3SK1111-1AB30
1 NC contact, Us = 24 V AC/DC, screw terminal connection.
SIRIUS 3SK1 safety relay for stand-alone safety applications.

The 3SK111 Standard basic units are characterized by simple and flexible functionality and therefore offer an economical entry into the world of safety relays. They are ideally suited for safety functions with only a few sensors and a small number of enabling circuits.

These devices have comprehensive worldwide approvals, making them ideally suited for global use and export. The devices are available as 24 V versions or with a wide voltage range, with relay or semiconductor outputs, and consistently with screw terminals or spring-loaded terminals Push-In.

Extensive accessories, such as sealable covers, plug-in lugs for wall mounting, and coding pins, make handling easier.

The 3SK safety relays replace the proven 3TK28 series.
Safety is a SIRIUS business.
