DLA73 Pump Alternating Relay
DLA73 is relay made to alternate 2 pumps in a multiple pump system. In case of need (i.e.: overflow) the second 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 suitable both for back and front panel mounting
