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).

Circuit Board Relays
Smaller than relays with electrical wiring, these relays fit in compact devices. Mount them through holes on circuit boards with their solder pin terminals. Use them to control heaters, fans, and other high-power components from a low-power circuit.
Solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter than mechanical relays.

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.
