Terminals
These relays handle the high starting (inrush) currents that often occur when turning on a vehicle. Also known as ISO relays, their blade terminals meet ISO 8092-1 dimensional standards to fit in road vehicles for easy maintenance and repair.
Relays for surface mounting have a tab for added security in high-vibration applications.
Relays with surge suppression coverage prevent damage to sensitive equipment by reducing the 300V to 500V spike that happens when you switch relays off. Relays with partial surge suppression coverage bring this spike down to 100V. Relays with full surge suppression coverage eliminate the voltage spike.
Relays with dual output let you control two separate loads or circuits independently. For example, in a car window, these relays could control it moving up and down.

Solid State High-Starting-Current Vehicle Relays
Crimp-On
Terminals
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.

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.

Safety Relays with Diagnostic Capabilities
Control and diagnose issues with safety-critical circuits. These relays have a microprocessor that monitors safety components, such as emergency stops and light curtains, and sends a signal to stop the operation if a failure is detected and restart when the issue is resolved. They also help with diagnostic tasks because of their feedback circuit, which allows basic relays to communicate their status back to the safety relay. These relays have a duplicate set of input and output signals, so they’ll still stop the controlled device if one of the inputs fails.
IP20 rated, they have recessed terminals which prevent fingers and other objects from touching live circuits. These relays have been tested to multiple safety standards and can help achieve PL, SIL, or CAT system ratings. They also meet ISO and IEC standards for machine safety.
Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation.
Relays and auxiliary contact blocks with delayed safety outputs are often used where power must be maintained after an input signal is received. For example, after a stop button for a machine is pressed, the guard door will stay locked until the machine cycle is finished.
Auxiliary contact blocks (sold separately) allow you to control more components, such as signaling devices or basic relays.
