Digital inputs

The digital inputs acquire binary control signals from the process level. Typically, these are mechanical contacts such as normally closed contacts or normally open contacts, electronic sensors such as inductive proximity switches, optical sensors or other methods in order to generate a low/high signal in the sense of control technology. Thanks to integrated multi-function I/Os, the CX70xx has a total of 8 digital inputs, 24 V DC, filter 3 ms, type 3.

Digital inputs 1:
Configurable digital inputs.

The digital inputs have a 3 ms input filter. The signal status of each individual input is displayed by an LED. For digital inputs 3, 4, 5 and 6, additional filter settings can be made in the appropriate CoE objects and, for example, the resolution and filter time can be set.
