Spade-Terminal Relays
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.

Thin Spade-Terminal Relays
with Screw
Terminals
Spring-Clamp
Terminals
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.

DIN-Rail Mount Interface Relays
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.

DIN-Rail Mount Solid State Relays
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.
Relays with an integrated fan are best for applications that generate more heat. The fan automatically turns on to provide additional cooling. When the temperature exceeds 176° F, an alarm sends a signal to an external device, such as a controller or indicating light.

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

Screw Terminal Relays
Use the screw terminals to hardwire these relays. The built-in enclosure protects contacts from dust and dirt. These relays accept voltage drops up to 50% of the rated voltage without switching. They’re often used with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.
