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.
