2. Installation
2.4 Connection terminals
2.4.4 Connect digital inputs
The inputs of the easyE4 devices switch electronically.
Once you have connected a contact via an input terminal, you can reuse it as a con-
tact in your circuit diagram as often as you like.
Connect the contacts, for example buttons or switches, to the input terminals of the
easyE4 device.
