DETAILED DESCRIPTION

DLA71

The DLA71 is an electronic relay to alternate 2 or 3 pumps in a multiple pump system, without PLC.
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.
If the system is continuously working with only one pump, after working for 6 hours, DLA71 stops the pump and automatically starts the next pump. This rotation is repeated every 6 hours of single and continuative work of a pump.
The LED indicates the power supply and the output relay.
