SIRIUS safety relay basic unit standard series electronic enabling circuits 2 enabling circuits plus 1 signaling circuit Us = 24 V DC 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 economical entry into the world of safety relays. They are ideally suited for safety functions with only a few sensors and a 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 variant or with a wide voltage range, relay or semiconductor outputs, as well as with screw or spring-loaded connection (push-in). Extensive accessories such as sealing covers, push-in tabs for wall mounting and coding pins make handling easier. The 3SK safety relays replace the proven 3TK28 series. Safety is a SIRIUS business.
