Siemens Sirius 3SK1 Safety Relay

SIRIUS safety relay Basic Unit Advanced series with time delay 0.5-30 s Relay activation circuit 2 NO instantaneous 2 NO delayed Us = 24 V DC screw terminal safety relays SIRIUS 3SK1 for autonomous safety applications. 3SK112 Advanced basic units offer universal application thanks to their multifunctionality and flexible expansion options. They form an innovative system landscape that makes it possible to implement even complex safety functions with a large number of sensors and outputs. With device connectors, the number of inputs and safe outputs can be expanded reliably and easily without increased wiring outlay between the devices. Drives up to 3 kW can be integrated directly into the 3SK system with fail-safe SIRIUS 3SK11 motor starters using device connectors. All components have worldwide approvals and are therefore ideal for global use and export. The units are available with relay or semiconductor outputs, instantaneous or delayed, each with different time intervals and all with either screw or spring terminals (push-in). Extensive accessories such as sealing covers, clip-in shoes for wall mounting, and coding pins make handling easier. Input and output expansions as well as an independent power supply can be used with device connectors without additional wiring expenses. 3SK safety relays replace the proven 3TK28 series. Safety is a SIRIUS business.
