Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. An LED indicator lights up when these relays are connected, so you can quickly confirm that they’re wired correctly. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.

Relays with an integrated heat sink disperse heat to increase the relay’s current rating.

Relays with an integrated fan are best for applications that generate more heat. The fan automatically turns on to provide additional cooling. When the temperature exceeds 176° F, an alarm sends a signal to an external device, such as a controller or indicating light.

With no moving parts, these solid state relays require less maintenance and last longer, switch faster, and are quieter than mechanical relays. They can handle high starting (inrush) currents. The blade terminals meet ISO 8092-1 dimensions, ensuring they are compatible with the electrical connections in road vehicles you need to maintain or repair. Also known as ISO relays or automotive 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 SIL2 are tested for applications with a probability of failure of 0.1% to 1%. They’re often used for emergency shutdowns, and fire, gas, and overpressure detection.

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.
