1.10 Engineering
The easyE4 series makes it possible to combine multiple voltage variants. Each base
device can be wired with up to 11 EASY-E4-...-...E1(P) expansions with different
power supplies.
1.10.1 Length of Signal input cables
1.10.1.1 Digital inputs
Severe interference can cause a signal 1 on the inputs without a proper signal being
applied.
Therefore, observe the following maximum cable lengths without additional circuitry:
