Digital inputs
Characteristics
• X222: Inputs 3.0 to 3.7 are connected as rapid inputs; this means the input lter has a max.
delay time of 600 μs.
• The inputs have no signaling (status LEDs).
• The inputs are not isolated.
• It is not possible to connect 2-wire BEROs.
Terminal assignment for the digital inputs
The following gure shows an example of the terminal assignment for the digital inputs on
connector X111. Connectors X222 and X333 are assigned analogously.
