsepower (hp) are built to handle tough, repetitive-use applications.

Relays with a lockable test button allow you to test whether a relay is working without an electrical signal. They’re helpful for testing relays before you install them, or for checking that installed relays are working properly.

Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) or can be mounted 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).

These relays pair the transmission reliability of an interface relay with the fail-safe operation of a safety relay. Use them to communicate signals to devices like motors or sensors. They have interlocking contacts—also known as force-guided or mechanically linked contacts—so opposing contacts won't close at the same time. This minimizes the chance of arcing, so electricity won't jump across the contacts and interfere with your relay or system. They also have an interface that isolates input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal. Mount them on 35 mm DIN rail (also known as DIN 3 rail). The relays disconnect from the socket for quick replacement.

Relays with LED indicator light up when the relay is on, so you’ll know it’s wired correctly and can tell at a glance whether it’s on or off.
