– X222: Inputs 3.0 to 3.7 are connected as rapid inputs; this means the input filter 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.
The following figure shows an example of the terminal assignment for the digital inputs on
connector X111. Connectors X222 and X333 are assigned analogously.
