The DC expansion units are provided with digital inputs/outputs as well as
analog inputs/outputs (￫ Section “Connecting DC inputs of the EASY4..-
DC-ME expansion units“,Page 39).
Two devices are available:
• With the EASY406-DC-ME you can read one “voltage”, “current” or
“temperature” analog value via the first analog input (terminals 2 - 6) and
via the second analog input (terminals 7 - 11).
• The EASY411-DC-ME allows you to evaluate measured values at the
same time via the six analog inputs (terminals 2 - 11), and read voltage,
current or temperature analog values via two inputs each.

Voltages are measured in the 0 - 10 V signal range. A potentiometer with an
upstream resistor that is connected between the supply voltage and
reference potential can be used as a setpoint potentiometer. For voltage
measuring, connect the output of the sensor to the voltage input (terminal 2
or 7), ￫ section Figure 39:, “Setpoint potentiometer with upstream
resistor”, page 41.

You process the analog input and output values using
permanently assigned marker words (MW) which you configure
and program in easySoft-Pro.
