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.

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

Circuit Board Safety Relays
Reduce connection errors on circuit boards that control machine guards and other safety devices. Also known as force-guided contact relays, they have contact pairs that won’t close at the same time, even if contacts stick or weld shut. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes. Use them to control high-power components, such as fans and heaters, from a low-power circuit.

Hazardous Location Relays
Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.
Relays with screw terminals or spring-clamp terminals are considered interface relays, so they’re placed between your controller and components to isolate the input and output circuits. This means they protect your component from voltage spikes while amplifying the relay’s signal and reducing interference for reliable transmission. They are often used for switching applications, such as small motors and pilot lights. The included relay socket mounts 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. With no screws to shake loose with vibration, the terminals hold tight over time.

Timer Relays
Turn machinery, such as paint and conveyor lines, on and off after a set period of time. These timer relays plug into relay sockets (sold separately) for fast installation and replacement.
Relay sockets mount on 35 mm DIN rail (also known as DIN 3) or flat surfaces.
