Dry Contact Output Card
The NMC-64 consists of maximum 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 contact
outputs.
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 need the addition of external protections under normal conditions.
