Two-wire proximity switches have a residual current in the 0 state. If this
residual current is too high, the device only detects the 1 state at the input.
With two-wire proximity switches or sensors with similar residual current
consumption use therefore the inputs I7 and I8.
Use an additional input circuit if several inputs are required with a higher
input current.
Increased input current
The following input circuit can be used in order to prevent interference and
also when using two-wire proximity switches:
Figure 24:Increasing the input current on the easy800 standard AC version
Figure 25:Increasing the input current at the AC expansion unit EASY618-AC-RE
A resistor can be connected in series with the circuit shown in order to
restrict the inrush current.

When using a 100 nF capacitor, the drop out delay of the input
increases by 80 (66.6) ms at 50 (60) Hz.
