What is the function of the auxiliary contact?
The auxiliary contact (NC) indicates the relay status: it is closed when the relay is active and open in case of fault.
Can this relay be used with light curtains?
Yes, it is designed for monitoring light curtains and emergency stops, with redundancy and dynamic testing.
What is the maximum conductor cross-section?
The connectable cross-section is 0.2 mm² to 2.5 mm² with or without ferrules.
How to reset the relay after a fault?
Turn off and then restore the power supply. If the fault persists, check the wiring and the safety inputs.
Does the relay support an inductive load?
Yes, for inductive loads such as contactors, provide a freewheeling diode across the coil.
What safety level is achieved?
This relay is certified SIL 3 according to IEC 62061 and category 4 according to EN 954-1.
Where can I find the detailed wiring diagram?
The diagram is provided in the user manual downloadable on the product page.
How to test the relay without equipment?
Simulate a fault by opening the safety input: the relay should deactivate and the auxiliary contact open. Return the input to the safe state to reactivate.
