Product details
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.
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
Can be used in ambient temperatures up to 70 °C
Standard relay enable circuits (positively driven)
Suitable for use with Expansion module 3TK28 30
Standards
EN 60204-1, EN 92, EN 954-1.
