The module provides several diagnosis functions Ä Chapter 1.6.2.1.5.6 “Diagnosis”
on page 400.
The following figure is an example of the internal construction of the analog input AI0. The
analog inputs AI1...AI3 are designed in the same way.

CAUTION!
Risk of damaging the analog input!
The 250 W input resistor can be damaged by overcurrent.
Make sure that the current through the resistor never exceeds 30 mA.
The following figures are an example of the connection of analog sensors (voltage) to the input
I0 of the analog input/output module AX561. Proceed with the inputs I1 to I3 in the same way.
