Control relay
The control relay REL (changeover contact) can be used as VDE 0833-4 compliant output.
The IRIS-Net software allows the user to configure the parameters or fault types for which the
changeover contact should switch over. To integrate the device into the hazard alert systems,
a normally-closed contact (standby current principle) is recommended.
!
Caution!
The maximum load of the control relay is 32V/1A.
