Siemens Sirius 3TK28 24V DC

The Siemens SIRIUS 3TK28 safety relays with relay enabling circuits  feature positively-driven NO and NC contacts, in pairs, which means if  one of the contacts welds, then the other contact is used to shut down  the circuit. A positively-driven feedback signal contact (NC contact)  detects the fault of the defective NO contact.

The manufacturer declares that the safety components of the SIRIUS 3TK series in the designs marketed by us comply with the applicable basic safety and health requirements of the EC Directives* stated (including amendments) and that the stated standards* were applied in their design and construction. Here they are used to evaluate sensors and ensure safety-related shutdown in case of a hazard. They also check and monitor the sensors, actuators, and the safety-related functions of the safety relay.

Features:

  • Minimum programming time and high degree of user friendliness thanks to parametrisation display.
  • Device versatility means reduced storage requirements.
  • Compact design.
  • Electrically isolated safety outputs.
