12.5.2 Connections used for digital input and output terminals

Different connection options are described below using 24 V DC terminals as an example.

For the 120 V AC/230 V AC area, the data changes accordingly. A connection example is

provided in the relevant terminal-specific data sheet.

In the following diagrams, U

S

is the supply voltage because this potential jumper is

accessed in the majority of terminals. The relevant terminal-specific data sheet

specifies whether the I/O is supplied from the main circuit U

M

or the segment circuit
