Inserting Range On one 465 analog input module, you can insert four cards for the connection
Cards of four inputs each, and secure them with a screw. There are voltage divider,
shunt and through-connection cards for the various ranges.

Mode 50 mV
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:
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.
