The NMC-PRO Climate consists of a maximum of 8 output cards, all of which (or some) can
be dry contact output cards; each card consists of 8 outputs, in total maximum 64 dry

The dry contact output card can be used to drive devices of various voltages depending on
what is connected to it. When more than 40 outputs of type 24VAC are required the dry
contact output card can be configured as seen in drawing below.
The dry contact output card consists of surge and lightening protection circuits and doesn’t
