1)
It is advisable to mark the selected switch setting in these fields.
On one 465 analog input module, you can insert four cards for the
connection of four inputs each, and secure them with a screw.
There are voltage divider, shunt and through-connection cards for the
various ranges.

For a defined mode (50 mV or 500 mV), you can insert cards with
different ranges for every four inputs, e.g. for the 500 mV mode:
• • 4 inputs, range ± 500 mV; 1 card 6ES5 498-1AA11
• • 8 inputs, range ± 20 mA; 2 cards 6ES5 498-1AA41
Unused inputs must be short-circuited (with Pt 100 operation, this also
applies to the unused current outputs).
Note that the bus interface of the module is activated with 24 V via
enable lines F+ and F- at the front connector.
