Product Description Ordering Key
DLA 73 T B23 2P
DLA73 is relay made to alternate 2 pumps in a multi- ple pump system. In case of need (i.e.: overflow) the sec- ond pump can be activated together with the first one. The unit actives the third output relay (i.e.: for alarm signal) by closing one indipendent input contact.
In case more than one pump is required to start at the
same time, the pumps start
10 s after the previous to avoid big inrush current.
The LED indicates the state of the alarm and the output relay.
35.5 mm wide housing suit- able both for back and front panel mounting.
