Connecting DC inputs of the EASY4..-DC-ME expansion units
In addition to the analog inputs/outputs, the EASY4..-DC-ME DC expansion
units are provided with the digital input R1. In addition to R1 you can also
always use the analog 0 V - 10 V voltage inputs R2/R3 (terminals 2 and 7) as
additional digital inputs and actuate them with up to 24 V DC.
Both expansion devices output a 0 signal on R2/R3 if the voltage goes below
8 V DC and outputs a 1 if this voltage is exceeded.

R2/R3 can always be used as additional digital inputs, even if
they have not been expressly configured in the programming
software as analog voltage inputs. Current and temperature
inputs cannot be used as digital inputs.
