Siemens Dual-Channel Safety Relay Safety Relay

Starter Kit SIRIUS 3SK2 for demanding safety applications involving more than one safety function.

• Basic 3SK2 unit - 22.5 mm (3SK2112-2AA10)
• SIRIUS Safety Software ES V 1.0 standard
• Standard USB PC-cable

• Parameterizable inputs and outputs
• Snap mount for easy installation
• Spring loaded terminals
• Short Circuit Protection

The 3SK2 basic units offer many inputs and outputs within a narrow unit to meet demanding safety applications with several independent safety functions. Flexible application options are enabled by powerful semiconductor outputs, as well as by expandability with additional 3SK1 output expansions and seamless integration into the main conducting path using 3RM1 Failsafe motor starters. Extensive logic functions are available for assigning parameters to independent disconnections of the fail-safe outputs.

The SIRIUS Safety ES engineering software allows easy commissioning and offers extensive diagnostic options. Easy implementation of muting and protective door monitoring, for example, is possible by means of prefabricated logic blocks.

Safety is a SIRIUS business.
