SIRIUS safety relay basic unit standard series relay enabling circuits

SIRIUS safety relay basic unit standard series relay enabling circuits 3 NO contacts plus relay signaling circuit 1 NC contact US = 110 - 240 V AC/DC 50/60 Hz screw connection SIRIUS 3SK1 safety relay for autonomous safety applications.
The standard 3SK111 basic units are characterized by simple and variable functionality and thus offer an economic entry into the world of safety switching devices. They are ideal for safety functions with only a few sensors and few enabling circuits. These devices have comprehensive, worldwide approvals and are therefore ideally suited for global use and export.
The devices are available as a 24 V version or with wide-voltage range, relay or semiconductor outputs, as well as through a screw or spring-type connection (push-in).
Extensive accessories such as sealing covers, push-in flaps for wall mounting and coding pins simplify the handling.
The 3SK safety switching devices replace the proven 3TK28 series.
Safety is a SIRIUS business.
