Sirius 3TK28 Emniyet Rölesi, 4 Güvenlik Kontağı, Ayarlanabilir, Tek veya Çift Kanallı, 24 → 240 V ac/dc

3TK28 26, Configurable Safety Relay, 8 Selectable Functions

Simultaneously monitors all of the sensor and actuator functions and ensures that outputs are shut down in a safety-relevant fashion. The safety relay has two terminals for the sensors: The cascading input CAS/OS as sensor input S1. The following components can be connected at the sensor input: sensors with contacts, e.g. EMERGENCY STOP or position switches, electronic sensors, e.g. light grids and light barriers, contact mats, magnetically operated switches, NC/NC or NC/NO. The cascading input can be ANDed with other safety relays or to control the device from a machine control system. Suitable for the following applications: up to category 4 according to EN 954-1, up to SIL 3 according to IEC 61508
