Digital Inputs and Outputs (Terminal Block X0)
Terminal numbers No. 7 to No. 10 on Terminal Block X0 can be used as either
inputs or outputs. Configuration takes place in the Device Configurator. Depending
on the configuration, the technical data corresponds to that of a normal digital
input or output:
Configured as an input:
Input type:
Source operation, electrically connected

Inputs and outputs
NOTE: Subject terminal block X0
The terminal Uext serves to feed the outputs to terminals 7 ... 10th
If at least I/O 4 ... 7 operated as a receipt, the following must be considered:
If this external supply U ext which outputs the power off and the inputs I/O 4 ... 7
is still tension on the supply voltage of the outputs O 0, ... 3 and I/O 4 ... 7 via the
built-in output transistor of the I/Os diode fed back and would feed the device con-
nected to the output load.
