2) Type of operation and allocation to inputs D1 and D2 can be selected.
Identical devices must not be connected to both inputs.
3) Same sequence for both valves but valves driven alternately
Observe the max. simultaneous load on outputs Y1 ... Y4: Max. 9.5 VA each (see data sheet N3874).
A current list of compatible devices is available in the DESIGO RX hardware overview
(N3804).
