The 3RR22 current monitoring relays have been expanded by an IO-Link interface for the transfer of digital measured values to the control. The monitoring relays' autonomous function remains available, independently of the control.
Application area
� Monitoring for current exceedance and shortfall
� Monitoring for line breakage
� Monitoring for no-load operation and load shedding, in case of V-belt breakage or pump idling
� Monitoring for overload, e.g. caused by a polluted filter system in pump applications
� Monitoring for the functionality of electric loads such as heating
� Monitoring for incorrect phase sequence with mobile systems such as compressors or cranes
� Monitoring for incomplete ground faults, e.g. due to damaged insulation or humidity
