Siemens 3SK1111-1AB30 3SK11111AB30 safety switching device 24 V/DC, 24 V/AC rated current 5 A
 
SIRIUS safety switching device basic device standard series relay enabling circuits 3 NO contacts plus relay signaling circuit 1 NC contact Us = 24 V AC/DC screw connection SIRIUS 3SK1 safety switching device for self-sufficient safety applications.
The standard 3SK111 basic devices are characterized by simple and variable functionality and therefore offer an economical entry into the world of safety switching devices. They are ideal for security functions with only a few sensors and a few enabling circuits. These devices have comprehensive, worldwide approvals and are therefore ideal for global use and export.
The devices are available as a 24 V version or with a wide voltage range, relay or semiconductor outputs, and all with screw or spring-loaded connections (push-in).
A wide range of accessories such as sealing covers, insertion tabs for wall mounting and coding pins make handling easier.
The 3SK safety switching devices replace the proven 3TK28 series.
Safety is a SIRIUS business.
