Description
SIRIUS safety relay basic unit Advanced series with time delay 0.05-3 s relay enabling circuits 2 S instantaneous 2 S delayed US = 24 V DC screw connection SIRIUS 3SK1 safety relay for autonomous safety applications.
The basic devices Advanced 3SK112 offer universal applications thanks to multi-functionality, as well as flexible expansion options. They form an innovative system landscape that can implement complex safety functions with a variety of sensors and outputs. With device connectors, the number of inputs and safe outputs can be extended reliably and easily without wiring between the devices. Drives up to 3 kW can be integrated directly into the 3SK system with the SIRIUS 3SK11 fail-safe motor starters using the device connector. 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, as well as continuously with screw or spring-type terminals (push-in).
Extensive accessories such as sealing covers, push-in flaps for wall mounting and coding pins simplify the handling. Input and output extensions, as well as a separate power supply can be used by means of device connector without additional wiring expenditure.
The 3SK safety switching devices replace the proven 3TK28 series.
Safety is a SIRIUS business.
