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.

Relays that control 3 and 4 circuits are built to IEC dimensional standards and are often called IEC contactors.

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.

Safety Relays

Receive signals from safety monitoring relays or controllers to switch devices off and on because of a system failure. When a failure is detected, the self-monitoring circuitry signals the controller to remove power and prevent restarting until the issue is resolved. An inspection window allows you to easily see the status of your system.

These relays have nondetachable auxiliary contacts, so they won’t separate from the relay if there is shock or vibration. Also known as force-guided or mechanically linked contacts, their interlocking opposing auxiliary contacts cannot be open or closed at the same time. They have mirror auxiliary contacts, which are normally closed and cannot be open at the same time as a normally open main contact. To keep your system from receiving false switching signals, the interlocking opposing auxiliary contact must remain open even if a contact welds closed.

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, and CAT system ratings. They also meet ISO and IEC standards for machine safety.

Mount them to 35mm DIN rail (also known as DIN 3 Rail). They can also be mounted to flat surfaces.

Machine-Guard Relays

The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding. The screw terminals are recessed to prevent accidental contact with live connections. Mount them on 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces. These relays are built to IEC dimensional standards.

Auxiliary contact (sold separately) allows you to add a signaling device or control another relay.
