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

Compact Spade-Terminal Relays
Fit these relays where standard spade-terminal relays are too big. You can connect them three ways. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals. An LED indicator shows you the status of the relay, so you know it’s connected and wired correctly.
Relays that control 2 or more circuits have a lockable test button, so you can test their function. When you press the button, the relay switches contacts. Use this button when checking a relay for proper function before installing it, or when investigating issues with wired relays.
Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. You can also mount them to a flat surface using screws.

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 circular-pin terminals or quick-disconnect terminals are hermetically sealed—completely air- and watertight—to shield internal parts from gases, moisture, and other contaminants. They plug into relay sockets (sold separately) for easy installation.
Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces.

Solid State DIN-Rail Mount Multifunction Timer Relays
For fast installation, mount these relays to 35 mm DIN rail (also known as DIN 3 rail). They also mount to flat surfaces. With no moving parts, these solid state relays last longer and require less maintenance, are quieter, and switch faster than mechanical relays. They provide a variety of timing functions in one relay.
Use relays with DIP switches for more precise control than knobs. They make it easier to set multiple relays to the same timing range.
Relays that control 4 circuits require a relay socket (sold separately) to attach to DIN rail.
