1BH11-0AA0)
Features
The digital output module SM 422; DO 16 x DC 24 V/2 A has the following features:
● 16 outputs, isolated in two groups of 8
● Output current 2 A
● Nominal load voltage 24 VDC
The status LEDs also indicate the system status even when the front connector is not

A note about commissioning
The following technical feature applies to the digital output module SM 422;DO 16 x
DC 24 V/2 A with the order number 6ES7422-1BH11-0AA0 but not to the digital output
module SM 422; DO 16 x DC 24 V/2 A with the order number 6ES7422-1BH10-0AA0:
To commission the module, it is not necessary to apply load voltage (1L+ and 3L+, for
example,) to each group of 8 outputs. The module is fully operative even if only one group is
supplied with L+.
Note
It is no longer possible to switch off all the outputs by disconnecting a single L+ supply as
might have been the case with the previous module (6ES7422-1BH10-0AA0).
