Use of the potential bridges for I/O modules without shield contact element
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 can be inserted between the facing terminals 9 and 29, 10 and 30, 19 and 39,
and 20 and 40.
