DLA71 Pump Alternating Relay
DLA71 is relay made to alternate 2 or 3 pumps in a multiple pump system. In case of need (i.e.: overflow) the second, or even the third pump can be activated together with the first one.
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.
