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