Key Functions & Applications
Multi-Function Safety Monitoring
The relay is typically used to monitor safety devices such as:
-
Emergency stop (E-Stop) buttons
-
Safety doors or gates
-
Light curtains
Configurable Reset Modes
Supports two reset options:
-
Autostart – The system resets automatically once the safety condition is restored.
-
Monitored Start – Requires a manual reset button to restart the system.
Cross-Circuit Monitoring
Detects short circuits between input channels to prevent unsafe conditions such as fail-to-on faults.
Cascading Capability
Multiple safety relays can be linked together to create more complex safety logic without requiring a dedicated safety PLC.
