Solid State Screw Terminal Relays
With no moving parts, these solid-state relays are fast switching and require less maintenance, last longer, and are quieter than mechanical switches.
Relays with high-starting-current protection are designed with integrated circuits that prevent damage from the large burst of electricity when a device, such as a motor or pump, turns on.
Heat sinks disperse heat to increase the relay’s current rating. Mount them to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces. Before mounting one-circuit relays, silicone compound or a thermal pad should be placed between the heat sink and relay. Silicone compound is sold separately for heat sinks that do not include it but require it. Two-circuit relays don’t require silicone for mounting.

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.
Auxiliary contact blocks (sold separately) allow you to control more components, such as signaling devices or basic relays.
