Siemens Sirius 3SK1 Safety Relay

SIRIUS safety relay Basic unit Advanced series with time delay 0.05-3 s Relay-activating circuits 2 NO immediate 2 NO delayed Us = 24 V DC Spring-type terminal (push-in) safety relays SIRIUS 3SK1 for autonomous safety applications. 3SK112 Advanced base units offer universal use thanks to their multifunctionality and flexible expansion options. They form an innovative system landscape that allows even complex safety functions to be implemented with a large number of sensors and outputs. With the help of device connectors, the number of inputs and safe outputs can be reliably and easily expanded without increased wiring expenditures 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. Devices are available with relay or semiconductor outputs, immediate or delayed, each with different time intervals and all with either screw or spring terminals (push-in). Extensive accessories such as sealing covers, plug 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 costs. The 3SK safety relays replace the proven 3TK28 series. Safety is a SIRIUS business.
