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.

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 a fuse holder slot give you the option for additional overload protection. If the current exceeds the fuse’s rating, the fuse will blow and break the circuit. This prevents the relay from overheating, breaking, or causing a fire. The fuse holder is sold separately. You can use these relays without the fuse holder as a standard interface relay.

Safety Relays
Receive signals from safety monitoring relays or controllers to switch devices off and on because of a system failure. Also known as force-guided or mechanically linked contacts, the interlocking opposing contacts on these relays cannot be open or closed at the same time. To keep your system from receiving false switching signals, the interlocking opposing contact must remain open even if a contact welds closed.
IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits. These relays have been tested to safety standards that can help you achieve your system's PL (performance level) and SIL (safety integrity level). Choose a relay with a PL and SIL rating to meet the needs of your system. Higher ratings indicate greater safety protection. As your system becomes more complex, you generally require a higher safety protection level. Mount them to 35mm DIN rail (also known as DIN 3 Rail).
Relays that meet SIL3 are tested for applications with a probability of failure of 0.01% to 0.1% and are used for preventing fires, explosions, or toxic releases. Relays that meet CAT 4 withstand circuit surges in electrical applications up to 600V.
When a failure is detected, relays with self-monitoring circuitry signal the controller to remove power and prevent restarting until the issue is resolved.
Relays with nondetachable contacts have auxiliary contacts that won’t separate from the relay if there is shock or vibration. Relays with mirror auxiliary contacts have contacts that are normally closed and cannot be open at the same time as a normally open main contact.

High-Starting-Current DIN-Rail Mount Timer Relays
Reduce voltage fluctuations and stress on shafts and bearings when starting up three-phase motors. These timer relays start with motor contacts in a star configuration, then switch to a delta configuration after a set delay. Since star configuration takes less voltage to start than delta, these relays prevent voltage dips that often happen when a motor starts and are gentler on mechanical parts. Mount these relays directly to 35 mm DIN rail (also known as DIN 3 rail) for quick installation.
