Pump Blocking Unit UBN-2

UBN-2 is a continuously operating alarm system equipped by the spark-proof circuit as the explosion safety measure. UBN-2 has 10 channels, explosion safety mark ExiaIIC.

The sensor operation by any of six parameters makes UBN-2 provide a signal to open dry contact for automated switching-off. UBN-2 has an option to disable any of six channels. The disable concerns the commands to block the pump and start the alarm. The sensor operation by any of four other parameters makes UBN-2 provide a signal by each channel separately to open dry contact for pump stopping. UBN-2 operates with the external light and sound alarm units.
