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).

DIN-Rail Mount Solid State Interface Relays


With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission. The relay’s LED indicator shines when it’s powered on, so you know at a glance which relays are wired correctly and what the switching position is. These relays are often used for switching small motors and sensors. Rated IP20, they prevent fingers and other objects from touching live circuits.
Mount them on 35 mm DIN rail (also known as DIN 3 rail) with the included socket. Relays disconnect from the socket for easy replacement.
Relays with spring-clamp terminals connect and disconnect to wires without needing to turn screws. With no screws to shake loose with vibration, these terminals hold tight over time.

DIN-Rail Mount Touch-Safe Screw Terminal Relays
Quickly and safely mount these relays on 35 mm DIN rail (also known as DIN 3). IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits.
Auxiliary contacts (sold separately) allow you to add a signaling device or control another relay. You can add one auxiliary contact to all of these relays. For relays with 12 terminals, you can add two side-mount auxiliary contacts.
Use replacement coils to swap out a broken coil or change the input voltage of a relay. They are only compatible with relays that have 12 terminals. The full load current of the relay must match the full load current range of the coil.

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.

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.

Interface Safety Relays

These relays pair the transmission reliability of an interface relay with the fail-safe operation of a safety relay. Use them to communicate signals to devices like motors or sensors. They have interlocking contacts—also known as force-guided or mechanically linked contacts—so opposing contacts won't close at the same time. This minimizes the chance of arcing, so electricity won't jump across the contacts and interfere with your relay or system. They also have an interface that isolates input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal. Mount them on 35 mm DIN rail (also known as DIN 3 rail). The relays disconnect from the socket for quick replacement.
