5.10 Front connector for the I/O modules
Use of the potential bridges on 35 mm digital modules
With the delivered potential bridges, for digital modules with a maximum rated voltage of
24 V DC, you can bridge the terminals for the voltage supply and thus reduce the wiring
effort. The bridges are used to connect the following pairs of opposing terminals: 9 and 29,
10 and 30, 19 and 39 as well as 20 and 40.
Reference
Additional information on wiring the inputs and outputs can be found in the manuals for the
I/O modules.
