Siemens SINUMERIK 828D PPU Series - Specification of the Digital Inputs

7.7.3.4 Specification of the digital inputs
Terminal assignment for the digital inputs
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.
The following figure shows an example of the terminal assignment for the digital inputs on
connector X111. Connectors X222 and X333 are assigned analogously.

Figure 7-49 Terminal assignment for the digital inputs
Power supply for digital inputs (X111, X222, X333: Pin 2):
The internal power supply (P24OUT) is taken from the general power supply of module X1,
pin 2 (P24). Alternatively, an external power supply can be connected if the load at the digital
outputs becomes too high.
