4.16 Digital Output Module SM 422;

DO 16 24 VDC/2 A;

(6ES7422-1BH10-0AA0)

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

• 2 A output current

• 24 VDC rated load voltage

The status LEDs also indicate the system status even when the front connector is

not inserted.

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.
