Characteristics
The digital output module SM 422; DO 16
24 VDC/2 A has the following
features.
•
16 outputs, isolated in two groups of 8
•

Caution
To commission the module, the rated load voltage must be applied at least once to
each group of 8 outputs (e.g. connection of 1L and 3L). If voltage is not applied to
a group due, for example, to 1L and 2L failing, all the outputs switch off, even
those in the second group. The status LED continues to function in the same way.
