SIRIUS 3TK28 Safety Relays Basic Units SIRIUS 3TK28 Safety Relay, Basic Units

The SIRIUS 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.
