Terminal and block diagram of the analog on-board I/O
This section contains the block diagram of the analog on-board I/O (X10) and various wiring
options.
For information on wiring the front connector, establishing the cable shield, etc., refer to the
S7-1500, ET 200MP (http://support.automation.siemens.com/WW/view/en/59191792
)
system manual.
Note
You can use and combine the different wiring o
ptions for all channels. Note, however, that
unneeded terminals of an analog input channel must not be connected.

Infeed element
The infeed element is inserted on the front connector and serves to shield the analog on-
board I/O.
Note
The analog on
-board I/O does not require power to be supplied by the infeed element. The
infeed element is, however, necessar
y for shielding.
