8.7.33 Digital outputs (4.3.9)
Fig. 81 Digital outputs
Description
Each digital output can be activated and related to a certain
function.
As standard, the system has two digital outputs.
If the system incorporates an IO 351B module (option), the
number of digital outputs is 9.
All digital outputs are shown so that their physical position in the
system can be identified.
Example
DO1 (IO 351-41) [71]:
For further information on the connection of various digital
outputs, see the wiring diagram supplied with CU 352.
