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.

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.

Solid State Surface-Mount Timer Relays
Attach these relays to a flat surface using the mounting hole. They have no moving parts, so compared to mechanical switches, they require less maintenance, last longer, and are quieter.
Delayed start (delay-on-make) relays allow you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping a lubricant immediately, but it does not start rotating until the set time has elapsed.
Switches with a potentiometer (variable switch) allow you to adjust the delay within the range.
