Installation and Wiring
Input wiring
The digital input signal of the Web-IO 4.0 is connected to the
terminal labeled “In”.
Voltages above approx. 80Veff referenced to the “N” terminal
are recognized as an “ON” signal and indicated by the green
“IN” LED. A switching state must be present for at least 50ms
to be reliably detected.
In the example above the outer conductor for the supply is
connected to the digital input of the Web-IO using a poten-
tial-free contact.

WARNING
The input signal must always originate from the same outer
conductor as the supply voltage.
