12.2 PP 72/48D PN and PP 72/48D 2/2A PN
• 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 X1,
pin 2 (P24). Alternatively, an external power supply can be connected if the load at the digital
outputs becomes too high.

Terminal assignment for the digital outputs
The following figure shows an example of the terminal assignment for the digital outputs on
connector X111. Connectors X222 and X333 are assigned analogously.
Characteristics
• No galvanic isolation.
• Protection against: Short-circuit, overtemperature, and loss of ground.
• Automatic disconnection in case of undervoltage.
