Characteristics:
● X222: DI 3.0 to 3.7 are connected as rapid inputs.
● The inputs have no signaling (status LEDs).
● The inputs are not isolated.
● It is not possible to connect a 2-wire BERO.
Power supply for digital inputs (X111, X222, X333: Pin 2):
● The internal power supply (P24OUT) is taken from the general power supply of module
● Alternatively, an external power supply can be connected if the load at the digital outputs
